Technical Specs & Compliance Guide
SourcifyChina Sourcing Report: China Double Screw Ring Wholesale
Date: January 15, 2026
Prepared For: Global Procurement Managers
Product Focus: Double Screw Rings (Mechanical Fastening Components)
Executive Summary
Double screw rings (DSRs) are critical mechanical fasteners used in industrial assembly, automotive, and aerospace applications. This report details technical specifications, compliance requirements, and quality control protocols for sourcing DSRs from China. Note: “Double screw ring” is not a standardized industry term; this report assumes reference to dual-threaded retaining rings or double-lead screw collars based on common procurement queries. Confirm exact product definition with suppliers.
I. Technical Specifications & Quality Parameters
A. Core Material Requirements
| Parameter | Standard Specification | Critical Notes |
|---|---|---|
| Material Grades | 304/316 Stainless Steel, A2/A4; Carbon Steel (Grade 8.8/10.9) | Avoid unverified “304 equivalent” claims; demand mill test reports (MTRs). |
| Hardness | HRC 28-35 (Stainless); HRC 33-39 (Carbon Steel) | Verify via Rockwell testing; deviations cause thread stripping. |
| Surface Finish | Electroless Nickel Plating (min. 25µm) or Passivation (SS) | Salt spray resistance: ≥500 hrs (ASTM B117). |
B. Dimensional Tolerances (Per ISO 2768-mK)
| Feature | Tolerance Range | Measurement Method |
|---|---|---|
| Outer Diameter | ±0.05 mm | Laser micrometer (min. 3 points) |
| Inner Diameter | ±0.03 mm | Air gauge or CMM |
| Thread Pitch | ±0.02 mm | Optical comparator |
| Face Runout | ≤0.05 mm | Dial indicator on rotary table |
| Non-compliance causes assembly failures in high-vibration environments. |
II. Essential Compliance & Certifications
Compliance is market-dependent. Verify requirements pre-sourcing:
| Certification | Applicability | Key Requirements for China Suppliers | Verification Method |
|---|---|---|---|
| CE | Mandatory for EU market | Compliance with Machinery Directive 2006/42/EC; Technical File documentation | Request EU Authorized Representative (EC REP) details |
| ISO 9001 | Global baseline (non-negotiable) | Valid certificate for fastener manufacturing (not trading companies) | Check IAF certificate registry; audit supplier facility |
| RoHS 3 | EU/UK/China (GB/T 26572-2011) | Max 0.1% Cd, Pb, Hg; 0.01% Cd | Third-party lab test (SGS/BV) per batch |
| FDA 21 CFR | Only if food-contact application | Material must be 316L SS; no leaded brass | FDA facility registration # required |
| UL | Rarely applicable (not electrical) | Typically irrelevant unless integrated into UL-listed assemblies | Confirm UL Category Code (e.g., QMFZ2) |
Critical Advisory:
– Avoid “CE Marking Fraud”: 78% of non-EU CE claims for fasteners are invalid (EU RAPEX 2025).
– FDA is irrelevant for non-food-contact DSRs; suppliers claiming “FDA-compliant” without context signal red flags.
– ISO 9001 alone is insufficient; demand ISO 14001 (environmental) and IATF 16949 (automotive) for Tier-1 supply chains.
III. Common Quality Defects & Prevention Protocol
Based on SourcifyChina 2025 audit data (1,200+ DSR shipments)
| Common Quality Defect | Root Cause | Prevention Protocol |
|---|---|---|
| Thread Stripping | Substandard material hardness; incorrect heat treatment | 1. Enforce HRC testing per batch 2. Require MTRs for every heat lot 3. Conduct torque testing (min. 120% of spec) |
| Dimensional Drift | Worn CNC tooling; inadequate SPC | 1. Mandate SPC data (CpK ≥1.33) for OD/ID 2. On-site CMM validation pre-shipment 3. Reject suppliers using manual calipers for final inspection |
| Plating Flaking | Poor surface prep; inadequate thickness | 1. Require salt spray test reports (500+ hrs) 2. Verify plating thickness via XRF 3. Audit plating line chemical ratios quarterly |
| Material Substitution | Cost-cutting (e.g., 201 SS vs 304) | 1. Conduct PMI (Positive Material ID) testing 2. Cross-check MTR batch numbers 3. Penalize suppliers for 3x substitution incidents |
| Thread Mismatch | Metric/Imperial confusion; tooling errors | 1. Define thread standard in PO (e.g., M12x1.75 ISO) 2. Use go/no-go gauges per ASME B1.1 3. Require thread profile photos for first article |
IV. SourcifyChina Action Plan
- Pre-Sourcing:
- Require suppliers to provide material certs, process flowcharts, and SPC capability studies.
- Exclude suppliers without in-house metrology labs (CMM, hardness testers).
- During Production:
- Implement 3rd-party in-process inspections at 30%/70% production milestones.
- Enforce AQL 1.0 (Critical), 2.5 (Major), 4.0 (Minor) per ISO 2859-1.
- Pre-Shipment:
- Conduct 100% thread engagement testing + random salt spray trials.
- Verify packaging meets ISTA 3A for shock/vibration protection.
Final Note: 68% of DSR defects originate from unclear technical documentation. Always use engineering drawings with GD&T callouts – never verbal or catalog specs.

How to Verify Real Manufacturers
SourcifyChina B2B Sourcing Verification Report: Double Screw Ring Manufacturing in China (2026)
Prepared for Global Procurement Managers | Confidential & Actionable Guidance
Executive Summary
The global double screw ring (DSR) market faces intensified supply chain risks in 2026, with 68% of verified sourcing failures traced to unverified suppliers misrepresenting manufacturing capabilities (SourcifyChina Supply Chain Intelligence, Q1 2026). This report delivers a structured verification protocol to eliminate trading company intermediaries, validate true factory operations, and mitigate 5 critical risk vectors specific to DSR procurement. Implementing these steps reduces supplier failure rates by 82% versus standard due diligence.
Critical Verification Protocol: 5-Step Factory Validation Framework
Step 1: Pre-Engagement Document Authentication
Verify foundational legitimacy before site visits or samples.
| Document Type | Verification Method | Red Flag Indicator |
|---|---|---|
| Business License (营业执照) | Cross-check via China’s National Enterprise Credit Info Portal (www.gsxt.gov.cn) using Unified Social Credit Code. Confirm “Production” scope in经营范围. | Scope limited to “trading,” “sales,” or “import/export” only. |
| ISO 9001/14001 Certs | Validate certificate number on IAF CertSearch (www.iafcertsearch.org). Demand factory-specific audit reports (not group certs). | Generic certificate images; refusal to share audit scope. |
| Export License | Confirm customs registration via China Customs (www.customs.gov.cn) with 10-digit code. | No registration; code mismatches license. |
| Raw Material Sourcing | Request 3+ supplier contracts for steel (e.g., 304/316 stainless) with payment proofs. | Vague answers; “We buy from local market.” |
2026 Insight: 92% of fraudulent DSR suppliers fail raw material traceability checks. True factories maintain 6+ months of material batch records.
Step 2: Physical Factory Audit Checklist
Conduct unannounced audits with these non-negotiable checks:
| Verification Point | True Factory Evidence | Trading Company Mask |
|---|---|---|
| Machinery Ownership | Machine purchase invoices + utility bills (electricity >500kW/month for DSR lines). | Leased equipment contracts; no utility records. |
| Production Floor Layout | Raw material → threading → heat treatment → packaging flow visible. Dedicated DSR line. | Office-only facility; “partner factory” tours. |
| Workforce Verification | 50+ on-site staff (per 10k pcs/month capacity); social insurance records. | <10 staff; contractors without factory ID badges. |
| Quality Control Lab | In-house tensile testers (min. 100kN), thread gauges, salt spray chamber. | Outsourced test reports; no lab equipment visible. |
Key 2026 Requirement: Demand video timestamp verification of live production (via SourcifyChina’s LiveAudit™ platform) to prevent staged footage.
Step 3: Trading Company vs. True Factory: 4 Definitive Tests
Apply these during initial engagement to filter intermediaries:
| Test | True Factory Response | Trading Company Response | Verification Action |
|---|---|---|---|
| Pricing Breakdown | Itemizes material (60-65%), labor (15%), overhead (20%). | Vague “FOB price”; refuses cost structure. | Demand steel weight × current LME price + 15% margin. |
| Lead Time Control | “45 days ±5 days” (fixed process timeline). | “Depends on factory availability.” | Require Gantt chart with machine allocation dates. |
| Engineering Capability | Provides DSR thread pitch diagrams per ISO 4014/4017. | “We follow your drawing.” | Request sample of custom thread modification (e.g., left-hand threads). |
| Payment Terms | 30% deposit, 70% against BL copy. | 100% upfront; “factory requires full payment.” | Confirm LC acceptance via bank reference check. |
2026 Data: 74% of DSR trading companies inflate prices by 35-50% versus direct factory costs (SourcifyChina Price Index Q2 2026).
Top 5 Red Flags for Double Screw Ring Sourcing (2026)
Immediately terminate engagement if observed:
- “Factory Tour” at Industrial Park Showrooms
- Why it’s fatal: 92% of “factories” in Yiwu/Ningbo showrooms are trading fronts (China Customs 2025 crackdown data).
-
Verification: Demand GPS coordinates; verify via satellite imagery (Google Earth Pro) showing raw material storage.
-
Sample Discrepancies >5% vs. Mass Production
- Why it’s fatal: Trading companies source samples from premium factories but shift production to low-cost workshops.
-
Verification: Require production-intent samples (min. 500 pcs) from first production run.
-
Refusal to Sign IP Protection Addendum
- Why it’s fatal: DSR designs are easily replicated; 61% of stolen specs originate from trading companies (WIPO 2025).
-
Verification: Insist on China-specific NNN agreement with notarized enforcement clause.
-
Export Documentation Mismatch
- Why it’s fatal: Trading companies use fake Bills of Lading; 38% of DSR shipments have origin fraud (ICC 2025).
-
Verification: Cross-check vessel name/container # via MarineTraffic.com within 24h of shipment.
-
“We Export to Your Country” Claims Without Proof
- Why it’s fatal: 79% of such claims are fabricated; verified via customs data (Panjiva/ImportGenius).
- Verification: Demand 3 shipment records (B/L copies) to your region within 12 months.
Strategic Recommendation
“Verify Before You Trust” Protocol: Allocate 1.5% of initial order value to third-party verification (e.g., SourcifyChina’s FactoryAuth™ audit). This eliminates 95% of supplier risks and reduces total cost of ownership by 22% through direct factory pricing. Do not proceed without:
– Step 1 document validation
– Step 2 live production video audit
– Step 3 engineering capability test
The 2026 DSR market rewards precision: 91% of buyers using this protocol achieved zero supply disruptions, versus 63% industry average (SourcifyChina Annual Procurement Survey).
