Poorly applied or unverified coatings (e.g., zinc plating, Dacromet) may not deliver the specified corrosion protection or torque performance. This is especially problematic in humid or saline environments.
6. Supply Chain Transparency Issues
OEMs often face challenges tracing the origin of screws, particularly when sourced through intermediaries. Opaque supply chains increase risks of counterfeit parts, ethical sourcing violations, and quality deviations.
7. Overlooking Minimum Order Quantities (MOQs) and Customization Limits
Some manufacturers resist small-batch or custom orders for non-standard sizes like M3.5, pushing buyers toward off-spec alternatives that compromise design integrity.
Best Practices to Avoid Pitfalls
– Partner with certified, audited suppliers experienced with precision fasteners.
– Request material test reports (MTRs) and dimensional inspection reports.
– Verify IP rights for specialty drive types before production.
– Conduct pre-production sampling and in-house testing.
– Use procurement contracts that specify compliance, liability, and audit rights.
By addressing these pitfalls proactively, businesses can ensure reliable performance, legal compliance, and long-term cost efficiency when sourcing M3.5 screws.
