Types of Interchangeable Heads
Ratchet Heads
Ratchet heads are popular for their ease of use. They allow you to apply torque in a circular motion without removing the wrench from the fastener, making them ideal for tight spaces. Many brands, including ProTorqueTools, offer ratchet heads that provide excellent grip and durability.
Open End Heads
Open end heads are designed for use in tight spaces where a traditional socket wrench may not fit. They are especially useful in plumbing and automotive applications where access is limited. Grainger provides a range of open end heads suitable for various tasks.
Fixed Heads
Fixed heads are designed for specific torque settings and are not adjustable. They are ideal for tasks requiring precise torque application, such as engine assembly. Williams Industrial offers a selection of fixed head torque wrenches that are known for their reliability.
Flare Nut Heads
Flare nut heads are specifically designed for working with flare nuts, often found in plumbing and HVAC systems. These heads provide a secure grip on the nut, preventing slippage. You can find flare nut heads from suppliers like McMaster-Carr.
Box End Heads
Box end heads are designed to grip the sides of nuts and bolts, offering better torque application and reducing the risk of rounding. They are commonly used in automotive and mechanical assembly. Tohnichi offers various box end options that are well-regarded for their performance.
