Product Description
M4 A2 Stainless-Steel Socket Cap Set Screws
These M4 socket cap set screws are manufactured from A2 stainless steel and feature a standard M4 × 0.7 metric coarse thread. They are fully threaded and available in lengths from 5mm to 25mm.
The cylindrical socket cap head incorporates an internal hexagon drive, providing secure tool engagement while allowing installation where access around the fastener head is restricted. A2 stainless steel provides good general-purpose corrosion resistance for indoor and moderately exposed applications.

Typical Applications
Suitable for machinery, instrumentation, electronics, model engineering, small mechanical assemblies, brackets, enclosures, tooling and general engineering applications requiring a compact stainless-steel fastener.
Installation Guidance
Confirm that the mating component has a standard M4 × 0.7 metric thread. Screw length is measured from beneath the socket cap head to the end of the fastener.
Use a correctly fitting 3mm hex key and apply a tightening torque suitable for the joint, mating material and application. Avoid excessive tightening, particularly when installing into aluminium, plastic or other softer materials.
Stainless-steel threads can be susceptible to galling during installation. Using a suitable anti-seize compound and installing at a controlled speed can help reduce this risk.
A2 stainless steel is suitable for many general-purpose applications but may not be appropriate for prolonged exposure to salt water, marine environments or aggressive chemicals. A4 stainless steel should be considered where greater corrosion resistance is required.
