Product Description
M5 A2 Stainless-Steel Socket Cap Set Screws
These M5 socket cap set screws are manufactured from A2 stainless steel and feature a standard M5 × 0.8 metric coarse thread. They are fully threaded and available in selected lengths from 8mm to 35mm.
The cylindrical socket cap head incorporates a 4mm 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, automotive components, instrumentation, electronics, brackets, enclosures, tooling, jigs, fixtures and general engineering assemblies requiring a fully threaded M5 stainless-steel fastener.
Installation Guidance
Confirm that the mating component has a standard M5 × 0.8 metric thread. These screws are not interchangeable with M5 fine-pitch fasteners. Screw length is measured from beneath the socket cap head to the end of the fastener.
Use a correctly fitting 4mm hex key and apply a tightening torque suitable for the joint, mating material and application. Avoid using carbon-steel torque figures unless the strength class of the stainless-steel screw has been confirmed.
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.
