Our Phillips pan head split lock washers with regular flat washers are designed for secure and vibration-resistant assembly.

These 4-40 x 3/8 screws are fully threaded and zinc-plated for enhanced corrosion resistance.

The split lock washer provides additional holding power by digging into the mating surface, ensuring a tight fit.

The flat washer helps distribute the load and prevents the screw head from sinking into the material.

Commonly used in electronics, appliances, and furniture assembly for a wide range of applications.
