Our 4-40 x 1/2 Phillips pan head screws are crafted from high-quality 18-8 stainless steel, ensuring durability and resistance to corrosion.

Each screw is equipped with a split lock washer and a regular flat washer, providing enhanced stability and surface protection.

The split lock washer effectively prevents the screw from loosening over time, while the flat washer helps distribute the load evenly to prevent damage to the materials being fastened.

These versatile screws are widely used in electronics, appliances, furniture assembly, and more.
