Our 4-40 x 1/2 Phillips pan head split lock screws are the perfect choice for a wide range of applications.

These screws are fully threaded and feature a zinc plating that offers excellent corrosion resistance.

The split lock washer included with each screw prevents loosening, ensuring a secure fit in metal, plastic, or wood materials.

The narrow flat washer helps distribute the load evenly, protecting the material from damage during fastening.
