FAQ

1. Can truss head washer self-drilling screws be used without pre-drilled holes?

Yes. The integrated drill point is designed to penetrate thin to medium-gauge metal directly, eliminating the need for pre-drilling in most standard metal-to-metal fastening applications. Proper selection of screw diameter and length is recommended to match the substrate thickness.

2. How does the washer headI need to shorten; finish second FAQ sentence, typo "How does the washer" cut. Need fix.
