Questions
Truss head or pan head with a washer?
A truss head gives a similar bearing area in one piece and sits lower. A pan head with a washer is better when you need a spring or tooth washer.
What materials are truss screws used on?
Thin sheet metal, plastic housings and panels where a standard pan head could pull through or crack the part.
Can you match an existing truss screw?
Yes. Head diameters vary between makers, so send a sample or the head dimensions.
