Zinc, truss-head, combination-drive machine screws have a low rounded top surface with a flat bearing surface greater in area than a round head fastener of the same nominal size. Weaker than a pan or round fastener, but preferred in applications where minimal clearance exists above the head. Fasten with either a Phillips or slot screwdriver to reduce risk of over-tightening and protect the screw and fastened material. Use for any indoor or outdoor projects. 1/4"-20 coarse thread x 1/2" length. *
