1 5/8" #8 Modified Truss Screw 50 lbs.

Modified Truss Head with Self-tapping point.

 The threads on these screws also cut their own threads into either wood, plastic or sheet metal. Modified truss head screws feature an over-sized domed head with a flange, similar to an integral washer. Modified truss head screws have a 100 degree undercut which creates a larger area beneath the screw's head for a larger bearing surface.
