6 Lobe Star drive recess, similar to Torx® Self-countersinking bugle head in medium & soft density wood Type 17 notched point for fast penetration Threaded approximately 2/3 of shank on most sizes Deep coarse threads for better hold Approved for use in all pressure treated lumber Always specify Type 316 Stainless Steel for Salt Water applications New package sizes, same screws Important Installation Instructions: If the screws are to be driven by a screw gun, be sure the bit is securely seated in the star recess of the screw. Start slowly and gradually increase speed until the head is driven flush. A high driving speed increases the chance of stripping the drive recess. If the tool has an adjustable torque collar, use a piece of scrap lumber to determine the proper setting needed to drive the head flush with the surface. This will prevent the screw head from twisting off.
