OPSIT® REVERSE THREAD SCREWS

Opsit® is a reverse thread sheet metal screw that installs counter-clockwise, thereby tightening when standard removal is attempted. This innovative approach means that these reverse thread bolts and screws, including the counter-clockwise bolt screws, tighten when standard removal methods are attempted, enhancing security. Opsits® have a Tri-Wing ® drive and are only available in the Truss Head (Low profile for added security). Stainless steel counter-clockwise screws only. For screws with a unique design, featuring two drilled spanner holes, take a look at the Snake Eyes® spanner screws.
