Security Screws Feature High Torque Tamper-Resistance

BROOKLYN, NY - Tanner Bolt & Nut Inc. has been named the exclusive master distributor in the U.S. for Parker Fasteners Lock-Out® maximum security screw.

Lock-Out screws are a new type of security fasteners featuring a unique patented drive that is engineered to perform in high torque applications. Manufactured under ISO compliance, the screws feature a licensed system that prevents unauthorized access to bolted or screwed compartments by using a custom key/drive configuration. Features include:

High Torque - tests show Parker’s Lock-Out elliptical design disseminates torque across the entire face of the drive at many impact angles allowing greater torque.

Oval Center Pin - inability to drill an oval hole thwarts theft.
