Overview

These T-27 Torx security barrel nuts are constructed of stainless steel and come in a satin finish. They feature tamper-resistant 6-lobe security drives with center pins that assist in preventing loosening and removal of mounted partition hardware. These fasteners are manufactured with #10-24 threads and have a total reach of 1/2 in., with a 1/4 in. outside diameter, and a 7/16 in. head diameter. T-27 barrel fasteners like these are commonly used with T-27 shoulder screws in commercial restroom applications. Installation and removal of these types of security fasteners requires the use of a Torx driver tool, or insert bits for power-driven tools. Barrel nuts like these are also known as “sex bolts” and “Chicago bolts” in the fastener industry, and they are designed for use where through bolting is desired with a head on both sides, as commonly used for the installation of restroom stall hardware.
