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 3/4 inch, with a 1/4 inch outside diameter, and a 7/16 inch 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 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.
