3/8"-16 x 2" Tamper-Resistant Cap Screws, Torx® Equivalent 6-Lobe with Solid Post, Button Head, Driver Size: 45TXH, Alloy Steel Zinc Plated

Torx® Tamper-Resistant Cap Screws manufactured from heat-treated alloy steel with zinc plating, incorporate a solid post formed in the center of the recess during the heading process. These fasteners are extremely difficult to remove without a special tamper-resistant tool. The Torx® Tamper-Resistant Drive System is recognized as one of the most efficient fastening systems because of its ability to transfer greater torque, reduce load and virtually eliminate tool slippage.
