Torx Tamper-Resistant cap screws incorporate a solid post formed in the
center of the recess during the heading process. The fasteners are extremely
difficult to remove without a special tamper-resistant tool.
Torx Tamper-Resistant screws have been extensively to prevent unauthorized
removal in correctional institutions, hospitals, elementary and secondary
schools, colleges, universities, public places, and retail stores. Torx
Tamper-Resistant cap screws are manufactured either from heat-treated alloy
steel with zinc plating or 18.8 stainless steel.
