Tamper resistant socket head cap screws use a pin-in socket drive — a standard hex socket with a center pin — requiring a specialized bit for removal. Available in 18/8 stainless steel across a range of thread sizes. Used in precision assemblies, electronics, and industrial equipment where high-torque fastening and tamper deterrence are both required.
