L H Dottie Co T8321TB 8/32x1 Tamper Resistant Truss Screw 100pk

Product Description

The L H DOTTIE CO T8321TB is an 8/32 x 1 inch tamper-resistant machine screw with a truss head and pin-in Torx star drive. The pin-in drive recess requires a matching security bit for installation or removal, which limits unauthorized access to fastened assemblies. This screw is suited for electrical enclosures, junction boxes, access panels, and commercial or industrial fixtures where standard Phillips or slotted fasteners would allow unwanted removal. Electricians and security-conscious installers use these screws when code, specification, or site policy requires tamper resistance at fastened access points. Sold in a 100-count pack.

These screws are commonly used in electrical and low-voltage installations where panel covers, cable management hardware, or enclosure lids must be secured against tampering. Typical applications include commercial electrical panels, data and telecom enclosures, transit or public facility fixtures, and any installation requiring restricted-tool fastening. The truss head provides a wide, low-profile bearing surface suited to thin-gauge sheet metal and plastic panels.

Installation Notes

Installation requires a pin-in Torx security bit matched to the drive size. Power down all circuits and follow NFPA 70 (NEC) lockout/tagout procedures before fastening or removing screws on or near energized enclosures. Use a torque-limiting driver to avoid stripping the drive recess or damaging thin panel material. Store unused fasteners in a labeled container to prevent mixing with non-tamper-resistant hardware.
