L H Dottie Co 1156 Spanner Drill Bit Tamper Proof

Product Description

The L H Dottie CO 1156 is a spanner-type drill bit designed for driving and installing tamper-proof fasteners. The 6-point spanner configuration engages security fastener heads that standard bits cannot turn, making it a purpose-built tool for restricted-access hardware installations. Electricians, plumbers, and general contractors reach for bits like this when installing tamper-resistant covers, panels, or fixtures where unauthorized removal must be prevented. Sold individually as a single unit, the 1156 fits into standard bit holders and driver chucks used on the job site.

This bit is suited for commercial and residential trade work wherever tamper-proof spanner fasteners are specified. Common applications include electrical panel covers, public restroom fixtures, elevator interiors, and any installation where building codes or facility requirements call for tamper-resistant hardware. It is a practical addition to a service kit for field technicians who encounter security fasteners across a range of job types.

Installation Notes

Installation and removal of tamper-proof fasteners should be performed by a qualified trade professional familiar with the fixture or panel being serviced. Always de-energize electrical equipment and follow applicable NEC lockout/tagout procedures before accessing any panel or enclosure. Use the bit with a properly rated driver or drill set to the correct torque range for the fastener material to avoid cam-out or fastener damage.
