Dottie MT38 Drill Bit, 3/8" 1-3/4" Magnetic Nut Driver

Get faster, more reliable installs with the Dottie MT38 magnetic nut driver — engineered for technicians who install security, surveillance and network equipment. This 3/8" nut driver combines a hardened S2 steel core and heat-treated construction to resist wear in high-torque applications, while an industrial-strength magnet holds fasteners securely to prevent drops and speed one-handed work.

At 1-3/4" length, the MT38 gives added reach to access recessed nuts inside camera mounts, patch panels and monitoring enclosures, reducing the need to reposition ladders or disassemble brackets. The design supports quick bit changes and consistent torque transfer, making it ideal for low-voltage, IT and physical security professionals who demand reliability on the job. Packaged in quantities of 10, it’s a cost-effective choice for service fleets and installation crews.

Whether you’re mounting cameras, wiring access control or terminating network racks, the Dottie MT38 magnetic nut driver delivers durable performance and time savings. Add it to your toolkit for smoother, cleaner security and networking installations.
