Proto J4739C Torx Bit Socket Set 6 Pc 1/4 Drive

Product Description

The PROTO J4739C is a 6-piece Torx bit socket set designed for 1/4-inch drive ratchets and extensions. It covers T10 through T30 Torx fasteners, making it a practical set for technicians who work on HVAC equipment panels, electrical enclosures, and mechanical assemblies where Torx-head fasteners are common. The set weighs 0.38 pounds, keeping it compact and easy to store in a service bag or tool roll. It is suited for professionals who need a dedicated Torx socket set rather than relying on bit adapters.

This set fits typical service and maintenance applications where Torx fasteners appear on equipment covers, motor housings, control panel enclosures, and sheet metal assemblies. The 1/4-inch drive sizing makes it compatible with standard 1/4-inch drive ratchets, extensions, and flex handles already found in most trade tool kits. It is appropriate for HVAC technicians, electricians, plumbers, and general mechanical service professionals who encounter Torx fasteners regularly in the field or shop.

Installation Notes

Always power down or de-energize equipment before removing fasteners from electrical enclosures or control panels. Ensure the correct Torx size is selected before applying torque to avoid fastener damage. A licensed technician or qualified service professional should perform work on energized or pressurized systems per applicable codes. Store Torx sockets in a dry location to prevent corrosion on the drive components.
