Product Description

The PROTO J54318H is an 18-piece Torx bit socket set built for 1/2 inch drive ratchets and impact tools. The set covers both fractional inch and metric hex sizes, giving technicians a single organized kit for a wide range of fastener applications. Sizes span 1/4 inch through 3/4 inch in fractional increments and 6 mm through 19 mm in metric, making it well suited for maintenance, assembly, and disassembly work across HVAC equipment, electrical panels, plumbing fixtures, and general mechanical systems. The complete set weighs 11.5 pounds and is packaged in a single kit with an item quantity of one.

This set is intended for professional tradespeople who regularly encounter both inch and metric Torx fasteners on commercial and residential equipment. The 18 included sockets address the most commonly encountered 1/2 inch drive hex sizes in HVAC service, electrical maintenance, plumbing, and pool equipment repair. The dual measurement coverage eliminates the need to carry separate inch and metric sets on the job, reducing tool bag weight and setup time during service calls.

Installation Notes

Select the correct socket size before applying torque to avoid rounding fastener heads. Always verify drive size compatibility between the socket and the ratchet or impact tool before use. Inspect sockets for wear or cracking before each use, particularly when used with impact tools. Follow applicable equipment manufacturer service procedures and relevant safety codes when performing fastener work on pressurized, electrical, or gas-containing systems.
