Proto J69206 Impact Socket Set 13pc 1/4 in Drive Metric

Product Description

The PROTO J69206 is a 13-piece metric impact standard socket set built for 1/4 inch drive tools. The set covers sizes from 4 mm to 10 mm and features 6-point geometry throughout, which seats firmly on fastener flats and reduces rounding under impact torque. Sockets are rated for impact use, meaning they are manufactured to withstand the shock loads generated by pneumatic and cordless impact drivers. This set is a practical choice for HVAC technicians, electricians, plumbers, and mechanical contractors who work with metric fasteners on equipment panels, motor mounts, and control assemblies.

This socket set is suited for light-duty metric fastener work in residential and commercial service environments. The compact 1/4 inch drive size makes it well matched for tight spaces commonly encountered during equipment access, control board removal, and panel work. The included sizes cover the most common metric fastener range found on HVAC equipment, electrical enclosures, and plumbing fixture hardware. Sockets ship on a clip rail for organized storage in a tool bag or tray.

Installation Notes

This set is intended for use by trade professionals working with metric fasteners on mechanical, electrical, and plumbing equipment. Always de-energize electrical panels and shut off equipment power before removing fasteners on live assemblies. When using impact drivers, confirm the socket is fully seated on the fastener before applying torque to avoid rounding. Store sockets on the included clip rail when not in use to prevent loss of individual pieces.
