Proto J72137M Impact Socket Set 10 Pc 3/8 in Drive Metric

Product Description

The PROTO J72137M is a 10-piece metric impact standard socket set built for professional trade use in HVAC, mechanical, and industrial service applications. The set uses a 3/8 inch drive and covers sizes from 10 mm through 19 mm in 1 mm increments. Each socket is 12-point and rated for impact use, making them compatible with both impact wrenches and hand ratchets. Constructed from steel, these sockets are organized on a clip rail for fast access and secure storage in a service van or toolbox. The set weighs 2.72 pounds and measures approximately 13.5 inches long, 4.1 inches wide, and 2 inches tall.

This socket set is suited for residential and commercial service work where metric fasteners are common. HVAC technicians, plumbers, electricians, and general mechanical contractors will find the 10 mm through 19 mm range covers the majority of metric bolt and nut sizes encountered on equipment panels, motor mounts, pipe hangers, and conduit fittings. The clip rail storage keeps sockets organized and allows quick identification of the needed size on the job.

Installation Notes

Always match the drive size of the socket to the drive size of the ratchet or impact tool before use. When using impact-rated sockets with a powered impact wrench, confirm the socket is fully seated on the fastener before applying torque. Hand-ratchet use is acceptable with this impact-rated set. Store sockets on the clip rail when not in use to prevent loss and maintain set completeness.
