Proto J72143M 7pc 1/2 in Drive Metric Impact Socket Set

Product Description

The PROTO J72143M is a 7-piece metric impact socket set built for use with 1/2 inch drive impact wrenches and ratchets. Each socket is manufactured from steel and features a 6-point design that grips fastener flats directly, reducing the risk of rounding under high torque loads. The set covers sizes from 13 mm through 19 mm, making it a practical range for automotive, mechanical, and industrial fastener work. Sockets are rated for impact use, meaning they are engineered to absorb the shock and torque generated by pneumatic and electric impact tools without cracking or deforming. The set ships on a clip rail for organized storage and quick access on the job.

This socket set is suited for automotive service, equipment maintenance, and general mechanical work where 1/2 inch drive metric fasteners are common. The 13 mm through 19 mm size range covers a wide band of standard metric bolt and nut sizes found on engines, suspensions, frames, and HVAC equipment mounting hardware. The 6-point socket geometry is preferred when working with worn or tight fasteners. Licensed mechanics, fleet technicians, and industrial maintenance trades will find this set fits into standard 1/2 inch drive setups alongside existing breaker bars, extensions, and torque wrenches.

Compatibility

Designed as an impact-rated replacement or addition for standard 1/2 inch drive metric socket sets used with pneumatic, electric, or manual drive tools.

Installation Notes

Impact sockets should only be used with impact-rated drive tools and extensions. Do not substitute chrome or hand-tool sockets in place of impact sockets when using pneumatic or electric impact wrenches, as non-impact sockets can fracture under repeated shock loads. Inspect each socket for cracks or deformation before use and remove from service if damage is found. Follow applicable workplace safety standards when operating impact tools.
