Proto J72216 19 Pc 3/8 Drive Metric Deep Impact Socket Set

Product Description

The PROTO J72216 is a 19-piece metric deep impact socket set built for professional-grade fastener work in demanding trade environments. Designed around a 3/8 inch drive, the set covers 6 mm through 24 mm in 6-point configuration, giving technicians a secure, slip-resistant grip on hex fasteners under high torque. The deep profile accommodates extended bolt threads and recessed fastener applications common in mechanical, HVAC, and plumbing service work. All 19 sockets store on an included clip rail for organized tool management and quick socket identification on the job.

This set is suited for residential and commercial mechanical service applications where metric fasteners are standard. The 3/8 inch drive size is a common choice for mid-torque work, balancing reach and control in tight engine bays, equipment cabinets, and service panels. The deep impact design makes it practical for automotive, industrial equipment, and building systems maintenance where standard-depth sockets fall short. Licensed tradespeople and experienced mechanics working in metric-fastener environments will find the full 6 mm to 24 mm range covers the majority of common metric fastener sizes encountered in daily service work.

Installation Notes

This socket set is used by licensed mechanics, HVAC technicians, plumbers, and electricians performing fastener work on metric-fastened systems and equipment. Always select the correct socket size before applying torque to avoid fastener damage. When using with an impact wrench, confirm that the sockets are rated for impact use before applying power. Store on the included clip rail after use to maintain set integrity and prevent loss of individual sockets.
