Proto J72117 Deep Impact Thin Wall Socket Set 9 Pc

Product Description

The PROTO J72117 is a 9-piece deep impact thin wall socket set designed for use with a 3/8 inch drive. Built from alloy steel, these sockets feature a 6-point contact design that reduces rounding on fastener heads under high-torque conditions. The thin wall construction allows access in tight clearances where standard impact sockets cannot fit. The set spans 1/4 inch through 3/4 inch, covering the fastener range most commonly encountered in mechanical, HVAC equipment service, and industrial maintenance work. Licensed trades and professional technicians are the primary users of this set.

This socket set is suited for residential and commercial service applications where impact-rated tooling is required. The deep profile accommodates extended fasteners and studs common in equipment panels, compressor mounting, and structural fastener removal. The thin wall design is particularly useful when working in recessed bolt pockets or confined equipment bays. The 9 individual sizes in this set address the full range of fractional inch fasteners typical in trade service environments.

Installation Notes

Impact sockets must be used only with impact-rated drive tools — do not use standard chrome sockets with impact wrenches. Inspect sockets for cracks or deformation before use and replace any damaged sockets immediately. Ensure the drive tool and socket are fully seated before applying torque to prevent slippage or ejection. This set is intended for use by qualified trade professionals following applicable workplace safety standards.
