The PROTO J7226H is a 6-point impact socket designed for use with 3/8 inch drive impact wrenches and ratchets. The socket measures 13/16 inches (26 mm) in size and has an overall length of 1-7/32 inches. Built for the demands of professional trade work, this socket handles the high-torque output of pneumatic and electric impact tools. The 6-point hex drive geometry grips fastener flats squarely, reducing rounding under load. Licensed tradespeople in mechanical, HVAC, plumbing, and general industrial maintenance rely on impact-rated sockets like this one where standard chrome sockets are not appropriate.
The J7226H fits standard 3/8 inch drive impact tools and is suited for both bench work and in-field service. The 13/16 inch size covers a common fastener dimension found across HVAC equipment panels, pipe flanges, mechanical assemblies, and structural fasteners. Its compact 1-7/32 inch overall length makes it practical in tighter access situations where a longer socket would not clear surrounding components.
Designed as an OEM-style replacement and standard fitment impact socket for 3/8 inch drive impact wrenches, air ratchets, and hand ratchets used across HVAC, plumbing, electrical, and general mechanical service applications.
Install and remove using a 3/8 inch drive impact wrench, air ratchet, or hand ratchet. Always use impact-rated sockets with impact tools — do not substitute standard chrome sockets, which can fracture under impact loads. Inspect the socket for cracks or deformation before each use and remove from service if damage is found. Power down or de-energize any equipment before breaking fasteners on electrical enclosures or mechanical assemblies.
