Proto J5348 Deep Hand Socket 8mm 6-point 3/8 Drive

Product Description

The PROTO J5348 is a deep hand socket designed for professional hand-tool use in mechanical, industrial, and maintenance applications. Built for 3/8-inch drive ratchets and extensions, this socket fits an 8 mm fastener with a 6-point contact pattern that grips hex fasteners securely and reduces the risk of rounding. The deep length profile accommodates extended bolt shanks, studs, and recessed fasteners that standard-depth sockets cannot reach. A chrome-plated finish provides corrosion resistance and makes the socket easy to clean in shop environments. This is a single-piece unit suited for use by mechanics, HVAC technicians, electricians, and plumbers who work with metric hardware.

The J5348 fits standard 3/8-inch drive ratchets, breaker bars, torque wrenches, and extensions. Its deep well makes it particularly useful when fastening or removing metric bolts and nuts mounted on studs or in recessed housings — common in equipment panels, motor mounts, and mechanical assemblies found in residential and commercial service work. The 6-point geometry is preferred over 12-point designs when working with worn or tight fasteners. This socket is packaged as a single unit and is appropriate for both toolbox stocking and individual replacement use.

Installation Notes

Install and remove with a 3/8-inch drive ratchet, torque wrench, or breaker bar. Ensure the socket is fully seated on the fastener before applying torque to avoid slippage. Inspect the socket for cracks or deformation before use, and do not use impact drivers or air tools with a hand-rated socket unless it is specifically rated for impact use.
