Proto J5015MH Deep Hand Socket 15 Mm 3/8 Drive

Product Description

The PROTO J5015MH is a deep hand socket designed for professional hand-tool use in mechanical, automotive, and industrial service applications. Built to a 15 mm socket size with a 3/8 inch drive, this 6-point socket provides full-face contact on fastener flats, reducing the risk of rounding during high-torque applications. The chrome-plated finish resists corrosion and makes surface cleaning faster between jobs. The deep length profile accommodates protruding bolt threads, studs, and recessed fasteners that standard-depth sockets cannot reach. It is a standard single-piece hand socket intended for use with ratchets, breaker bars, and torque wrenches with a matching 3/8 inch drive.

This socket is suited for residential and commercial mechanical service work including automotive repair, HVAC equipment assembly, plumbing fixture installation, and general equipment maintenance. The 15 mm size is commonly encountered on metric fasteners throughout engine bays, HVAC unit frames, pump housings, and electrical enclosures. The deep configuration is particularly useful when working on studded mounts or any fastener application where a shallow socket would bottom out before seating fully on the nut or bolt head.

Key Features

• 15 mm socket size for metric fastener applications
• 3/8 inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• 6-point geometry for full-face contact and reduced fastener rounding
• Deep length profile clears protruding threads and recessed fasteners
• Chrome-plated finish for corrosion resistance and easy cleaning

Compatibility

Designed as an OEM-style hand socket for use with 3/8 inch drive ratchets, extensions, and torque wrenches in standard metric hand-tool sets.

Installation Notes

Install and remove by a qualified mechanic or service technician using a properly rated 3/8 inch drive ratchet or torque wrench. Ensure the socket is fully seated on the fastener before applying torque to avoid slippage or fastener damage. Inspect the socket for cracks or wear before each use and retire any socket showing visible deformation. No power-down or system shutoff is typically required for hand-socket use, but always follow applicable site safety procedures when working on energized or pressurized equipment.
