Proto J5411MH 1/2 Drive 6-point Hand Socket 11 Mm

Product Description

The PROTO J5411MH is a 6-point, 1/2 inch drive hand socket designed for fastener removal and installation in professional mechanical and maintenance environments. Built to ASME B107.5 standards, this standard-length socket measures 11 mm and features a chrome-plated finish that resists corrosion and makes the socket easier to clean after use. The 6-point contact geometry reduces fastener rounding by distributing torque evenly across the flats rather than the corners. At 0.12 pounds, it is a compact, lightweight tool suited for daily use in shop, field, or fleet service settings.

This socket is used by mechanics, millwrights, and maintenance technicians across automotive, industrial, and general equipment service applications. The 1/2 inch drive interface is one of the most common in professional tool inventories, making this socket compatible with a wide range of standard ratchets, breaker bars, and torque wrenches. Standard length makes it appropriate for accessible fasteners where clearance is not a limiting factor.

Key Features

• 11 mm socket size with 6-point contact geometry for reduced fastener rounding

Installation Notes

Install and remove this socket using a 1/2 inch drive ratchet, breaker bar, or torque wrench rated for the fastener application. Ensure the socket is fully seated on the fastener before applying torque to prevent slipping or rounding. Inspect the socket for cracks or deformation before each use and replace if damaged. This tool is intended for hand-drive use only and should not be used with impact drivers.
