Proto J5419M 19mm 12-point 1/2 Drive Hand Socket

Product Description

The PROTO J5419M is a 19 mm, 12-point hand socket designed for use with a 1/2 inch drive ratchet or breaker bar. Chrome-plated and built to standard length, it fits into everyday fastener work on mechanical and industrial jobsites. The 12-point geometry allows engagement at 30-degree increments, useful in tight spaces where full swing is limited. Licensed mechanics, maintenance technicians, and industrial trades reach for this socket when working on fasteners in the 19 mm range across a wide range of equipment and assemblies.

This socket is suited for general mechanical work including automotive, heavy equipment, and industrial maintenance applications. The standard length profile makes it appropriate for most open-access fastener locations. It pairs with any 1/2 inch drive tool in the technician's kit, including ratchets, torque wrenches, impact-rated extensions, and breaker bars where the chrome finish is appropriate for hand-drive use.

Key Features

• 19 mm socket size for metric fastener applications
• 12-point design allows engagement at 30-degree increments
• 1/2 inch drive compatible with standard ratchets, breaker bars, and torque wrenches
• Chrome-plated finish for corrosion resistance and clean appearance

Installation Notes

This socket is intended for hand-drive use with 1/2 inch drive tools and is not rated for direct impact use unless confirmed separately. Verify the fastener size before application to avoid rounding. Keep the drive square engaged fully before applying torque to reduce the risk of slippage or fastener damage.
