Proto J5019M Deep Hand Socket 19mm 12-pt 3/8 Drive

Product Description

The PROTO J5019M is a deep hand socket designed for professional hand-tool applications requiring extended reach on fasteners. Built to a 19 mm socket size with a 3/8 inch drive, this 12-point socket handles hex and rounded fasteners with a full 2.75 inches of overall length. The alloy steel construction with a chrome-plated finish provides corrosion resistance and durability under regular shop and field use. It meets ASME B107.5 standards, making it suitable for use in demanding trade environments including mechanical, HVAC, plumbing, and electrical service work.

This socket is intended for professional mechanics, service technicians, and tradespeople who need a deep-reach 19 mm socket for engine components, flanged fittings, structural fasteners, and equipment assembly. The deep length profile accommodates recessed or studed fasteners that a standard-depth socket cannot reach. Typical applications include automotive service, industrial equipment maintenance, and commercial mechanical systems.

Key Features

• 19 mm socket size with 12-point configuration for broad fastener engagement
• 3/8 inch drive fits standard ratchets, extensions, and torque wrenches
• Deep length at 2.75 inches overall for recessed fastener access
• Alloy steel construction for high-torque durability
• Chrome-plated finish for corrosion resistance and easy cleaning
• Meets ASME B107.5 standard for hand socket tools

Compatibility

Designed as an OEM-style replacement and standard-fit deep hand socket for 3/8 inch drive ratchets, breaker bars, and torque wrenches used across trade and mechanical service applications.

Installation Notes

Install and remove with a 3/8 inch drive ratchet or torque wrench. Ensure the socket is fully seated on the fastener before applying torque to prevent slippage or rounding. Inspect the socket for cracks or wear before use at high torque. This tool is not tether capable and should not be used in elevated work zones where dropped-tool protocols require tethered equipment.
