Proto J5552 1-5/8 in 3/4 Drive 12-point Hand Socket

Product Description

The PROTO J5552 is a standard-length hand socket designed for heavy-duty fastener work in professional trade environments. Built from alloy steel with a chrome-plated finish, this 3/4-inch drive socket fits 1-5/8-inch fasteners and features a 12-point configuration for increased contact angles and flexibility in tight access situations. At 2-5/8 inches overall length, it fits standard socket sets used by mechanics, millwrights, and maintenance technicians working on large-diameter fasteners in industrial, commercial, and heavy equipment applications. It meets ASME B107.110-2012 and SAE AS954G standards, confirming dimensional and performance compliance for professional use.

The J5552 is suited for use with 3/4-inch drive ratchets, breaker bars, and torque wrenches in applications involving large hex fasteners. Typical installations include heavy equipment maintenance, structural assembly, industrial machinery service, and commercial HVAC or mechanical system work where oversized fasteners are common. The 12-point geometry allows the socket to engage fasteners at 30-degree increments, useful in confined spaces where swing arc is limited.

Key Features

• 1-5/8-inch socket size for large-diameter fastener applications
• 3/4-inch square drive compatible with standard heavy-duty drive tools
• 12-point design engages at 30-degree increments for use in restricted spaces
• Alloy steel construction for strength under high-torque conditions
• Chrome-plated finish resists corrosion and aids cleaning
• Meets ASME B107.110-2012 and SAE AS954G standards

Compatibility

Designed for use with 3/4-inch drive ratchets, breaker bars, extensions, and torque wrenches as an OEM-style standard-length hand socket for professional and industrial service applications.

Installation Notes

Installation and removal of large fasteners with this socket should be performed by qualified mechanics or tradespeople using appropriately rated 3/4-inch drive tools. Always ensure the socket is fully seated on the fastener before applying torque to prevent rounding. Inspect the socket for cracks or deformation before each use. This part is not tether-capable and should not be used in overhead or elevated work environments where drop hazards exist.
