Proto J5535M 35mm 12-point 3/4 Drive Hand Socket

Product Description

The PROTO J5535M is a 35 mm, 12-point hand socket built for 3/4 inch drive ratchets and breaker bars. Machined from alloy steel with a chrome-plated finish, it delivers the corrosion resistance and surface hardness required for repeated use in professional shop and field environments. The standard-length design measures 2-9/32 inches overall, fitting most fastener access situations without the added reach of a deep socket. Licensed HVAC, plumbing, and mechanical trades rely on this size range for equipment mounting hardware, flange bolts, and large hex fasteners common on commercial and industrial systems.

The J5535M is suited for heavy-duty hand-drive applications where a 3/4 inch drive tool provides the torque needed to break loose or seat large fasteners. Standard-length geometry keeps the socket compact for confined-space access. The 12-point configuration engages fasteners in more rotational positions than a 6-point socket, useful when swing arc is limited. This socket is not tether-capable and is intended for use in environments where drop prevention is managed by other means.

Key Features

• 35 mm socket size fits large metric hex fasteners common on commercial and industrial equipment
• 12-point design allows engagement at 30-degree intervals for restricted-swing applications
• 3/4 inch drive accepts standard 3/4 drive ratchets, breaker bars, and torque wrenches
• Alloy steel construction with chrome-plated finish for corrosion resistance and durability
• Standard length at 2-9/32 inches overall for general-purpose fastener access
• Meets ASME B107.110-2012 and SAE AS955 standards for hand socket performance and dimensions

Compatibility

Designed as a standard OEM-style hand socket for use with 3/4 inch drive ratchets, breaker bars, extensions, and torque wrenches conforming to ASME and SAE drive-tool standards.

Installation Notes

Installation and removal of large fasteners with this socket should be performed by qualified mechanical or trade technicians. Ensure the drive tool and socket are fully seated before applying torque to prevent rounding of the fastener or damage to the socket. Inspect the socket for cracks or wear before each use and remove from service if damage is found. This socket is not rated for impact driver use.
