Proto J7333M Impact Socket 1/2 in Drive 33mm 6-point

Product Description

The PROTO J7333M is a 6-point impact socket designed for heavy-duty fastening and removal tasks in professional trade and industrial settings. Built from alloy steel, it accepts a 1/2 inch drive and fits 33mm hex fasteners. The overall length is 3.5 inches, making it suitable for standard-clearance applications. This socket meets ASME B107.33M specifications, confirming dimensional and performance compliance for use in critical service environments. It is intended for use with impact wrenches and is a standard tool for mechanics, industrial maintenance technicians, and contractors working with metric fasteners.

The J7333M is used wherever 33mm metric hex fasteners are encountered, including heavy equipment maintenance, fleet repair, and industrial assembly or disassembly work. The 6-point design concentrates drive force on the flat faces of the fastener, reducing the risk of rounding under high-torque impact conditions. It is a practical choice for shops and field technicians who regularly work with large metric hardware on trucks, agricultural equipment, and machinery.

Installation Notes

Installation and removal should be performed by a qualified mechanic or maintenance technician familiar with impact tooling. Confirm the drive tool is rated for impact use before attaching this socket. Inspect the socket for cracks or deformation before each use and replace if damaged. Do not use impact sockets on non-impact hand ratchets in applications exceeding the tool manufacturer's rated torque.
