Proto J10033ML Impact Socket 1 in Drive 33mm 6-point

Product Description

The PROTO J10033ML is a heavy-duty 1-inch drive impact socket designed for high-torque fastener work in professional shop and field environments. Built from alloy steel, it features a 6-point hex drive configuration and accepts a 33mm fastener size with an overall length of 4 inches. The robust construction is engineered to handle the rotational force and shock loads produced by pneumatic, hydraulic, and electric impact wrenches. This socket is sized for heavy equipment, truck, and industrial applications where standard chrome sockets would fail under impact loads. Licensed mechanics, fleet technicians, and heavy-equipment service professionals are the primary users.

The J10033ML is suited for commercial and industrial fastener removal and installation tasks requiring a 1-inch drive tool. Common applications include drivetrain, axle, suspension, and structural fasteners found on heavy trucks, construction equipment, and industrial machinery. The 33mm socket size is frequently encountered on lug nuts, axle nuts, and large structural bolts across a broad range of heavy-duty platforms. Its 4-inch overall length provides clearance for most standard impact applications without requiring an extension.

Key Features

• 1-inch drive fits standard heavy-duty impact wrenches and drive tools
• 33mm 6-point hex socket minimizes fastener rounding under high torque
• Alloy steel construction withstands repeated impact shock loads
• 4-inch overall length suits most direct-drive applications
• Single-piece packaging — no partial sets to manage on the job

Compatibility

Designed as an OEM-style replacement and standard fitment impact socket for 1-inch drive impact wrenches used in heavy-duty mechanical and industrial service applications.

Installation Notes

Installation and removal should be performed by a qualified mechanic or service technician using a compatible 1-inch drive impact wrench or breaker bar. Always verify the socket is fully seated on the fastener before applying torque to prevent slippage or fastener damage. Do not use impact sockets with standard hand-drive ratchets, as the wall thickness and retention system are not designed for that application. Consult applicable torque specifications from the equipment manufacturer before final assembly.
