Proto J10030M Impact Socket 1 in Drive 30mm 6-point

Product Description

The PROTO J10030M is a 1-inch drive impact socket designed for heavy-duty fastening and removal tasks in professional shop and field environments. Built around a 30mm hex drive, 6-point socket geometry, this socket delivers concentrated torque to fastener flats, reducing rounding under high-load impact use. The overall length of 2-7/16 inches keeps reach compact while maintaining clearance for standard impact gun anvils. At 1.58 pounds, this is a solid, full-mass socket intended for use with 1-inch square drive pneumatic or hydraulic impact wrenches. Mechanics, ironworkers, heavy equipment technicians, and industrial maintenance crews are the primary users.

This socket is suited for high-torque applications where a 1-inch drive impact wrench is the required tool — heavy truck service, construction equipment, structural fastening, and industrial machinery maintenance are common scenarios. The 30mm size covers a range of large metric fasteners found on drivetrain components, axle hardware, and structural bolted connections. The 6-point contact geometry is the preferred choice for impact work because it minimizes slippage and fastener damage compared to 12-point designs.

Key Features

• 1-inch square drive fits standard heavy-duty pneumatic and hydraulic impact wrenches
• 30mm hex drive, 6-point design concentrates force on fastener flats for reduced rounding
• 2-7/16 inch overall length provides compact reach for tight-clearance applications
• 1.58-pound solid construction supports repeated high-torque impact cycles
• Single-piece socket format — no moving parts, no inserts to fail under impact load

Compatibility

Designed as an OEM-style professional-grade replacement or addition for 1-inch drive impact socket sets used in heavy truck, construction equipment, and industrial maintenance service.

Installation Notes

This socket is installed by mechanics and industrial maintenance technicians using 1-inch drive impact wrenches. Always verify the drive anvil retainer pin and ring are fully seated before applying torque. Inspect the socket for cracks or deformation before each use — do not use impact sockets that show visible damage. Never use impact sockets with standard hand-drive ratchets, as impact-rated sockets are not designed for that application in reverse.
