Socket 21 mm 3/4" 6-point Forsage F-56521

Forsage 21 mm 3/4" 6-point socket (model F-56521) is a workshop accessory intended for use with 3/4-inch drive torque wrenches and ratchets. The six-point internal profile ensures firm engagement with hex fasteners to minimize rounding and slipping when applying high torque. Built for tasks that require a 21 mm socket, it is suitable for automotive repair, heavy equipment maintenance and industrial service operations.

Advantages

The 6-point design concentrates contact on the flats of fasteners for reduced rounding and improved torque transfer. A 3/4" drive interface provides compatibility with common heavy-duty ratchets and torque wrenches. The socket's 21 mm size addresses a frequent metric requirement in vehicle and machinery maintenance, offering a reliable fit for corresponding hex bolts and nuts.

Suitable for

• Automotive wheel and suspension work requiring high torque
• Heavy machinery maintenance and field repairs
• Industrial assembly and disassembly of metric fasteners
• Service tasks where a 21 mm socket is specified

Key specifications

• Socket size: 21 mm
• Drive size: 3/4 inch
• Internal profile: 6-point (hex)
• Compatibility: designed for use with 3/4" drive ratchets and torque wrenches
• Typical applications: automotive, heavy equipment, industrial maintenance

How to use

Select a compatible 3/4" drive ratchet or torque wrench and attach the 21 mm socket securely to the drive square. Position the socket over the hex fastener so the 6-point profile fully engages the flats, then apply torque smoothly. When using a torque wrench, set the required torque value and apply force until the wrench indicates the set value. Inspect the socket and fastener for proper fit before applying high torque to avoid slippage.

Usage recommendations

Use the socket with the correctly rated 3/4" drive tools and appropriate torque settings for the fastener material. Do not use damaged or excessively worn sockets. Keep the socket clean and lightly lubricated at the drive interface to facilitate attachment and removal. Store in a dry place to prevent corrosion.
