21MM 3/4' DRIVE 6PT DEEP IMPACT SOCKET

Features

• 21 mm socket size — suitable for metric fasteners common in automotive, machinery, and heavy maintenance.
• ¾″ (19.05 mm) drive — designed for larger impact drivers, breakers and heavy-duty ratchets.
• 6-point design — maximises contact on bolt flats for improved grip and reduced rounding.
• Deep length — reaches into bolt wells, long studs or recessed assemblies.
• Impact-rated construction — built to withstand high torque loads from impact tools.

Benefits

• Increased reach: Deep length allows access to fasteners hidden behind components or within recesses.
• High torque compatibility: Suitable for use with ¾″ impact tools, offering professional-level performance.
• Better fastener engagement: 6-point profile ensures stronger contact and less chance of stripping.

Extra Information

• Best suited for professional workshops, heavy equipment servicing and industrial maintenance.
• Always use from a compatible ¾″ drive impact tool and matched socket accessories. Using smaller drive sockets may lead to tool damage.
• Inspect sockets periodically for wear, especially after frequent high-torque use. Replace if any cracking or deformation is observed.

Specifications

Safety

• Always wear safety glasses and hearing protection when using impact tools; high-torque tools may eject fragments.
• Ensure the socket is fully seated on the fastener before applying torque; slipping can cause injury or damage.
• Use only impact-rated sockets with impact drivers or breakers; standard sockets may crack or fail under load.
• If you notice any cracking, deformation or unusual wear on the socket, discard it immediately.
