Description

21mm 12-Point Socket

Drive Size: ³/₈"
Drive Type: Square Drive

The 21mm 12-point socket is a heavy-duty powerhouse, representing one of the largest sizes available in a 3/8" drive configuration. This specific size is a critical requirement for automotive work involving lug nuts, spark plug wells in certain performance engines, and larger suspension bolts. By pairing a 21mm capacity with a 3/8" drive, this socket provides the unique ability to deliver high-torque performance in areas where a bulkier 1/2" drive tool simply would not fit, offering mechanics a versatile solution for specialized high-load fasteners.

The 12-point (double-hex) geometry is engineered to maximize efficiency in challenging environments. With twice the engagement points of a traditional 6-point socket, it allows for faster tool placement and requires only a 30-degree swing arc to continue turning. This is especially valuable when working on chassis components or deep within an engine bay where range of motion is severely limited by surrounding parts, ensuring you can maintain a steady rhythm without constant repositioning.

Forged from industrial-grade Chrome Vanadium (Cr-V) steel, this socket is built to withstand the extreme pressures of heavy-duty mechanical work. The high-strength alloy is precision heat-treated to ensure the socket walls remain intact and rigid under high stress. To protect against the corrosive environment of a professional garage, the tool is finished with a mirror-polished chrome coating that resists rust, prevents the pitting caused by road salt, and allows for a quick cleanup after messy jobs.

Internally, the socket is precision-machined to provide a high-tolerance, exacting fit on 21mm hardware. This design prioritizes contact with the flat surfaces of the fastener, effectively distributing torque and preventing the rounding of corners that can lead to stripped bolts. Whether you are performing a brake overhaul or working on industrial machinery, this 21mm socket provides the professional-grade reliability and precision fit required for the most demanding tasks.
