مقبس سداسي من ساتا (1/2") قياس (21mm) موديل (GL13312)

Key specs: 21mm size, 1/2" drive, 6-point design, corrosion-resistant coating, high-quality steel for durability, compact and lightweight, and dual markings (SAE) with knurled metric markings for easy size identification.

Off-corner loading helps distribute torque more evenly and reduces the likelihood of rounding off fastener corners, which improves grip and prolongs fastener life during tightening or loosening.

The dual markings let you quickly identify SAE (imperial) vs. metric sizes. The knurled line on the metric side provides a tactile grip for identifying metric sizes without looking, aiding faster tool selection on the job.

Ideal for automotive tasks (lug nuts, fasteners around engine components), machinery maintenance, and DIY projects requiring 21mm fasteners with a high-torque capability.

Attach the socket to a compatible 1/2" drive ratchet or extension, ensure the fastener is properly aligned, apply steady torque, and avoid using impact tools beyond the socket’s design limits to prevent damage.

Wipe clean after use, keep the coating dry to prevent corrosion, avoid dropping or banging the socket, and store with other sockets in a dry case to prevent moisture exposure.

Ensure proper engagement with the fastener to avoid slippage, use the correct size to prevent rounding, apply torque within recommended limits, and inspect the socket for wear or cracks before reuse.

The coating helps resist rust and corrosion in harsh or humid environments, maintaining a consistent fit and extending service life in tough conditions.
