SATA GL12316 3/8" Drive 6 Point Socket 21mm

The 6-point (hex) design provides a snug fit on hex fasteners, improving torque transfer and reducing the risk of rounding compared to some other socket profiles. It helps you apply torque more effectively in tight spaces.

Specifications: 21mm socket size, for 3/8" drive ratchets, made from chrome vanadium steel, with a polished chrome finish for corrosion resistance and easy cleaning, and a 6-point design for secure fastener engagement.

Off-corner loading shifts contact away from the corners of the fastener, reducing rounding and wear on both the fastener and the socket. This design enhances durability and extends tool life during high-torque use.

Steps: 1) Attach the socket to a 3/8" drive ratchet. 2) Align the socket with the fastener head. 3) Apply steady torque, ensuring the socket is fully seated. 4) Use extensions or adapters as needed for clearance, and avoid applying side loads that could damage the tool.

Keep the socket clean and dry after use, wipe away debris, and store in a dry toolbox. The polished chrome finish resists corrosion, but avoid prolonged exposure to moisture and store away from abrasive materials to maintain its appearance and performance.

- Use the correct size to avoid slippage that could cause injury. - Do not exceed the rated torque of your ratchet or adapter. - Wear eye protection when working with high-torque or stubborn fasteners. - Keep hands clear of the work area and ensure the fastener is properly aligned before applying torque.

The GL12316 offers professional-grade chrome vanadium construction with corrosion-resistant finish at an accessible price, designed for durability in demanding tasks. If it doesn’t meet your needs, refer to Fepy’s standard return policy for eligible items within the specified window.

The GL12314 (20mm) is slightly smaller, which means it fits different fasteners and may be preferred for tasks requiring a 20mm size. Both share the 3/8" drive and 6-point design, but the size difference affects compatibility with certain fasteners and applications.

The GL12318 (22mm) is slightly larger, suited for fasteners with a 22mm head. It shares the same drive size and 6-point design, but the larger size affects fitment on tight fasteners. Compare here: https://fepy.com/product/sata-gl12318-3-8-drive-6-point-socket-22mm
