SATA GL34420T 1/2'' Drive 6 Point Thin Wall Impact Deep Socket 27mm

Thin-wall means the socket walls are thinner than standard sockets. This reduces the socket's outer diameter, allowing access in cramped areas where regular sockets won't fit, while still providing enough strength for typical high-torque use.

Specifications include a 1/2'' drive, 27mm hex size, 6-point configuration, deep socket design, thin-wall construction, and suitability for impact use. The off-corner loading design helps protect fasteners from rounding under high torque.

Compared to standard sockets, the thin-wall design provides greater access in tight spaces, and the deep socket reaches recessed fasteners. The 6-point grip and off-corner loading enhance grip reliability and reduce rounding, especially under high-torque impact use.

Ideal for automotive work, engine bays, brake and suspension jobs, or any scenario where a 27mm fastener sits in a confined area and a standard socket won't fit or clear obstacles.

Attach the socket to a compatible 1/2'' drive impact wrench or ratchet. Fit the 27mm hex onto the fastener, apply steady torque, and avoid excessive hammering. When the fastener loosens, remove and recheck seating to prevent rounding or slippage.

Yes. This socket is designed for use with impact tools and 1/2'' drive equipment. Ensure you use a compatible impact tool and follow safe torque practices to maximize durability.

Off-corner loading shifts contact away from the corners of the fastener, reducing rounding and wear under high torque. This helps maintain fastener life and socket durability during demanding impacts.

Measure the flats across your bolt or nut to confirm 27mm. If you’re unsure, check the service manual for the fastener size or use calipers to verify. When in doubt, compare against a known 27mm fastener in your toolkit.

Inspect for cracks or wear before use. Keep the socket clean and dry, avoid using on damaged fasteners, and wear appropriate PPE. Use the correct 1/2'' drive tool and avoid overloading beyond the tool’s torque rating to preserve thin-wall integrity.

Yes, SATA offers a range of thin-wall sockets in different sizes. If you frequently work in tight spaces, a size range or set can provide comprehensive coverage and potential cost savings over buying individual pieces.
