Socket, impact, 1/2" drive 11 mm — STANLEY 894388

STANLEY impact socket with a 1/2" drive and 11 mm hex opening, model 894388, is made for use with impact wrenches and pneumatic or electric impact tools. The socket is impact-rated to withstand the high torque and shock loads generated during loosening and tightening of hex fasteners. Its 1/2" drive size ensures compatibility with a wide range of impact tools commonly used in automotive repair, construction, and general maintenance.

Advantages

The impact socket features a hardened steel construction and an internal geometry designed for a secure grip on hex fasteners, reducing cam-out and fastener rounding. Heat treatment and impact-specific finishing increase durability under repeated heavy-duty use. The standard 11 mm size covers many common bolts and nuts, while the 1/2" drive provides reliable engagement with impact tools for efficient torque transfer.

Suitable for

• Automotive repair and wheel and brake maintenance
• Construction and assembly work with high-torque fasteners
• Industrial maintenance and equipment servicing
• Pneumatic and electric impact wrench applications

Key specifications

• Drive size: 1/2" (square drive compatible with standard 1/2" impact tools)
• Hex opening: 11 mm
• Tool type: impact-rated socket for use with impact wrenches
• Material: heat-treated/hardened steel designed for impact use
• Finish: impact-capable protective coating to resist corrosion and wear

How to use

Fit the 11 mm impact socket onto the 1/2" square drive of an appropriate impact wrench or breaker bar. Ensure the socket is fully seated on the drive and correctly aligned with the fastener before applying torque. Use suitable impact-rated extensions or adapters if additional reach or access is required. Inspect the socket for damage before use and replace it if any cracks, deformation, or excessive wear are present.

Usage recommendations

Use only with impact-rated tools and accessories; do not use impact sockets with hand ratchets or torque wrenches calibrated for hand tools when precise torque values are required. Store in a dry environment and clean sockets after use to extend service life.
