Milwaukee 3/8" Drive 5/8" 6-Point Spark Plug Socket 48-22-9550
PRECISION RETENTION FOR CRITICAL ENGINE SERVICE
Engineered to eliminate the risk of cracked porcelain and dropped plugs, this 6-point spark plug socket utilizes a dual-material rubber retainer that provides superior grip compared to standard magnetic or single-material inserts. The mechanical design focuses on control; precision knurling on the outer diameter allows for sensitive hand-starting of threads to prevent cross-threading in aluminum heads, while the external hex base permits the use of a wrench when vertical clearance prevents the use of a standard 3/8" ratchet. Built to withstand the caustic environment of a professional garage, the chrome finish and internal retainer are fully resistant to harsh automotive chemicals, ensuring long-term professional ROI.
- / Dual-material rubber retainer ensures a secure fit to prevent spark plug damage or accidental drops during extraction.
- / Precision outer knurling provides maximum grip for hand-tightening and loosening in oily environments.
- / Integrated external hex base allows for wrench-assisted torque in tight engine bays where ratchet swing is limited.
- / Large stamped size markings provide quick identification and resist wear from repeated chemical exposure.
- / 6-Point geometry optimizes contact with the plug hex to prevent rounding under high break-away torque.
