Milwaukee 3/8" Drive 18mm 6-Point Spark Plug Socket 48-22-9556
ENGINEERED FOR PRECISION AND PLUG PROTECTION
The Milwaukee 3/8" Drive 18mm 6-Point Spark Plug Socket is a masterclass in mechanical design, addressing the common failure points of standard automotive sockets. Featuring a specialized dual-material rubber retainer, this socket provides a high-friction grip that prevents spark plugs from slipping or sustaining ceramic damage during extraction. The exterior is finished with precision knurling for maximum tactile control during hand-tightening, while the base incorporates an external hex for wrench-assisted torque in tight engine bays where ratchet clearance is limited.
- / Dual-Material Rubber Retainer ensures a secure fit to prevent dropping or cracking delicate spark plug insulators.
- / Precision Knurled Surface provides enhanced grip for oily hands when starting threads or loosening by hand.
- / External Hex Base allows for the use of a 20mm wrench, offering a low-profile alternative to traditional ratchets.
- / Stamped Size Markings provide permanent visibility that won't wear off after exposure to harsh garage chemicals.
- / Chrome Plated Finish delivers superior rust protection and long-term professional ROI.
