Proto J5326HPA Spark Plug Hand Socket 13/16 in 6-point

Product Description

The PROTO J5326HPA is a 13/16 inch spark plug hand socket designed for removing and installing spark plugs in engine service applications. It features a 1/2 inch square drive and a 6-point contact geometry that reduces the risk of rounding fasteners during high-torque removal. The socket carries a chrome-plated finish that resists corrosion and makes cleanup easier after use. At 0.35 pounds and compact dimensions, it is a practical addition to any ignition service kit used by automotive technicians, HVAC technicians servicing gas-engine equipment, or small-engine mechanics.

This socket is suited for spark plug service on gasoline-powered equipment where a 13/16 inch plug hex is standard. Typical applications include passenger vehicle engines, light trucks, small-engine outdoor power equipment, and engine-driven HVAC or generator units. The 1/2 inch drive pairs with standard ratchets, breaker bars, and torque wrenches commonly found in professional service environments. The 6-point design is preferred over 12-point sockets in spark plug work because it delivers full-face contact on the plug hex, minimizing cam-out under load.

Key Features

• 13/16 inch socket size fits standard spark plug hex dimensions
• 1/2 inch square drive compatible with common ratchets and torque wrenches
• 6-point geometry provides full-face contact and reduces fastener rounding
• Chrome-plated finish resists corrosion and simplifies cleaning
• Compact form factor at 2.7 inches length for use in tighter engine bays

Compatibility

Designed as an OEM-style hand socket for use with 13/16 inch spark plug hex fasteners on 1/2 inch drive tool sets in professional service applications.

Installation Notes

Spark plug service should be performed only on a cool engine to avoid thread galling and burn hazards. Disconnect the ignition system and, where applicable, the battery before removing plugs. Use a calibrated torque wrench on reinstallation to avoid over-tightening the plug into the cylinder head. This socket is intended for hand-tool use with a 1/2 inch drive ratchet or breaker bar.
