Apex 80402 Spark Plug Socket 3/8 in Drive 6 Pt 5/8 in

Product Description

The APEX 80402 is a standard-length spark plug socket designed for 3/8 inch drive ratchets and breaker bars. It features a 6-point 5/8 inch opening sized for common spark plug hex sizes found in gasoline engines. Manufactured from alloy steel with a full-polish chrome finish, the socket resists rust and corrosion in shop and field conditions. The internal grip geometry is engineered to seat firmly on spark plug hex bodies, reducing slippage during removal and installation. At 0.22 pounds and 2.5 inches in length, it fits standard-depth spark plug wells without adapters in most applications.

This socket is used by automotive technicians, small-engine mechanics, and trade professionals performing spark plug service on gasoline-powered equipment. The 5/8 inch size is a common spec for passenger vehicles, light trucks, and many small-engine platforms. The standard length is suited for accessible plug locations where a deep-reach or swivel-style socket is not required. It pairs with any 3/8 inch drive ratchet, extension, or torque wrench already in a standard tool kit.

Key Features

• 3/8 inch drive for compatibility with standard ratchets, extensions, and torque wrenches
• 6-point 5/8 inch opening provides firm engagement on spark plug hex flats
• Alloy steel construction for durability under high-torque applications
• Full-polish chrome finish resists rust and corrosion
• Standard length at 2.5 inches suits accessible spark plug locations
• Lightweight at 0.22 pounds for easy single-hand use

Compatibility

Designed as a standard OEM-style spark plug socket for use with 3/8 inch drive hand tools on gasoline engines requiring a 5/8 inch spark plug socket.

Installation Notes

Spark plug service should be performed by a qualified mechanic with the engine off and ignition disabled. Allow the engine to cool fully before removing spark plugs to avoid thread damage in aluminum cylinder heads. Use a torque wrench on reinstallation — refer to the engine manufacturer's service manual for the correct torque specification. Never force a plug that does not thread freely, as cross-threading can damage the head.
