Tekton SHB13408 Long Hex Bit Socket 3/8 in Drive 8 Mm

Product Description

The TEKTON SHB13408 is a long hex bit socket designed for use with 3/8 inch drive ratchets, extensions, and torque wrenches. It accepts an 8 mm hex fastener and delivers a 5.9-inch overall length that provides clearance for recessed bolts, deep fastener pockets, and confined spaces where a standard-length socket cannot reach. The extra depth makes it well suited for machinery assembly, automotive work, and equipment maintenance where hex-head fasteners sit below surrounding surfaces. Mechanics, millwrights, and general service technicians are the primary users of this type of socket.

This socket fits into typical workshop, fleet maintenance, and field service toolkits. It is appropriate for both light-duty assembly tasks and repetitive fastening cycles on hex-head cap screws and bolts measuring 8 mm across flats. The 3/8 inch drive interface is a common size in professional hand-tool sets, meaning it pairs with a wide range of drive tools already found in most service trucks and shop benches. It is sold individually, making it a practical single-piece replacement or addition to an existing socket set.

Key Features

• 3/8 inch square drive interface works with standard ratchets, breaker bars, and torque wrenches
• 8 mm hex bit end fits hex-head cap screws and bolts used across automotive and industrial applications
• 5.9-inch overall length provides access to recessed or deeply set fasteners
• Long-reach design reduces the need for extensions in many deep-access situations

Compatibility

Designed as an OEM-style replacement or standalone addition compatible with 3/8 inch drive tool sets that require an 8 mm long hex bit socket.

Installation Notes

This socket is installed by hand technicians and mechanics using standard 3/8 inch drive equipment. Confirm the fastener hex size before applying torque to avoid rounding. Inspect the socket and drive tool for wear or cracks before use, and follow the fastener manufacturer torque specifications for the application. Do not use impact drivers unless the socket is rated for impact service.
