Socket bit (deep) JCB 3/4" 38 mm 12-point

Deep socket for 3/4" drive, JCB 38 mm with a 12-point internal profile designed to access recessed nuts and bolts. This JCB socket provides extended reach compared with standard shallow sockets and is intended for professional repair and maintenance tasks in automotive, industrial and construction environments. The deep design allows users to work with fasteners located on long studs or within recessed housings while maintaining a solid 12-point engagement to reduce rounding of heads.

Advantages

The deep construction increases clearance for long studs and recessed fasteners while preserving torque transfer through a 12-point contact geometry. Made to fit a 3/4" drive, the socket offers improved access in tight or deep locations and helps maintain secure engagement on twelve-point bolts and nuts. The alloy steel construction and precise internal profile support consistent fit and wear resistance under repeated professional use.

Suitable for

• Automotive repair and wheel hub, axle or suspension fasteners
• Industrial maintenance where nuts are recessed on long studs
• Construction equipment servicing and assembly
• Professional workshop and field service operations requiring extended-reach sockets

Key specifications

• Drive size: 3/4"
• Socket size: 38 mm
• Internal profile: 12-point
• Type: deep/socket with extended length
• Intended use: nuts and bolts on long studs or recessed fittings

How to use

Select the 38 mm 12-point deep socket and attach it to a compatible 3/4" drive ratchet, breaker bar or torque wrench. Position the socket squarely onto the fastener and apply steady torque, ensuring full engagement of the 12 points to minimize rounding. For removal of seized fasteners use a breaker bar to apply controlled force; when tightening, follow the torque specifications provided for the application. Inspect the socket for wear or damage before use and replace if deformation or excessive wear is present.

Usage recommendations

Use with appropriate hand tools rated for 3/4" drive and observe manufacturer torque limits. Avoid impact tools unless the socket is specifically rated for impact use. Store in a dry place and clean after use to prolong service life.
