Socket set, impact deep sockets 3/4" drive, JCB, 14-piece hex (17–65 mm)

Deep impact socket set with 3/4" drive from JCB, containing 14 hex (6-point) deep sockets in sizes 17–65 mm. The set is designed for heavy-duty fastening and loosening with impact wrenches and other high-torque tools. Deep socket lengths provide access to recessed nuts and studs while the 6-point geometry reduces rounding on large fasteners commonly found in automotive, agricultural and industrial maintenance.

Advantages

The sockets are manufactured for impact use and are heat-treated to withstand repeated high-torque operations. A 3/4" drive interfaces with a wide range of impact wrenches and breaker bars, and the deep design enables secure engagement with long studs and recessed fasteners. The 6-point hex profile concentrates contact on flats to reduce slipping and damage under heavy load. The set covers common large metric sizes from 17 mm up to 65 mm, allowing a single kit to serve multiple maintenance tasks.

Suitable for

• Heavy vehicle and truck wheel and axle maintenance
• Agricultural machinery repair and field service
• Industrial equipment assembly and disassembly
• Workshop use with impact wrenches and pneumatic tools
• Maintenance of construction and earth-moving machinery

How to use

Select the socket that matches the fastener size, ensure the impact tool is set to the appropriate torque or air pressure for the application, and secure the socket on the 3/4" drive. Fit the socket fully onto the nut or bolt head to ensure correct engagement before applying impact force. For removal or installation on long studs or recessed nuts, use the deep socket to reach the fastener while maintaining steady alignment to prevent cross-threading or rounding. After use, wipe sockets clean and store the set to prevent corrosion and loss.

Usage recommendations

Use only with impact-rated tools and accessories; do not use impact sockets with hand-only ratchets unless specified safe by the manufacturer. Match socket size precisely to fastener, avoid excessive torque beyond the tool and fastener ratings, and inspect sockets regularly for cracks or deformation. For prolonged service life, clean and lightly oil sockets before storage and avoid exposure to corrosive environments.
