Wrench JCB offset combination wrench 75° 17 mm, JCB JCB-75517A

Offset combination wrench JCB 75° 17 mm is a hand tool designed for fastening and loosening nuts and bolts where angled access is required. One end features a 17 mm open jaw for quick engagement, while the opposite end has a 12-point ring (box) head set at a 75° offset to reach fasteners in confined or recessed spaces. The tool is intended for maintenance, repair and assembly tasks in automotive, agricultural and light industrial environments.

Advantages

The 75° offset provides improved clearance between the user’s hand and the work surface, allowing access to fasteners in tight locations without the need to remove adjacent components. Combining an open-end and a ring end in a single tool reduces the number of tools required on the job and speeds up switching between grip types. The ring end’s 12-point geometry permits more engagement positions on the fastener, enabling small-angle ratcheting movement where space is limited.

Suitable for

• Automotive maintenance and repair where angled wrenches are needed
• Agricultural and construction equipment service with recessed fasteners
• General mechanical assembly and workshop tasks requiring 17 mm drive size
• Situations demanding quick alternation between open and ring contact

Key specifications

• Wrench type: offset combination wrench (open end + ring end)
• Offset angle: 75°
• Size: 17 mm
• Ring geometry: 12-point box end
• Hand tool application: manual fastening and loosening of bolts and nuts

How to use

Select the 17 mm offset combination wrench for fasteners matching the size. Position the open jaw over the nut or bolt head for initial loosening or when side access is required, or fit the ring end fully over the fastener for improved contact and torque transfer. Use steady manual force and maintain alignment to avoid rounding the fastener. The 75° offset helps keep knuckles and hands clear of adjacent surfaces; turn the wrench within comfortable arcs and reposition as needed to complete the operation.

Usage recommendations

Inspect the wrench for damage or excessive wear before use. Use only on correctly sized fasteners and avoid applying impact force with the wrench. For higher torque requirements, consider using a longer leverage tool or a torque-rated device. Store the tool in a dry place to prevent corrosion and periodically clean and lightly lubricate to maintain smooth use.
