Combination wrench Proline 35457, 17 mm, 230 mm length, single piece

The Proline combination wrench 35457 is a single-piece, 17 mm spanner with a total length of 230 mm designed for general mechanical and maintenance tasks. It features an open-end on one side and a 12-point ring on the other, offering versatility when tightening and loosening nuts and bolts. The tool is forged for strength, chrome-plated for corrosion resistance and finished with a satin surface to reduce glare and improve grip during use. The ring end rotates on a joint with a range of motion of ±90°, allowing access in confined spaces while maintaining a functional minimum work angle of 5°.

Advantages

The forged construction provides improved durability and resistance to bending under torque. Chromium plating enhances corrosion resistance and simplifies cleaning after use. The satin finish reduces surface reflections and helps maintain a secure hold. The combination of an open-end and a ring end makes the wrench adaptable to a range of fastener types and positions, while the articulated ring end increases access to hard-to-reach bolts without requiring multiple tools.

Suitable for

• Automotive repair and routine vehicle maintenance
• Industrial assembly and machinery maintenance
• Plumbing and home repair tasks involving 17 mm fasteners
• Situations requiring access in limited or awkward spaces

Key specifications

• Size: 17 mm working jaw/ring size
• Overall length: 230 mm
• Construction: forged single-piece design
• Surface: chromium-plated with satin finish
• Ring end: 12-point configuration on a joint with ±90° range of motion
• Minimum working angle: 5°

How to use

Select the 17 mm opening to match the fastener head and position either the open-end or the ring end as appropriate. For maximum torque and reduced risk of rounding fasteners, use the ring end when possible. Employ the jointed ring end to approach bolts at an angle or in constrained spaces; rotate the joint within its ±90° range to align the ring with the fastener. Apply steady force and avoid sudden impact loads. After use, wipe the chrome-plated surface clean and store the wrench to prevent corrosion and mechanical damage.

Usage recommendations

Use the ring end on 12-point fasteners for secure seating and the open-end where quick engagement or side access is required. Avoid applying excessive force beyond typical hand-torque limits and do not use the wrench as a hammer or pry bar. Regularly inspect the tool for wear, especially at the jaws and joint, and maintain the satin chrome finish by keeping the wrench clean and dry.
