Yhdistelmäavain KS Tools 503.5917 17 mm kromi-vanadiiniteräs

The KS Tools 503.5917 17 mm combination wrench is a single-piece hand tool crafted from chromium‑vanadium steel. It combines an open-end and a boxed ring end in one tool and features a 15° offset angle to improve access in confined or recessed fastener locations. With an overall length of 225 mm and a compact weight, the wrench is intended for routine mechanical maintenance, assembly and repair tasks where a durable, accurate turning tool is required.

Advantages

The chromium‑vanadium steel construction provides strength and resistance to wear while preserving a slim profile for access to tight areas. The 15° offset on the ring end allows better clearance between the hand and the work surface, reducing interference when turning fasteners in narrow spaces. The single‑piece design ensures consistent torque transfer and reduces the risk of distortion under normal workshop loads. Its length balances leverage and reach for typical automotive, industrial and household applications.

Suitable for

• Automotive maintenance and repair
• Industrial assembly and machinery service
• Home DIY and furniture assembly
• Plumbing and HVAC fittings in constrained spaces

Key specifications

• Wrench type: combination (open end + boxed ring end)
• Nominal size: 17 mm
• Material: chromium‑vanadium steel
• Offset angle (ring end): 15°
• Overall length: 225 mm
• Weight: approximately 170 g
• Construction: single piece

How to use

Select the 17 mm end appropriate for the fastener type: use the open end for quick positioning and the boxed ring end for full-face engagement. Fit the wrench squarely onto the fastener to minimize rounding. When using the 15° offset ring end, orient the offset to provide the best clearance from nearby surfaces and allow progressive repositioning when space limits full rotation. Apply steady, controlled force and avoid sudden impacts or using the wrench as a hammer. For stubborn fasteners, use proper penetrating lubricant and ensure the tool is seated correctly before increasing torque.

Recommendations

Use the KS Tools 17 mm combination wrench in dry, clean conditions and inspect the tool before use for wear or deformation. Avoid excessive torque beyond hand tool limits and do not use cheater bars. Store the wrench in a tool tray or rack to prevent corrosion and protect the working edges for long service life.
