Rengasavain KS Tools 503.4678 124,5 mm

The ks tools Ring Wrench 503.4678 with a length of 124.5 mm is a hand tool designed for precise turning of fasteners in confined spaces. Its compact size provides controlled leverage and access where larger tools cannot reach. The wrench is intended to deliver consistent contact with bolt or nut heads to reduce rounding and improve torque transmission during assembly and maintenance tasks.

Advantages

The ring profile offers full-circumference engagement with fastener heads for improved grip and reduced slippage. A length of 124.5 mm balances reach and control, making the tool suitable for both tight spots and applications that require steady torque. Manufactured to industry-grade tolerances, the wrench is designed for repeated professional use and maintains its geometry under normal workshop conditions.

Suitable for

• Automotive repair and maintenance in confined engine or suspension areas
• Mechanical assembly and disassembly where compact tools are required
• Plumbing or HVAC tasks involving recessed fasteners
• General workshop and DIY projects requiring precise torque application

Key specifications

• Tool type: ring wrench
• Length: 124.5 mm
• Material: hardened alloy steel (industry standard)
• Profile: full ring (box end) for 12-point or 6-point fasteners depending on model fit
• Finish: corrosion-resistant surface treatment
• Hand orientation: single-piece solid construction for manual use

How to use

Select the correctly sized ring wrench for the fastener to ensure full engagement with the nut or bolt head. Slide the ring end over the fastener and position the tool so the ring fully seats onto the flats of the fastener. Apply steady, controlled force in the required direction, avoiding sudden impacts. For loosening seized fasteners, apply penetrating lubricant first and use incremental force to avoid rounding the fastener edges. After use, wipe the tool clean and store it in a dry location to preserve the finish.

Recommendations

Use the ring wrench only on fasteners that match the tool size to prevent damage. Do not use the tool as a hammer or pry bar. Inspect the wrench periodically for wear, distortion, or surface corrosion and replace if the ring profile is deformed or excessively worn.
