The KS Tools 503.5914 combination wrench is made from chromium‑vanadium steel and designed for reliable tightening and loosening of nuts and bolts. It has an open end with an innovative ratchet mechanism and a 15° offset jaw and ring head. The tool conforms to DIN 3113 / ISO 3318 standards and features a FlankTraction profile, exact 72‑tooth gearing and a high‑quality chrome finish. At 14 mm size, 191 mm length and approximately 100 g weight, it is compact and easy to handle for a variety of workshop tasks.

Advantages

The ratchet mechanism in the open end permits continuous turning without repositioning, while the 72‑tooth gearing provides fine engagement for work in confined spaces. FlankTraction profile reduces risk of rounding fasteners and improves torque transmission. Chromium‑vanadium construction and chrome finish ensure durability and corrosion resistance. The reversing lever allows quick switching between tightening and loosening.

How to use

Place the appropriate end of the wrench on the fastener and apply steady force in the required direction.

Store the wrench clean and dry after use to maintain the chrome finish and prevent corrosion.

Recommendations

Use the wrench within its intended size (14 mm) and avoid applying excessive impact or leverage beyond hand force to prevent tool damage. Regularly inspect the FlankTraction surfaces and ratchet mechanism for wear and clean before storage.
