With two open heads, the Tolsen 15056 Double Open End Spanner 16x17 mm turns metric fasteners in mechanical assemblies. Drop-forged chrome vanadium steel prevents tool deformation during high-torque applications. The 15-degree head angle grants access to recessed bolts where straight wrenches fail.
Key Features
- Chrome Vanadium Steel: Hardened Cr-V alloy prevents jaw deformation under heavy load. Resists snapping during high-torque mechanical repairs.
- 15-Degree Offset: Angled open ends permit fastener rotation in narrow spaces. Reaches bolts blocked by surrounding engine components.
- Anti-corrosion Finish: Satin matte coating blocks moisture from reacting with the steel. Stops rust formation during high humidity.
- Standardized Sizing: DIN3113 compliant jaws fit 16mm and 17mm bolt heads exactly. Prevents rounding of fastener edges.
