With a dual-head configuration, the Tolsen 15028 Combination Spanner 20mm grips 20mm fasteners. Chrome Vanadium steel maintains a 42-48 HRC hardness for high-torque mechanical workshop tasks. Under heavy pressure, the DIN 3113 standard construction prevents structural bending.
Key Features
- Chrome Vanadium Steel: Drop forged Cr-V metal with 42-48 HRC hardness rating. Hardened metal resists jaw spread during heavy industrial fastening.
- 12-Point Box End: 12-point geometry for increased contact with the fastener surface. Grip prevents rounding off nut and bolt corners.
- 15° Offset Angle: Box end tilts at 15-degrees from the tool handle. Provides knuckle clearance when working against flat plates.
- Satin Chrome Finish: Matte-finish coating compliant with DIN 3113 corrosion standards. Blocks oxidation from workshop moisture and chemicals.
- Drop Forged Construction: Manufacturing process aligning metal grain for structural integrity. Tool won't snap under sudden high-impact torque loads.
Frequently Asked Questions
What is the material of Tolsen 15028?
Chrome Vanadium steel hardened to 42-48 HRC forms this wrench. This alloy resists deformation under extreme industrial torque.
Is Tolsen 20mm spanner rust resistant?
Satin chrome finishes create a physical barrier against moisture. This coating prevents rust during humid storage conditions in Bangladesh.
