DOUBLE OPEN END SPANNER DIE (10-11)

The DE NEERS 10x11 mm Heavy Duty Double Open End Spanner is a professional-grade hand tool engineered for tightening and loosening rotary fasteners like nuts and bolts. Forged from high-grade Chrome Vanadium Steel (or Alloy Steel), it undergoes precision hardening and tempering to maximize strength and deliver an exceptionally long service life.

Key Technical Specifications

• Size: 10 x 11 mm (Metric)

• Material: Fully hardened and tempered Chrome Vanadium Steel (31 CrV3)

• Finish: Premium, scratch-resistant Satin/Chrome plating providing rust and moisture resistance

• Head Angle: Both jaw heads are set at a 15-degree angle to enable optimal accessibility in cramped or confined spaces

• Standards: Generally conforms to international industrial standards IS 2028-2004 and DIN 895

• Imperial Equivalent: Correspondingly matches the Whitworth standard size of 1/8 x 3/16 WW

Notable Design Features

• Raised Collar Profile: This "German Type" engineer's spanner configuration integrates a raised collar design to increase structural strength and absorb higher torque thresholds without deformation.

• Precision Ground Jaws: The jaw openings are ground precisely to the exact nominal dimension (10mm and 11mm), ensuring a secure, non-slip fastener fit that protects the bolt head corners from stripping.

• Ergonomic Handle: Built with an optimized elongated profile to comfortably maximize leverage during manual high-torque applications
