Wrenches, adjustable, ERGO, center nut, rubber handle, phosphated Adjustable wrenches developed according to the scientific ERGO™ process Jaws will not fall out, even at maximum opening of the wrench The head combines a narrow design for better access with strength, for the best performance Laser scale in mm for adjustment and accurate measurements Rubber handle resistant to Skydrol and oil High-quality one-piece steel alloy Phosphate finish, precision hardened and anti-corrosion treatment Counter-clockwise screw Standards: ISO 6787, DIN 3117, ASME B107.8-2003 and BS 6333 Maximum comfort with minimum effort due to the ergonomic design The ergonomically designed thermoplastic elastomer handle distributes pressure evenly across the hand, reducing the risk of work-related injuries The handle never feels too hot or too cold, and is resistant to oil and grease. Soft surface with a lot of friction, less chance of slipping Parallel jaws at an angle of 15° for a firm grip and the best reach Very strong thanks to precision hardening and high-quality steel alloy
