140 Non Sparking Single Open End Wrench

German standard DIN894 is adopted as basis for the design of 140 spark-proof single open-end wrench. To withstand rotational torque, the jaw is designed with stiffening ribs to increase its tensile strength. Non-sparking feature reduces the risk of fire or explosion that results from intense friction between the gripping face and fastener surface.

This wrench fits hex or square heads of nuts or bolts. Its jaw face offsets 15 degree from the line of the handle. This allows a wider range of movement within the tight spaces. The product is made of copper alloy that has undergone drop forging process to obtain high tensile strength, stable mechanical property, and long service life.
