Beta Tools Combination Wrench 42AS Open and Offset Ring Inch
Made from high-strength alloy steel, the 42AS combination wrench family pairs an open fork with an offset ring end for improved access in confined spaces. The ring and fork are inclined 15° to reduce the pick-up angle and facilitate grip where clearance is limited; fork thicknesses are minimised for easier intervention. Extended wrench lengths increase torque with less effort across the inch-size range, suited for automotive, industrial maintenance and mechanical workshops. Each SKU in the 42AS range (for example SKU 000421106 = 1/4") corresponds to a specific inch size and documented dimensions; consult the size-specific variant when selecting the correct opening.
Specifications
