Westward 16 x 18 mm Box End Wrench
This double box end wrench fits 16 mm and 18 mm metric fasteners. The 10 in overall length gives leverage for automotive and maintenance tasks. Alloy steel construction with a satin finish resists corrosion during daily use. A 40 degree offset angle clears obstructions around the fastener head.
Check fastener size and clearance before ordering
Verify that the bolts or nuts you service are exactly 16 mm or 18 mm across the flats. Confirm the 40 degree offset and 10 in length can reach the fastener in your engine bay or machinery. The tether capable design suits jobs requiring tool retention at height. Ensure metric sizing matches your application.
Replaces worn or missing single size wrenches
This one tool covers two common metric sizes, reducing the number of pieces you carry. The offset box ends grip fastener corners more securely than open ends on rounded bolts. Upgrade when your current wrenches show rounding or when a tether point is required for safety compliance. The satin finish offers better grip than polished alternatives.
