Designed to help you remove or tighten fasteners that are very tightly wound, this Taparia Single Sided Box End Wrench has a short and tough body. The thick end of this tool allows you to apply force on the tool with a hammer when you need extra torque. The inner circumference of this slugging ring spanner is notched to help you get better grip on the fastener. So, you can turn fasteners without slippage and complete your work faster and efficiently. The compact size of this tool also lets you use it in tight spaces where you need greater hand movement.
