Combination Wrench Wera 05073281001

The Wera 05073281001 Combination Wrench is a high-quality imperial 3/8" tool made from chrome molybdenum steel with a nickel-chrome finish. At 159 mm length, this single-piece wrench combines an open-end with a ratcheting ring end and is suitable for hexagon socket screws, bolts and nuts in varied maintenance and mechanical tasks.

Advantages

This combination ratchet wrench features a replaceable metal plate in the jaw that securely holds nuts and bolts and reduces the risk of dropping them. The integrated limit stop and double-hex geometry provide a positive connection and reduce slippage while allowing higher torque transfer. The open end offers a small 30° return angle to minimise flipping, and the ring end contains an 80-tooth fine-tooth ratchet for use in confined spaces. Specially forged geometry ensures strength and reliable torque transmission, and the nickel-chrome coating improves corrosion resistance.

Suitable for

• Servicing and repair of imperial fasteners
• Automotive and motorcycle maintenance using 3/8" fittings
• General mechanical assembly and disassembly

How to use

Select the wrench for the correct 3/8" fastener, place the open end or ring over the bolt or nut and apply steady turning force. Use the ring end with the fine-tooth ratchet in confined spaces to avoid repositioning; the 80-tooth mechanism lets you work with small return angles. If needed, replace the metal plate in the jaw according to manufacturer guidance to maintain the holding function.

Usage recommendations

For safe and effective operation, ensure the wrench size matches the fastener precisely, avoid excessive impact forces, and keep the ratchet mechanism clean and lightly lubricated. Store the wrench dry to preserve the nickel-chrome coating.
