Combination Wrench Wera 05073283001

The Wera 05073283001 combination ratchet wrench is a high-quality imperial tool designed for working with hexagon socket screws, bolts and nuts. It combines an open-end and a ratchet ring in one unit, available in 25 mm and 27 mm sizes plus a 1/2" imperial size. The wrench is forged from chrome molybdenum steel with a nickel-chrome coating for enhanced corrosion resistance and measures approximately 255 mm in length.

Advantages

This Wera wrench offers a replaceable metal plate in the jaw that holds nuts and bolts securely with extra-hard teeth, reducing the risk of dropping or slipping. An integrated limit stop prevents slipping around the bolt head and allows application of higher torque. The double-hex geometry provides a positive connection to fasteners, and the open end requires only a 30° return angle to continue turning without frequent repositioning. The ring end contains an 80-tooth fine-tooth ratchet mechanism for reliable operation in confined spaces. Colour coding on the tool finder aids quick size identification.

Suitable for

• Tightening and loosening hexagon bolts and nuts (25 mm, 27 mm, 1/2").
• Work in confined or hard-to-reach spaces where a fine-tooth ratchet is needed.
• Maintenance, mechanical assembly and general workshop tasks requiring a durable combination wrench.

How to use

Place the open end or ring end of the wrench onto the fastener corresponding to the selected size. Use the holding function of the jaw plate to retain nuts or bolts during positioning. For confined spaces, use the ring end with the fine-tooth ratchet to apply torque with minimal swing; the 30° return angle at the open end reduces the need to flip the wrench. Apply steady force aligned with the wrench axis and avoid sudden impacts to preserve the ratchet mechanism and the replaceable plate.

Usage recommendations

Periodic inspection and replacement of the jaw's metal plate will maintain holding performance. Keep the tool clean and lightly lubricate the ratchet mechanism if it becomes stiff. Use the correct size (25 mm, 27 mm or 1/2") to avoid rounding fasteners and do not exceed the torque limits typical for hand tools.
