Wrench Proline 9033142 20x22 mm CrV curved open-end

Curved open-end wrench Proline 9033142, size 20 x 22 mm, made from chrome vanadium (CrV) steel. This angled open-end wrench is cold-forged and chrome-plated for corrosion protection and increased durability. It is designed for tightening and loosening nuts and bolts in confined or angled spaces where a straight wrench is impractical and meets DIN 838 standards.

Advantages

The Proline 9033142 combines cold-forged CrV construction with chrome plating to provide strength, wear resistance and protection against corrosion. Its curved, angled open ends allow better access in tight or awkward spaces compared with a straight wrench. Manufactured to DIN 838, it ensures consistent dimensions and reliable fit on 20 mm and 22 mm fasteners.

Suitable for

• Automotive repair and maintenance
• Workshop and garage tasks
• Assembly and repair in confined or angled spaces
• General maintenance involving 20 mm and 22 mm nuts and bolts

How to use

Select the correct end (20 mm or 22 mm) to match the nut or bolt head. Place the curved open end over the fastener so the wrench sits fully on the flats, then apply steady force in the required direction to tighten or loosen. The angled design helps reach fasteners in restricted areas; position your body and hands to maintain control and avoid slipping. Inspect the wrench before use to ensure the chrome plating and jaws are intact.

Usage recommendations

For best results, use the Proline curved open-end wrench on correctly sized hexagonal fasteners and avoid excessive torque that could damage the fastener or tool. Store in a dry place to preserve chrome plating and prevent corrosion.
