Open-End and Ring Wrench 20mm STANLEY 1-87-080

The STANLEY Open-End and Ring Wrench 20mm (model 1-87-080) is a single-size hand tool designed for turning 20 mm nuts and bolts. One end features a standard open jaw for quick slip-on access, while the opposite end has a closed ring that provides full contact around the fastener for higher torque and reduced rounding. The wrench is intended for general mechanical, automotive and maintenance work where a reliable 20 mm spanner is needed.

Advantages

The combination of open-end and ring-end gives flexibility for different work situations: the open end allows rapid engagement on partially obstructed fasteners, and the ring end delivers secure grip for tightening or loosening under higher loads. The single-size format simplifies tool selection when working specifically with 20 mm fasteners. Durable construction and a solid profile provide stability during use and help resist deformation under normal workshop conditions.

Suitable for

• Automotive repair and maintenance involving 20 mm nuts and bolts
• General mechanical assembly and disassembly tasks
• Home and workshop maintenance where a dedicated 20 mm wrench is required
• Professional trades needing a reliable single-size spanner for repetitive jobs

Key specifications

• Working size: 20 mm
• Configuration: open-end on one side, ring/closed end on the other
• Single-size combination wrench designed for hand use
• Intended applications: tightening and loosening nuts and bolts

How to use

Select the wrench and align the open or ring end with a 20 mm fastener. For quick placement where access is limited, engage the open end and apply controlled force. For higher torque or to minimize rounding of the fastener, fit the ring end fully around the nut or bolt head before applying force. Apply steady pressure and avoid sudden impacts; use the correct hand positioning to maintain control and reduce risk of slippage.

Usage recommendations

Inspect the wrench before use for signs of wear, deformation or damage. Use the ring end for final tightening or loosening under higher torque to protect fastener corners, and avoid using the wrench as a hammer or pry bar. Store the tool in a dry place to prevent corrosion and maintain accuracy when working with 20 mm fasteners.
