## Long description

STANLEY 4-89-937 is a 12 mm combination wrench made from stainless steel, designed to provide a reliable single-size solution for fastening and loosening bolts and nuts. The tool combines an open-end jaw and a boxed (ring) end to access fasteners in different positions. Its compact form and corrosion-resistant material make it suitable for environments where a durable fixed-size hand tool is required.
Advantages
The stainless steel construction offers corrosion resistance and extended service life compared with untreated steel. The open-end side allows quick engagement on flats while the boxed end provides a more secure grip for higher torque applications. The compact length and slim profile enable access in tighter spaces, and the single fixed size eliminates the need for adjustment, providing consistent performance during repetitive tasks.
Suitable for
Automotive repair and maintenance
General mechanical assembly and disassembly
Household repairs and DIY projects requiring a fixed 12 mm wrench
Maintenance work in workshops and service facilities
Key specifications
Tool type: Combination wrench (open-end and boxed end)
Size: 12 mm
Material: Stainless steel for improved corrosion resistance
Ends: Open jaw and 12 mm boxed (ring) end for secure engagement
Form factor: Fixed-size hand tool with compact profile
How to use
Select the 12 mm combination wrench when the fastener size matches the tool. Position the open-end jaw over the flats of the nut or bolt for quick turning or use the boxed end to engage the fastener fully for higher torque and reduced slippage. Apply steady pressure and avoid sudden impacts; use the boxed end for final tightening or initial loosening where possible. Keep the wrench aligned with the fastener axis to reduce rounding of corners.
Usage recommendations
Inspect the wrench before use for any deformation or wear. Clean and dry the tool after exposure to moisture to preserve the stainless steel finish. Do not use the wrench with an extension or as a hammer; use the appropriate tool for impact or higher torque applications. For safe operation, pair the wrench with correctly sized fasteners and use proper hand protection when necessary.
