Combination wrench AWTools AW39790, 500 g weight, closed and open ends

AWTools AW39790 is a combination wrench with one open end and one closed (ring) end, weighing approximately 500 g. Manufactured from chrome-vanadium (CrV) tool steel, the spanner is drop forged, hardened and tempered to meet durability requirements for general mechanical and maintenance work. The satin finish reduces slippage and the ring end is angled at 15° to provide improved accessibility on flat or crowded surfaces. Clear size markings make identification fast during repeated use and the design complies with DIN 3113 standard.

Advantages

The dual-end configuration gives both the quick engagement of an open-ended spanner and the secure grip of a ring end, enabling efficient turning, fastening and loosening of nuts and bolts. Chrome-vanadium construction and heat treatment ensure high strength and wear resistance, while the satin finish minimizes glare and hand slippage. The 15° ring end angle increases reach and allows work in tighter spaces without repositioning the tool frequently.

Suitable for

• General mechanical repairs and assembly work
• Automotive maintenance and light vehicle repairs
• Workshop and garage tasks requiring both open and ring ends
• Construction site fastening and on-site maintenance
• Hobbyist and professional toolkits for manual tightening and positioning

How to use

Select the correct size on the AWTools AW39790 by matching the clear size marking to the fastener. Use the open end for quick placement and initial turning where clearance is sufficient, and switch to the ring end for a more secure grip when final tightening or loosening is required. The 15° angled ring end can be used to access fasteners on flat surfaces or where a slight offset helps avoid obstruction. Apply steady force along the wrench axis and avoid sudden jerks to reduce the risk of rounding fasteners.

Usage recommendations

For safe and long-lasting performance, keep the wrench clean and dry after use, avoid striking the tool with hammers, and store it in a tool roll or toolbox to prevent corrosion and damage to the satin finish. Use the correct size to minimize wear on fasteners and the tool itself.
