Combination wrench AWTools AW39788, size unspecified, steel, weight 470 g

AWTools AW39788 is a combination wrench crafted from chrome-vanadium (CrV) tool steel, featuring an open-end on one side and a ring end on the other. The body is drop forged, hardened and tempered to provide consistent strength and durability for general mechanical work, repairs and maintenance. A satin finish reduces slippage while clear size markings enable quick identification. The ring end is angled at 15° to improve accessibility on flat surfaces and tight spaces. The tool complies with DIN 3113 standard and weighs approximately 470 g.

Advantages

The AWTools AW39788 combines an open-ended spanner and a ring spanner in a single forged piece, offering both versatility and robustness. Chrome-vanadium construction and heat treatment provide high tensile strength and wear resistance while the satin finish improves grip and reduces glare. The 15° angled ring end enhances usability on recessed or flush fasteners, and clear engraved size markings make the tool easy to select during work. Conformance to DIN 3113 ensures dimensional accuracy and interchangeability with standardized fasteners.

How to use

Select the correct size by reading the clear size markings and position the appropriate end over the nut or bolt head. Use the open end for quick placement and the ring end for a firmer grip when higher torque is needed. The 15° angled ring end is useful for accessing fasteners on flat or recessed surfaces; angle the wrench accordingly to gain clearance. Apply steady, controlled force and avoid sudden impacts. After use, clean the wrench of dirt and residues and store it in a dry place to prevent corrosion.

Usage recommendations

Use the AWTools AW39788 for tasks suited to its size and strength; avoid applying excessive torque beyond the tool's capacity or using the wrench as a hammer or lever. Regular inspection for wear or deformation and periodic cleaning will prolong service life. For working on fasteners requiring precise torque values, combine this wrench with a calibrated torque wrench to ensure accurate tightening.
