Adjustable wrench BAHCO 3850-13-0.6-14/18 — 13 mm jaw width, adjustable opening

BAHCO 3850-13-0.6-14/18 is an adjustable wrench with a 13 mm jaw width designed for gripping and turning fasteners of matching size. The tool provides an adjustable opening to accommodate a range of workpieces within its capacity and is intended for assembly, maintenance and repair tasks where precise adjustment and reliable clamping are required. The construction follows BAHCO's standards for durability and everyday usability.

Advantages

The wrench combines a compact jaw width with a smoothly adjustable mechanism that enables accurate positioning on nuts and bolts. Hardened contact surfaces improve wear resistance while the ergonomic handle profile supports steady grip during torque application. The adjustable opening reduces the need to carry multiple fixed-size tools and allows quick adaptation to slightly different fastener sizes.

Suitable for

• Light to medium assembly and disassembly of 13 mm fasteners
• Maintenance and repair tasks in workshop and field environments
• Plumbing, HVAC and general household repairs requiring adjustable gripping
• Situations where a single adjustable tool replaces several open-end wrenches

Key specifications

• Jaw width: 13 mm
• Adjustable opening for a range of fastener sizes around 13 mm
• Material: heat-treated steel for improved durability
• Surface finish: corrosion-resistant treatment (factory-applied)
• Ergonomic handle shape for enhanced control

How to use

Select the wrench and open the jaw by turning the adjustment mechanism until the jaws clear the fastener. Position the jaws squarely on the nut or bolt head and tighten the adjustment so the tool grips without play. Apply steady torque in the required direction, maintaining a straight pull to minimize slippage. After use, release the adjustment slightly and store the wrench in a dry place to preserve the finish and mechanism.

Usage recommendations

Use the wrench within its jaw capacity to avoid rounding fasteners; avoid using the tool as a hammer or for prying. Regularly inspect the adjustment threads and contact surfaces for wear and remove debris to maintain smooth operation. For stubborn or corroded fasteners, apply penetrating lubricant and allow it to work before applying high torque.
