Adjustable spanner Wera 05020177001 Jaw width 1.9 cm Steel

The Wera adjustable spanner with a jaw width of 1.9 cm is a compact, steel hand tool designed for precise tightening and loosening of fasteners in confined spaces. At 80 mm in length and weighing 147 g, it offers a balance of control and portability for light to medium-duty tasks. The single-piece steel construction provides rigidity and consistent jaw alignment for reliable grip on nuts and bolts.

Advantages

This adjustable spanner delivers a narrow jaw profile for work in tight spaces and on small fasteners. The steel construction ensures durability and wear resistance, while the compact length improves access where longer wrenches would be obstructive. Its lightweight design reduces hand fatigue during repeated use and the finely machined adjusting mechanism enables accurate jaw setting and secure clamping.

Suitable for

• Tight-space fastening and maintenance work
• Adjustment of small nuts and bolts in machinery and equipment
• Electronics and appliance assembly where compact tools are required
• General workshop and field service tasks requiring a compact adjustable wrench

Key specifications

• Maximum jaw width: 1.9 cm
• Material: steel
• Overall length: 80 mm
• Weight: 147 g
• Adjustable jaw for multiple fastener sizes

How to use

Select the Wera adjustable spanner and turn the adjusting mechanism until the jaw opening matches the fastener size. Position the fixed jaw side against the stationary surface and place the movable jaw firmly against the fastener. Apply steady torque while keeping the spanner aligned with the fastener axis to minimize slippage and avoid damaging the fastener edges. After use, retract the jaw to a compact position and store the tool in a toolbox or pouch to protect the adjusting mechanism and finish.

Recommendations

For best results, use this compact adjustable spanner on small to medium fasteners where access is limited. Avoid excessive force beyond the intended light to medium-duty range to prevent deforming the jaws. Regularly clean and lightly lubricate the adjusting mechanism to maintain smooth operation and inspect the jaw surfaces for wear before critical tasks.
