Adjustable spanner Wera 05020176001 Jaw width 1.6 cm Steel

The Wera adjustable spanner 05020176001 is a compact steel tool with a maximum jaw width of 1.6 cm and an overall length of 65 mm. Designed for adjustable grip on hexagonal and square fasteners, this small spanner provides precise contact on nuts and bolts in confined spaces. The steel construction ensures basic durability and resistance to normal workshop wear while the narrow head and short length allow access where larger wrenches will not fit.

Advantages

This adjustable spanner combines a minimal footprint with adjustable jaw capability, enabling a single tool to fit a range of fastener sizes up to 1.6 cm. The steel build offers mechanical strength for routine tightening and loosening tasks. Its compact 65 mm length reduces leverage-related over-torque risk in delicate applications and makes the tool easy to store in small tool kits or pockets.

Suitable for

• Maintenance and repair work in tight or confined spaces
• Assembly and disassembly of small machinery, electronics enclosures, and bicycle components
• Portable tool kits for field service or on-site adjustments
• Hobbyist tasks requiring a compact adjustable wrench

Key specifications

• Maximum jaw width: 1.6 cm
• Material: steel
• Overall length: 65 mm
• Adjustable jaw for multiple fastener sizes
• Compact, narrow head for access in confined areas

How to use

Select the spanner and open the adjustable jaw to slightly exceed the fastener width. Position the jaws squarely on the nut or bolt head, then tighten the adjustment until the fit is snug without play. Apply steady torque with controlled force; avoid sudden impacts or excessive force that could damage the fastener or tool. After use, clean any debris or grease and store the spanner in a dry place to minimize corrosion.

Recommendations

Use the spanner for light- to medium-duty tightening and loosening tasks within the specified jaw range. For high-torque applications or larger fasteners, select a appropriately sized wrench to avoid damaging the tool or fastener. Regularly inspect the adjustable mechanism for wear and keep the moving parts lightly lubricated for smooth operation.
