Adjustable spanner Irwin 10505488 — adjustable jaw up to 20 cm, blue/yellow, 331 g

The Irwin adjustable spanner model 10505488 is a single, versatile hand tool designed for gripping and turning nuts, bolts and fasteners of varying sizes. It features a movable adjustable jaw that opens to a maximum width of 20 cm and a compact, lightweight construction of approximately 331 g. The tool’s blue and yellow finish identifies it as part of Irwin’s hardware range and provides basic surface protection during normal use.

Advantages

The adjustable jaw allows rapid adaptation to different fastener sizes without swapping tools, reducing downtime during repair and maintenance work. At roughly 331 g the spanner is light enough for prolonged handheld use while retaining a solid feel for controlled torque application. The blue/yellow finish resists everyday wear and gives easy visual identification among other tools. The wide jaw capacity simplifies work on larger bolts and fittings that would not be accessible with fixed-size wrenches.

Suitable for

• General mechanical repairs and assembly
• Plumbing tasks involving pipe fittings and large nuts
• Building maintenance and light industrial work
• Home DIY projects requiring a single adjustable wrench

Key specifications

• Maximum jaw opening: 20 cm
• Weight: approximately 331 g
• Finish: blue and yellow surface coating
• Tool type: adjustable spanner / adjustable wrench with movable jaw
• Intended use: manual hand tool for turning nuts and bolts

How to use

Select the desired jaw opening by rotating the adjustment mechanism until the movable jaw contacts the fastener securely. Position the spanner so the fixed and movable jaws fully engage the nut or bolt flats, then apply steady force to turn, keeping the tool square to the fastener to minimize slippage. For best control, pull the spanner toward you rather than push when possible. After use, retract the jaw to a smaller opening for storage to protect the adjustment mechanism and surrounding tools.

Usage recommendations

Use the spanner within its jaw capacity and do not apply excessive impact or leverage beyond manual force; for higher torque requirements use a tool designed for that purpose. Keep the adjustment mechanism clean and occasionally apply light lubricant to maintain smooth operation. Inspect the jaws for wear before tasks where secure grip is critical.
