About Spanners

Spanners are essential hand tools found in every professional tradesperson's toolkit and DIY enthusiast's workshop. From basic open-ended and ring spanners to specialised box spanners designed for specific applications, these versatile tools provide the mechanical advantage needed to tighten and loosen nuts and bolts across countless tasks. MyToolShed.co.uk stocks a carefully selected range of quality spanners to meet the demands of both professional and home use.

Whether you're working on automotive repairs, machinery maintenance, plumbing installations, or garden equipment servicing, having the correct spanner for the job ensures efficient work and prevents damage to fasteners. Box spanners, in particular, offer excellent access in confined spaces where standard spanners cannot reach, making them invaluable for tasks such as lawnmower maintenance and equipment assembly.

Applications

• Automotive mechanics - engine repairs, brake systems, and general vehicle maintenance
• Plumbers and heating engineers - pipework installation and radiator fitting
• General builders and maintenance teams - structural steelwork and equipment installation
• Agricultural and groundcare professionals - farm machinery and garden equipment servicing

Choosing The Right Spanners

When selecting spanners from MyToolShed.co.uk, consider the following factors:

• Size and fitting - Always match the spanner size precisely to the nut or bolt to prevent rounding and damage. Common UK sizes range from 6mm to 32mm for metric fasteners
• Type of spanner - Box spanners excel in confined spaces, combination spanners offer versatility, whilst adjustable spanners provide multi-size functionality
• Material quality - Chrome vanadium steel offers excellent strength and durability for professional use
• Application-specific designs - Specialist spanners like spark plug box spanners are engineered for particular tasks and provide superior access and protection
• Handle length - Longer handles provide greater leverage for stubborn fasteners, whilst shorter spanners suit tighter working spaces

Frequently Asked Questions

What's the difference between a box spanner and a ring spanner?

A box spanner is a tubular tool that fits completely over a nut or bolt head, often used with a tommy bar for leverage. A ring spanner has a closed loop at one or both ends and is generally shorter. Box spanners excel in deep or recessed applications where standard spanners cannot reach.

How do I prevent damaging nuts and bolts when using spanners?

Always use the correct size spanner that fits snugly without play. Pull rather than push where possible for better control, and apply penetrating oil to seized fasteners before attempting removal. Replace worn spanners that no longer grip properly.

Can I use the same spanners for metric and imperial fasteners?

No, metric and imperial sizes are different and require their respective spanners. Using the wrong type will result in poor fit, rounded fasteners, and potential injury. Always check your fastener type before selecting your spanner.
