About Open Ended Spanners
Open ended spanners are essential hand tools featuring U-shaped jaws at one or both ends, designed to grip and turn nuts and bolts from the side. Available in metric, imperial, and specialist sizes, these versatile tools are fundamental to any professional toolkit or home workshop. MyToolShed.co.uk stocks an extensive range of open ended spanners from trusted brands including Facom, Elora, Draper, and Bosch Professional, suitable for everything from automotive maintenance to engineering applications.
The collection includes single and double ended spanners, VDE insulated models for electrical work, midget spanners for confined spaces, and long-reach variants for accessing recessed fixings. Whether you need a comprehensive spanner set or individual sizes for specific tasks, MyToolShed offers quality tools manufactured to exacting standards for reliable performance and longevity.
Applications
Open ended spanners are indispensable across numerous trades and applications:
- Automotive mechanics - servicing engines, suspension systems, and general vehicle maintenance
- Plumbers and heating engineers - working with pipe fittings, radiators, and boiler installations
- Electricians - using VDE insulated spanners when working near live 240v electrical systems
- Plant maintenance and engineering - machinery assembly, repair, and routine maintenance
- Construction tradespeople - general site work including scaffolding and structural assembly
- Bicycle mechanics - specialist pedal spanners and general cycle maintenance
- DIY enthusiasts - home repairs, furniture assembly, and general maintenance tasks
Choosing The Right Open Ended Spanners
Consider these key factors when selecting open ended spanners:
Measurement system: Determine whether you need metric (mm), imperial (AF/inches), or BA sizes based on your typical applications. Many professionals maintain both metric and imperial sets for versatility.
Single or double ended: Double ended spanners offer two adjacent sizes in one tool, reducing the number of spanners needed. Single ended models typically feature longer handles for increased leverage.
Special requirements: VDE insulated spanners are essential for electrical work near live 240v circuits. Midget spanners suit confined spaces, whilst long-reach versions access recessed fixings. Offset designs provide clearance over obstructions.
Quality and material: Chrome vanadium steel offers excellent strength and durability. Professional-grade spanners from brands available at MyToolShed.co.uk feature precision-machined jaws that minimise wear and prevent rounding of fasteners.
Sets versus individual spanners: Complete sets provide comprehensive coverage and better value, whilst individual spanners allow you to replace worn tools or add specific sizes to your existing collection.
Frequently Asked Questions
What's the difference between open ended and ring spanners?
Open ended spanners have U-shaped jaws that slide onto fasteners from the side, allowing use where access is restricted or continuous rotation isn't possible. Ring spanners have closed circular ends that completely surround the fastener, providing better grip and reduced risk of slipping, but require overhead access.
Are VDE insulated spanners necessary for electrical work?
Yes, when working on or near live electrical equipment up to 1000V AC (including 240v mains installations), VDE insulated spanners provide crucial protection against electric shock. They meet strict safety standards and are essential for professional electricians.
How do I prevent rounding bolt heads with open ended spanners?
Ensure the spanner fits snugly with minimal play, position it fully onto the flats of the fastener, and pull rather than push where possible. Quality spanners with precision-manufactured jaws significantly reduce the risk of damaging fasteners.
