About Pin Spanners
Pin spanners are specialised tools designed primarily for tightening and loosening lock nuts on angle grinders and other power tools. Featuring two protruding pins that engage with corresponding holes in the lock nut, these essential workshop tools provide the precise grip needed to securely fasten or remove grinding discs, cutting wheels, and sanding accessories. MyToolShed.co.uk stocks a comprehensive range of pin spanners from trusted brands including Bosch Professional, Makita, Flexipad, Sealey, and Faithfull.
Available in both fixed and adjustable designs, pin spanners come in various sizes to accommodate different lock nut diameters. Fixed-size models are colour-coded for quick identification, whilst adjustable versions offer versatility across multiple tools and applications. Whether you're a professional tradesperson maintaining a fleet of power tools or a DIY enthusiast working on home projects, having the correct pin spanner ensures safe disc changes and prevents damage to your equipment.
Applications
- Tradespeople: Construction workers, metalworkers, fabricators, and maintenance engineers who regularly use angle grinders for cutting and grinding tasks
- Workshop environments: Industrial facilities, engineering workshops, and manufacturing plants requiring frequent disc changes on grinding equipment
- Automotive trades: Mechanics and bodywork specialists using angle grinders for metal preparation and finishing
- DIY enthusiasts: Home workshop users maintaining their own power tools and changing grinding accessories
- Joinery applications: Specialist tools like the Makita biscuit jointer pin spanner for woodworking professionals
Choosing The Right Pin Spanners
When selecting pin spanners from MyToolShed.co.uk, consider the following factors to ensure compatibility and convenience:
- Tool compatibility: Match the spanner to your specific grinder model - manufacturer-specific options from Bosch, Makita, and other brands guarantee perfect fitment
- Pin spacing: Measure the distance between holes on your lock nut, typically ranging from 20mm to 35mm for standard angle grinders
- Fixed versus adjustable: Adjustable spanners offer flexibility across multiple tools, whilst fixed-size models provide a more compact solution for dedicated equipment
- Build quality: Hardened steel construction ensures durability and prevents pin damage during high-torque applications
- Colour coding: Fixed-size spanners with colour-coded handles (like the Flexipad range) enable quick size identification in busy workshops
Frequently Asked Questions
Can I use any pin spanner on my angle grinder?
Whilst adjustable pin spanners offer versatility, it's essential to match the pin spacing to your specific lock nut. Manufacturer-specific spanners are engineered for precise fitment and optimal performance with their corresponding power tools.
Why won't my angle grinder lock nut loosen?
Ensure you're turning the lock nut in the correct direction (typically opposite to the disc rotation). The spindle lock button must be fully engaged before applying force. If the nut remains seized, apply penetrating oil and allow time for it to work before attempting again.
What's the advantage of adjustable pin spanners?
Adjustable pin spanners eliminate the need for multiple fixed-size tools, making them ideal for workshops with various grinder models. They're particularly cost-effective for tradespeople who work with different brands and sizes of power tools.
