Security Chains

About Security Chains

Security chains provide robust physical protection for valuable tools, equipment, machinery, and property. Available in various link diameters from 6mm to 12mm, these hardened steel chains offer flexible yet formidable security solutions that can be wrapped around irregular shapes and anchored to fixed points. MyToolShed.co.uk stocks professional-grade security chains from trusted manufacturers including Abus, Squire, Masterlock, and Blue Spot, suitable for both commercial and domestic applications.

Unlike cables or standard chains, security chains are manufactured from hardened or boron-alloy steel with through-hardening processes that resist cutting, sawing, and bolt cropping attempts. Round section chains offer flexibility and are difficult to grip with cutting tools, whilst square link chains provide maximum strength and resistance to twisting. When combined with a high-security padlock, these chains create a comprehensive security system for construction sites, workshops, storage facilities, and residential properties.

Applications

• Construction Sites: Securing ladders, generators, compressors, and plant equipment overnight or between shifts
• Trade Vehicles: Protecting tools and equipment stored in vans, trucks, and trailers
• Workshops and Garages: Safeguarding expensive power tools, machinery, and workshop equipment
• Agricultural Use: Securing gates, farm machinery, quad bikes, and trailers
• Groundswork and Landscaping: Protecting diggers, mini-excavators, and material stockpiles on site
• Property Security: Securing gates, sheds, storage containers, and outdoor equipment
• Industrial Facilities: Protecting machinery, materials, and access points in warehouses and factories

Choosing The Right Security Chains

Link diameter is the primary factor determining security level—6mm chains suit lighter applications and temporary security, whilst 10mm and 12mm chains offer maximum protection for high-value equipment. Consider the chain length required to wrap around your items and anchor points, allowing sufficient slack for the padlock. MyToolShed.co.uk offers chains in various lengths to suit different securing requirements.

Material quality matters significantly: hardened steel chains resist cutting tools better than standard steel, whilst boron-alloy steel provides exceptional strength-to-weight ratios. Square link chains generally offer superior security compared to round links but with reduced flexibility. Look for chains rated to recognised security standards, and always pair your security chain with a quality padlock of equivalent security rating—a chain is only as strong as its weakest component.

Consider portability needs for mobile tradespeople versus permanent installations. Loop chains with welded end links simplify securing to anchor points, whilst standard lengths offer maximum versatility. Weather resistance is essential for outdoor use—look for chains with protective sleeves or corrosion-resistant finishes to maintain security performance over time.

Frequently Asked Questions

What link diameter do I need for tool security?

For general tool and equipment security, 8mm to 10mm link diameter chains provide excellent protection against opportunistic theft. Construction sites and high-value machinery benefit from 10mm or 12mm chains which resist bolt croppers and power tools more effectively.

Can security chains be cut?

Whilst no chain is completely impenetrable, hardened security chains from brands like Abus and Squire available at MyToolShed.co.uk are designed to resist common attack methods including bolt croppers, hacksaws, and angle grinders, significantly delaying or preventing theft attempts.

What length security chain should I buy?

Measure the circumference of what you're securing plus the distance to your anchor point, then add 150-200mm for the padlock. It's better to have slight excess length than a chain that's too short to properly secure your equipment.
