Sleeve Anchors

About Sleeve Anchors

Sleeve anchors are heavy-duty fixings designed to create secure fastenings in solid masonry materials including concrete, brick, stone and blockwork. These versatile anchors consist of a threaded bolt or stud surrounded by a metal sleeve that expands when tightened, creating a reliable mechanical grip within the base material. MyToolShed.co.uk stocks a comprehensive range of sleeve anchors from trusted manufacturers including Rawlplug and Forgefix, offering various configurations such as loose bolt, projecting bolt, eye bolt and hook bolt designs to suit different installation requirements.

Available in multiple sizes and finishes, sleeve anchors provide exceptional load-bearing capacity and are ideal for permanent fixings where strength and durability are essential. The expansion mechanism ensures consistent performance across different densities of masonry, making them a dependable choice for both professional tradespeople and demanding DIY applications.

Applications

Sleeve anchors are widely used across numerous trades and industries, including:

• Builders and general contractors – securing structural steelwork, fixing door frames, and installing heavy equipment to masonry walls
• Electrical contractors – mounting cable trays, distribution boards, and conduit support systems
• Plumbers and heating engineers – fixing boilers, radiators, and pipework brackets to solid walls
• Shopfitters and joiners – installing racking systems, shelving units, and commercial fixtures
• Fencing and gate installers – anchoring posts and hinges to concrete bases
• HVAC engineers – mounting air conditioning units and ventilation equipment
• Facilities maintenance – general heavy-duty fixing applications in commercial and industrial settings

Choosing The Right Sleeve Anchors

When selecting sleeve anchors from MyToolShed.co.uk, consider these important factors:

• Base material: Ensure the anchor is suitable for your substrate – concrete, brick, or stone – and verify the material density and condition
• Load requirements: Calculate the expected static and dynamic loads to determine the appropriate anchor size and quantity needed
• Bolt configuration: Choose between loose bolt (removable fixture), projecting bolt (fixed installation), or specialist designs like eye bolts and hook bolts depending on your application
• Length and diameter: Select anchors with sufficient embedment depth for your base material thickness and required load capacity
• Environmental conditions: For outdoor or corrosive environments, opt for galvanised or stainless steel finishes to prevent rust and degradation
• Installation access: Consider whether through-fixing or pre-positioned installation is required based on your site conditions

Frequently Asked Questions

What's the difference between loose bolt and projecting bolt sleeve anchors?

Loose bolt anchors feature a removable bolt that can be unscrewed after installation, allowing you to detach and reattach fixtures as needed. Projecting bolt anchors have a permanently fixed bolt that protrudes from the wall, ideal for permanent installations where removal isn't required.

Can sleeve anchors be used in hollow blockwork?

Sleeve anchors are designed for solid masonry materials and require a solid substrate to function correctly. For hollow blocks or cavity walls, consider specialist hollow wall fixings instead, which are also available from MyToolShed.co.uk.

How do I determine the correct embedment depth?

The embedment depth should typically be at least 4-5 times the anchor diameter for concrete applications. Always refer to the manufacturer's technical specifications and load tables provided with your chosen anchor to ensure adequate performance and safety margins for your specific application.
