Popular Rawlplug Bolts

The Through Bolt range represents Rawlplug's most versatile mechanical anchor solution, featuring expansion sleeves that grip concrete, brick, and stone as the bolt is tightened. Available in various diameters and lengths, through bolts suit everything from lightweight bracket fixing to heavy structural connections, with options for masonry, solid concrete, and hollow substrate applications.

Hex Head Bolts provide the traditional choice for structural connections and machinery mounting, offering high torque capacity and compatibility with standard spanners and socket sets. The range includes both fully threaded and partially threaded variants, allowing precise engagement length specification for different fixing scenarios.

Coach Bolts (also known as cup square bolts) feature a domed head and square neck section that prevents rotation during nut tightening, making them ideal for timber-to-masonry connections, fence post mounting, and applications where the square shoulder provides additional anti-rotation security.

For specialist applications, Tooled-Up stocks Stainless Steel Bolts from Rawlplug's marine and chemical-resistant range, providing superior corrosion protection in aggressive environments including swimming pools, coastal installations, food processing facilities, and pharmaceutical manufacturing plants.

Safety and Compliance

All Rawlplug Bolts supplied through Tooled-Up meet relevant British Standards and European Technical Approvals (ETA), ensuring compliance with Building Regulations and structural engineering requirements. Products are manufactured under ISO 9001 quality management systems, providing traceability and consistency that Building Control officers and structural warranty providers require.

Correct installation practices are essential for achieving certified load capacities. Always follow Rawlplug's published installation guidelines regarding hole diameter, drilling depth, substrate condition, and tightening torque. Ensure substrates are structurally sound, free from contamination, and of sufficient thickness to develop the full embedment depth required for the specified load rating.

When working at height or installing safety-critical fixings, always conduct appropriate risk assessments in accordance with HSE guidance. Use calibrated torque tools for applications where precise tightening specifications are provided, and maintain records of installation parameters for warranty and compliance documentation. For structural applications, engage qualified engineers to verify fixing specifications and load calculations before commencing installation work.

Frequently Asked Questions

What's the difference between through bolts and expansion anchors in the Rawlplug range?

Through bolts feature a threaded bolt that passes completely through the fixing and expansion sleeve, with tightening the nut causing the sleeve to expand against the substrate. This provides removable fixings with high load capacity. Expansion anchors typically feature a shield or sleeve that expands as the bolt is tightened, but the bolt doesn't necessarily pass through the entire assembly. Both are available in the Rawlplug range for different application requirements.

Can Rawlplug Bolts be used in cracked concrete?

Standard through bolts and mechanical anchors from Rawlplug are designed for use in non-cracked concrete only. For applications where cracking may occur due to seismic activity, dynamic loading, or edge distances, Rawlplug offers specialist anchor systems with European Technical Approval for cracked concrete. Always check the product's technical datasheet and ETA documentation to confirm suitability for your specific substrate condition.

How do I calculate the correct embedment depth for Rawlplug Bolts?

Embedment depth requirements are specified in Rawlplug's technical documentation for each product and are based on the bolt diameter, substrate material, and required load capacity. As a general guide, minimum embedment in concrete is typically 8-10 times the bolt diameter for full load capacity, but always consult the specific product's installation instructions. Ensure drill holes are cleaned of dust and debris before installation to achieve proper embedment.

Are Rawlplug Bolts suitable for outdoor applications?

The suitability of Rawlplug Bolts for exterior use depends on the material grade and surface treatment. Standard zinc-plated bolts provide adequate corrosion protection for internal and sheltered external applications. For exposed outdoor use, particularly in coastal or industrial environments, specify hot-dip galvanised or stainless steel options from the Rawlplug range, which offer enhanced corrosion resistance for long-term durability in aggressive conditions.

What torque settings should I use when installing Rawlplug Bolts?

Tightening torque specifications vary depending on bolt diameter, material grade, and substrate type. Rawlplug provides detailed torque values in their technical literature for each product range. Over-tightening can damage the substrate or cause anchor failure, whilst under-tightening prevents proper expansion and reduces load capacity. For critical applications, always use a calibrated torque wrench set to the manufacturer's specified values to ensure optimal performance and compliance with structural requirements.
