Frequently Asked Questions

What base materials are suitable for Rawlplug through bolts?

Rawlplug through bolts are designed for use in solid base materials including concrete (minimum C20/25), natural stone, solid brick, and dense concrete blocks. They're not suitable for hollow materials or lightweight blocks. Always ensure the base material meets minimum depth and strength requirements specified in the technical documentation.

How do I select the correct through bolt size?

Selection depends on the load requirements, base material characteristics, and fixture thickness. Consider the fixture's working load, safety factors, and embedment depth. Rawlplug provides detailed load tables and technical specifications to assist with proper sizing. When in doubt, consult the manufacturer's technical support team.

Can Rawlplug through bolts be used outdoors?

Yes, when you select the appropriate corrosion protection grade. Galvanised versions suit most outdoor applications, whilst A4 stainless steel through bolts offer superior resistance in coastal or chemically aggressive environments. Always match the corrosion protection to the installation environment's exposure class.
