Rawl R-WHO Concrete Frame Screws

This variant of the Rawl R-WHO Concrete Frame Screw is supplied in a 52mm length with a 7.5mm diameter, offered in a pack of 100. As the shortest length in the R-WHO range, the 52mm variant is ideal for applications requiring a compact fixing — particularly useful for thinner frame profiles or where substrate depth is limited but a secure, reliable fixing is still essential.

Installing directly into concrete, solid brick, and masonry without the need for plugs or anchors, the R-WHO keeps the installation process simple and efficient. The expansion-free fixing action minimises stress on the substrate, and the flat countersunk head sits flush for a tidy finish. Screws are removable for temporary works, adding further versatility to this compact option.

Features and Benefits:
• No plugs or anchors required — simplifies installation and saves time
• Expansion-free fixing imposes less stress on the substrate
• High load resistances from a relatively small hole diameter
• Flat head for flush installation with window and door frames
• Easily removed for temporary works
