Scaffold ring or eye bolts commonly have an M12 thread with an eye sized to pass a 48.3 mm scaffold tube, screwing into an anchor tube or nylon dowel set in a pre-drilled hole. Match the drill diameter and dowel length to the anchor so it seats fully in solid masonry.

Scaffold eye bolts and ring anchors are typically forged or zinc-plated steel, with galvanised finishes for repeated outdoor use and corrosion resistance. The nylon dowels or wall plugs are UV-stabilised nylon, giving a durable, reusable anchoring point in brick, block or concrete.

To install a scaffold wall tie, drill the specified hole in solid masonry, insert the nylon dowel or anchor tube, then screw in the eye bolt until tight and flush. Pass the tie tube through the eye and couple it to the scaffold, checking each anchor is set in sound brick or block, not a mortar joint.

A scaffold ring anchor's safe working load depends on the masonry, dowel and bolt size, so pull-out capacity is tested on site rather than assumed from a single figure. GeZu Impex lists the thread size and dowel dimensions for each holder so you can specify the correct drill and anchor for the substrate.
