FAQs

What size hole do I drill for M20 studs?

Drill a 24mm hole to a depth of 170mm, then clean it thoroughly with a blow-out pump and brush before injecting resin.

Which resin should I use?

Polyester resin suits general-purpose fixing into masonry; vinylester resin gives higher performance in concrete and damp holes. Check the cartridge for curing times.

Zinc or galvanised?

Zinc-plated studs are for dry, internal environments. Hot dip galvanised studs have a corrosion rating of 4 and are the choice for external work.

Can I use them in hollow block?

Yes – use a resin sleeve in the hole so the resin is contained and keys around the cavities.
