Zinc?plated steel construction, robust and corrosion resistant. Push through the fixture, insert into pre-drilled hole, then tighten – the cone activates expansion. Prevents over-tightening and ensures consistent load performance. As you tighten the screw or hex nut, the internal cone pulls the sleeve outward, clamps it firmly to the substrate walls. Ideal for load-bearing applications. Requires a dust-free hole for reliable performance ensure debris is cleaned before installation.
