Heavy duty L-shaped screw hooks supplied as a complete, load-matched pair with their own expansion wall plug - no separate plug-buying or size-guessing needed. Steel hook with a zinc plated finish for corrosion resistance, suited to both indoor and outdoor fixing points. Split expansion wall plug design - as the hook is screwed in, its shank forces the plug's split sides outward against the drilled hole for a secure grip. Designed specifically for solid masonry fixings into brick, block or concrete. Four matched size pairs from a light-duty 6x30mm up to a heavy-duty 12x60mm for larger loads.
