Hollow Wall Cavity Anchor Kit – 500 NR M5 x 45 + Applicator Gun

This hollow wall cavity anchor kit gives you 500 M5 x 45mm medium anchors and a dedicated applicator gun in one purchase. If you’re regularly fixing into plasterboard or cavity walls, having the right tool for the job makes a genuine difference. These aren’t the plastic toggles you fish around behind the board hoping for the best — they’re all-metal anchors designed to pull up tight and stay there.

The anchors feature anti-rotation teeth that bite into the base skin of the board as the fixing is set. That matters more than it sounds. Without it, the anchor can spin in the hole when you’re driving the screw, leaving you with a fixing that feels solid until it isn’t. The teeth prevent that from happening, giving you consistent anchorage every time.

All-metal construction also means these are suitable for applications where heat resistance is a consideration. Not something you need on every job, but worth knowing when you’re working near electrical enclosures, boiler rooms, or any installation where elevated temperatures are possible.

Where This Hollow Wall Cavity Anchor Kit Earns Its Keep

The applicator gun is the part that changes the pace of the job. Hand-setting cavity anchors one at a time is fine if you’ve got a dozen to do. When you’re looking at a run of 50 or more fixings across a partition wall, a stud wall, or a ceiling board installation, that repetitive motion adds up quickly. The gun is built for exactly that kind of sustained use — load, position, squeeze, done. Move on.

Five hundred anchors is a serious quantity, and this kit is priced accordingly. It suits contractors taking on fit-out work, partition installers, and anyone running multiple jobs where plasterboard fixing is a routine part of the day rather than an occasional task.

M5 x 45mm is a medium-duty specification — enough for shelving brackets, cable management, switch plates, mirror fixings, and similar loads. Not the right choice for structural brackets or anything safety-critical on plasterboard, but for the bulk of everyday secondary fixing work, this hollow wall cavity anchor kit covers the ground well.
