Rated 4 out of 5 by Surprised!! Have never used masonry bolts before,always been a 'plug and screw' man!! Read reviews so thought I'd give them a go,and now converted! Used to secure two gate posts inside a brick archway,was able to screw in with ease and loosen and retighten to allow packers to be inserted. Definitely will be using again. 1 Feb 2016
Rated 5 out of 5 by dewalt fixings I used these to hold 100mm x 50mm timber to steel as a self tapper worked great 26 Dec 2015
Rated 5 out of 5 by Amazing Product Used these bolts to fix No. 8 2x1 box steel posts to a concrete garage base to secure a walkway around it. Used same sized masonry bit and ratchet spanner. Bolt cut into the hole as smooth as anything. Made a mistake with one, simply undid the bolt to correct and re-tightened - no problem at all. Materials drilled were concrete base and good quality blocks. Would highly recommend. 14 Dec 2015
Rated 5 out of 5 by Just the job The plastic garden shed that I secured to the base with these bolts has already withstood Abigail and Barnie, so clearly fit for purpose 21 Nov 2015
