Amtech S5910 10 Piece M6 x 50mm Expansion Bolts

I had to attach a few study hooks to the inside of my red brick garage and quickly realised the hardware supplied with the hooks was insufficient to hold the weight of anything other than a sheet of paper so bought these in the hope that they'd so a better job.I have to say I was worried about the quality given some of the reviews but I had nothing to worry about, all 4 I used fitted first time with no problem and anchor the hooks to wall so well I could hang off them. Brilliant job!It wasn't clear what size drill bit that was required so if anyone is struggling I used a 12mm one having made an initial pilot hole about 4mm first. Some were more of a snug fit than others so required a gentle tap with a hammer but that could well have been my DIY abilities or my drill. Either way once full tightened they were rock solid.These absolutely exceeded my expectations.

Good value for money, however their construction is not as sturdy as that of Rawlbolts.

Very pleased with this item .would definitely buy again.

Used these before and found them easy to use.

Managed to salvage 4 bolts out of 10 so I could finish my job, but would avoid these when buying again
