M4 Drop in Anchors Brass Wall Anchor Expansion Bolt Sleeve Fischer Brass Plug for Anchoring into Concrete Masonry Bricks, Natural Hard Stones (Pack of 10)

Excellent

I needed a strong wall anchor that I could easily remove later on, for a really damp location. That's a difficult combination, as it rules out steel (which rusts) and plastic (not strong enough). I used the same type of thing decades ago and was surprised to find someone still making them.They are beautifully machined and very accurately made. I used these with stainless bolts and they are excellent. Well able to take the weight of a bench seat and a barbecue table on a stone wall. With care, they are also able to be removed if needed.Very happy with these, as I'm sure you would be.

Forget anchor bolts. I’ve tried and tried and they are so difficult to set and get them fitted properly….these fixings however are just a dream. 12mm hole, lightly screw the bolt in and gently drive it in with a few taps of a hammer and that’s it. The fixing is so tight. We’ve started using these with security headed bolts and they are incredibly strong. Just purchased some more

I used these anchors to fix security pillar lights to a paved patio. The lights come with screw on nuts designed to fit M8 threaded studs. These anchors worked a treat I drilled a 10mm hole popped them in and screwed the studs in, worked first time. Much easier to use that expanding hilti type bolts.

Being brass they are far too soft and just don’t bite in to concrete.I drilled a concrete garage floor and tried to use them to anchor down a motorcycle choc, but as the bolts were tightened, they just started to pull out of their holes.Used traditional steel anchors, and they were fine.

Great productTight fit in 10mm hole but solid fixing for 10 mm eye bolts

All the fixing didn’t have the eyes need to splice the fixing making them useless
