Yasorn 5-Pack Stainless Steel External Hex Expansion Bolt M8x60mm

I have used different types of anchors over the years for different jobs, but this was the first time I used the concrete expansion bolts. After viewing a couple of YouTube demonstrations of how to install them I had no trouble using them to secure my swimming pool handrail. It is solid! These are excellent anchors!

The anchors were solidly made and were purchasedto replace flimsy anchors which came in a package with handrails. I installed these into concrete to support the handrail. I am very pleased with these anchors. Thanks

When you get it right, they work well. I struggled and had to pull some out for a re-do.

Good quality

The 8MM anchor requires a 12mm hole in concrete to be secure. This is slightly larger than 7/16. Not having a 12MM percussion bit I used a 7/16 bit to drill into the concrete and "wobbled" it a bit as I was drilling down to create a slightly oversize hole. You have to be careful though as too much "wobble" will result in a slightly oversize hole which means grip strength will be reduced. If you need stainless and need to be able to take down what you have secured and not have a stud sticking up to trip on this will work well. Suggest you buy a metric percussion bit and use a hammer drill.

The M6 sized option requires a 9mm predrilled hole. This is not a typical size you're gonna find in most DIY drill bit sets and typically going to need to specifically purchase this unless you have a higher end/larger set of bits. There's no real equal in terms of american conversion either.A 3/8" or a 10mm drill bit will work though the sizing is slightly too large. It is not so large that it wont work, but the bolt is smaller enough in diameter that when you try to tighten the nut to expand the sleeve it just spins the whole thing so you just need to put a little stuffing inside like a piece of cloth that'll keep the sleeve snug enough so that it doesnt spin when you tighten the nut and a few turns will expand the sleeve enough that it tightens against the perimeter of the whole and secures itself.First impressions are it holds real tight still. My application doesn't require a lot of strength but I'd imagine you would not want to test these to their max of around 90lbs without use of a proper 9mm drilled hole to secure these in. They probably lose some of that strength in a 3/8 or 10mm hole that is slightly too large.

Works great

Arrived quickly, just as described.

C'est parfait!! Le descriptif représente tout à fait la pièce commandée.

Sehr gute Qualität. Top Preis

Perfekt, 1a Qualität, die Anker halten bombenfest - gerne wieder

Emballage : Enveloppe cartonnée.Crochet à suspension acheté pour y suspendre un écran de projection de 6kg. Le poids de traction est supérieur lorsqu'on déroule l'écran vers le bas. Dans un plafond en béton ça tient très bien, très solide.Pour fixer le crochet M6, j'ai dû utiliser un foret de 10mm car le bout qui rentre dans le plafond est un peu plus évasé. Au vissage, cela écart l'enveloppe extérieure pour se fixer dans le béton.Le vissage est compliqué surtout quand c'est au plafond car il faut visser l'écrou d'une main en tenant le crochet de l'autre pour qu'il reste dans la bonne position, tout ça les bras au-dessus de la tête. Mais une fois bien vissé ça tient bien.Pour : Solide.Contre : Méthode de vissage compliqué seul.Recommandé : Oui.

Da im Außenbereich verwendet sollten sie komplett aus Edelstahl sein. Obwohl nicht gerade billig, erfüllten sie ihren Zweck perfekt.Die Qualität ist sehr gut und Korrosionsprobleme wird es damit nicht geben.
