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!

Worked great

Be careful! Very nice stainless steel product but the metric size may be a bit of a challenge considering most drill bits are SAE. Hopefully I had a unique situation in my masonry but had to do a little customizing

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

I installed these a couple years ago along with steel cable and wire rope clamps for hanging 48' heavy duty string lights from my patio to 6' block wall. Although I take the lights down in October, they've held up fine through a few of our SoCal Santa Ana's whipping the lights around. These anchors have not budged, tarnished or let me down in any way. Would do it again.

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.

Arrived quickly, just as described.

The sleeve would not anchor on to wall and kept spinning.
