Simpson Strong-Tie STB2-50700 Strong-Bolt 2 — 1/2-in. x 7-in. Wedge Anchor (25-Qty)

This product works great if you follow the directions. You must use a blow gun to clear the dust from the hole, if you do it will work perfectly. I've been using these for 30 + years, with very little trouble, usually my fault.

I used these anchors to install a railing on my concrete porch. The definitely meet my expectations. So easy to use and the quality is great. I would definitely recommend this product to any diyer or professional.

Good quality.

Easy to use and works very well. Couldn't pull the equipment out of the ground with a pallet jack so that's good although when hit with a truck it will most likely fail.

This particular type of fastener, not this brand in particular, is the least reliable type of hardware I've ever used. Only about 75% of these will actually drive into your drilled holes correctly and will be secure. They bend easily when driving into the pilot holes and will frequently spin in place when attempting to tighten the hex nut. If you need to secure something to concrete, use these as a last resort.

6 of these bolt, 3 for each rack is holding up my lumber storage rack. I have tested it. I weight almost 200Lbs, and it can hold my weigh at a 45 degree pull. Super happy with the performance.

Worked as expected

Used these anchors to attach sill plate to a concrete slab. Best quality and price from Amazon.

Bought damaged package and only 16 anchors were in the box out of 25 ! Strongly disappointed

Missing all nuts and quantity at time when received
