CONFAST 3/8" x 3-3/4" Wedge Anchor Zinc Plated (Box of 50)

Great product and price

I use these as anchors with which to move granite boulders. I've had good luck with 3/8, 1/2 inch moving boulders up to 3T. Mostly dragging but in some cases moving up an incline. Tend to be a bit weak in shear, so insure that you tighten any lifting eye or bracket firmly. Torque specs are 30 ft lb for the 3/8 and 60 ft lb for 1/2 inch; I can't see how you could overtighten them.Do not allow persons or body parts to remain under the load when lifting hazardous items.

They worked great

Good value, also

These are great anchors for wall bottom plates. I haven't cast wall anchors for years. I prefer these anchors over cast in place anchors because I don't have to try to figure out where my studs and plate splices are going to be when I'm pouring concrete. I can place them in the best position after the walls are in place. I generally drill a 1/2" hole through the wood and a 3/8" concrete drill into the concrete. The anchors have a reduced diameter extension on the end to prevent damaging the threads while setting. I slip on the washer and thread the nut just past the start of the thread then drive the anchor down hard with a hammer; then just a few turns to tighten the nut and the job is done. There is a significant savings in buying the box of 50 over the by-the-piece price at the hardware store.

I've had red-head anchors pull out when tightening just because they never bit into the concrete enough to engage the collar, these have a stamped tab that hasn't failed me yet. I do wish Confast had more thorough performance documentation though.

Great product and easy to use
