Red Head TruBolt® 1/2 x 5-1/2 Inch Wedge Heavy-Duty Concrete Anchors, 10 PCS, Versatile Threaded Design for Fastening into Solid Concrete with 360-Degree Contact, Stainless Steel

They worked as expected, and are holding well.

I combined this with a stronghold 6x6 brace for anchoring cedar posts. As long as as you have a concrete slab slightly thicker then the length of anchor bolt they have tremendous hold.

These are going to work great, BUT 5 of the wedge anchors missing, all 10 nuts and washers were in the box. No big deal because I only needed 6, so I have 1 extra from another job. Great price too.

Very hefty construction, and great resale packaging.

I liked everything about this product except that several of the anchor bolts pulled through and out of the concrete when I tightened them down. I wish they had a better expansion mechanism integrated into them.

Anchring a power hammer. Time will tell.
