3/8x4" 10Pcs Inch Standard Fasteners for Heavy-Duty Zinc Wedge Anchors for Cement and Concrete

These are very strong.

Using these bolt's to frame interior walls on an outbuildings slab-on-grade is a piece of cake. Used the entire box without one failure.

These anchors are easy to install and hold very well. I used them (4each) to fasten flanges to concrete for dock wall safety rails.

Buen artículo.

Stronger than other 5/16 anchors I have used. Good product. Holds tightly.

Drilled pilot holes with 3/8" concrete drill. Drove anchors in with a few strokes of a small sledge hammer (with nut threaded ALMOST, but not to the top of the anchor). No bending. Tightened up securely. Highly recommend!

Good value. Worked perfectly. Fit in a 1/2” hole and snugged up nicely.

Nice working product
