Review on Red Head LDT 3850 Diameter Tapcon by Ryan Turner

These fasteners worked great. Fastening the PT base plate to the concrete floor. Pre-drill the slab into the concrete floor using a hammer drill and a 5/16-inch masonry bit. You will need a 9/16" impact wrench to install the anchor. Make sure you drill a hole longer than the screw or you will be screwed. These are top quality fasteners and indeed arrived early. Thanks very much!
