They exert a ton of outward pressure, which could literally “wedge” the concrete apart. Drill one hole and install that fastener first. You may want to waterproof the walls first, and if so, your local building codes may require you to seal all the seams. The lead thread will dull and hit a point where it will no longer be able to cut threads and will stop screw penetration.

Standard wire tie configurations have been tested for their capacities. This is due to minor variances over the length of the walls. The pre-drilled hole must be a minimum of 1/2-in.

Thread styles can greatly differ, especially in depth and spacing. Buy a variety of lengths so you have the correct screw size on hand. In hard, dense materials like concrete or stone, this minimum 1-in. You may have to experiment with a few different lengths to find a screw that you can drive fully and that holds securely.

Cintec anchor system consists of a stainless-steel anchor body encapsulated in a fabric sock. You’ll develop a feel for the right amount of speed after driving a few screws. You also need carbide-tipped concrete bits and a nut driver (hex driver). First, drill the proper size pilot hole (3/8-in., 1/2-in., etc.) through the wood or metal and into the concrete. Use a special bit in your hammer drill to drill a pilot hole through the workpiece (if it’s wood) and right into the concrete.
Hex heads are easier to drive but the heads will protrude slightly above the surface after tightening. Not good for crumbly concrete or mortar. Try to get the anchor into the solid portion of the concrete block for added security and strength. Overtightening can cause them to break free. Drill a hole the size of the anchor through the wood and into the concrete. Be sure the washer is in place and tighten the nut with a wrench.
