Concrete Anchors Anchor Stud are designed for welding to flat surfaces or welding in the fillet or to the heel of angles. Length is before weld. Stud diameters (D) 1/2 and below will be approximately 1/8 shorter after welding. 5/8 will be approximately 3/16 shorter after welding.
How to use: First, drill the proper size pilot hole (3/8-in., 1/2-in., etc.) through the wood or metal and into the concrete. Slip the sleeve anchor into the hole. Hold the object you're fastening firmly against the wall because the anchor will draw it only slightly tighter as you tighten the screw or nut.he best way to drill a hole into concrete, concrete block, mortar and brick is to use a hammer drill. A standard drill will do OK in soft brick and mortar, but it'll just frustrate you and burn out bits in harder materials. DON'T BURN OUT YOUR FAVORITE 3/8-IN. DRILL.
