It’s worth mentioning that there’s another type of soft-metal shield, called the lag shield anchor. Soft-metal shields are suitable for fastening to concrete, block, and brick. 6-8 shields you must purchase the sheet metal screws separately. Expect to pay about $15 for a box of 100 No. Soft-metal shields are commonly available in lengths ranging from 3/4 to 1 1/2 inches, and in three different diameters for accepting screw sizes from No. Also, you must clean all the dust out of the hole prior to hammering in the shield. If it’s too small, the shield will crush when you tap it in. If the hole is too large, then the shield will spin in the hole. When installing a soft-metal shield, it’s important to drill the proper-size hole. The shield is made from soft, almost lead-like material that accepts a sheet-metal screw. It’s little more than a ribbed, slightly tapered hollow metal sleeve that fits into a hole. The soft-metal shield is one of the oldest and most effective concrete fasteners available. That’s because concrete fasteners grip much more securely in clean, dust-free holes. It’s also important to always blow or vacuum out the concrete dust from the hole before inserting the fastener. If you don’t own a hammer drill you can use a standard corded electric drill or cordless battery-powered drill, but it’ll take at least twice as long to drill each hole. The quickest, easiest way to drill into concrete is with a hammer drill, which uses both bit rotation and concussive blows to bore the holes. Note that before installing most concrete fasteners, you must first drill a hole with a carbide-tipped masonry bit. Here, we’ll explain four different techniques and types of concrete screws and fasteners specifically designed for attaching to concrete, and most can also be used to fasten into brick, stone, and concrete block as well.

Unfortunately for many DIYers, using concrete screws or fasterners can be a frustratingly difficult and almost impossible task. To concrete surfaces, or securing steel post anchors to a concrete patio. There are many home-improvement projects that require you to screw or nail into concrete, such as when affixing shelf brackets to a concrete basement wall, screwing down a 2x4 sole plate to a concrete floor, fastening metal conduit
