To install either kind of hammer anchor, set the product in position and then drill the masonry behind it. Make sure to use the size drill bit specified by the producer. The hole can be any depth as long as it is deeper than the length of the anchor. Insert the anchor through the product and into the hole, and drive it down tight with a hammer.
Concrete Screws Concrete screws came onto the marketplace in the mid-1970s and have become a staple of lightweight applications. They appear like any other screw, other than that they are made of hardened steel that will cut its own thread in the masonry (Fig. 9). To install them, set the product in position and then drill the masonry behind it.
The hole can be any depth as long as it is much deeper than the length of the anchor. The big benefit of concrete screws over hammer anchors is that the screw can be eliminated and then reinstalled. You will lose some holding power if you do so, however. There are no set rules about which anchor to utilize in what situation, however the following standards will help: Machinery to a concrete flooring, As a guideline, you'll wish to use a heavy expansion anchor such as a sleeve or wedge anchor.

A deck journal on a masonry wall, Usage edge anchors on concrete or sleeve anchors into the horizontal mortar joints of a brick or block wall. Channel to a foundation wall, Use either hammer anchors or concrete screws.
If you're starting from scratch and there are no bolts, utilize either sleeve anchors or wedge anchors (Fig - Zinc-Plated Wedge Anchors. 11).
Other anchors are kept in location by powerful adhesives. While the amount of force these fasteners can withstand varies with their type, building and construction, and the qualities of the concrete, all concrete anchors are developed to stay in place even when positioned under a terrific deal of tension, making them tough to get rid of.
If the hole below the anchor is deep enough, some anchors can just be pounded into the ground. Others need to be split with a hacksaw or cut-off wheel, leaving an above-ground nub (Galvanized Wedge Anchors). Usually, that nub can be flattened with a hammer, although some larger nubs may need to be leveled with a grinding wheel.
Patrick O'Banion, Product Design Specializeds' founder, explains their origin: "I initially made this thing most likely seven years back. And the first one I made, I didn't have the ideal devices it was expensive - Wedge Anchors. So, I made it, and it worked well, but then I just hung it on my wall for probably about 3 or 4 years.
He says 'Male, we have actually got 500 of them that we require to break off. It's gon na' take us a week.' So, I loaned it to him. Well, the next day by midday, they called me up and stated 'Hey, Pat. We'll take two of them. And this other business's needs two of them.
Boltbreaker provides one the easiest, best, and quickest approaches on the marketplace for breaking off threaded rod. If something protrudes of concrete whether it's part of a concrete anchor or not it can be cut and prepped for concrete spot in a portion of the time used by other techniques.
