Construction Screws | Copper State Bolt and Nut Co.

There are some items that are indispensable, on any construction site. One such item is construction screws. This single item comes in an array of shapes and sizes, all designed for a specific task. If you’re into construction, you will no doubt run into a situation that requires construction screws of one type or another. In some cases, you might find that the type of screws you need are not readily available, so you’ll need to look for a company, like Copper State Bolt & Nut Co., that specializes in construction screws.

The following is a list of specialty screws you might have a hard time finding:

1. I-lag Screws: designed for construction jobs that require a screw tough enough to burrow through multiple layers of construction material. Normally, this screw is used to penetrate walls that have two outer layers of drywall, backed by 16-22 inch heavy gauge sheet metal. The “eye” in the head of the screw is used to support equipment like wiring and ventilation mounts.

2. Flat-head Phillips masonry screws: found at almost every construction site, in one form or another. These screws do more than just burrow into the masonry; they expand as they go in, creating a super-tight fit that prevents them from coming loose later on.

3. Hex-head masonry screws: these work on the same principle as the Flat-head Phillips screws, except they feature a uniquely-designed head that facilitates wrenches—or a drill outfitted with a wrench socket. This screw also expands as it burrows into masonry, creating an unshakable grip.

4. Hex-head structural bolts: designed for steel-to-steel connections. They are distinguished from your regular bolts by their characteristic, super-sized heads. The larger head gives them extra strength and makes them ideal for steel-frame buildings where they can be expected to bear the brunt of the structure’s weight, like with the heavy steel beams used as the backbone of most skyscrapers.

5. Tension control bolts: this bolt is also used in heavy construction, but unlike its cousin, the hex-head bolt, it has a beveled head and, therefore, is not meant to be driven in. Rather, it supports a nut that is tightened to secure the connection. The bolt is prevented from turning by its squared shaft and matching hole.
