There are so many kinds of bolts, but Fasteners, Inc. can help you get to know your bolts and their many uses. Basically, a bolt is a small metal rod with threads and a head and it uses a nut fastener with a threaded hole to assemble two unthreaded components.
It may seem simple, but there are many different kinds of bolts for a variety of applications. According to a Mechanical Buzz article, here are some bolts and their uses.
A glue-in bolt has superior strength and is the longest lasting. It can be used for soft and hard rocks where stress corrosion cracking is a concern. If the hole is bigger than the bolt some glue can be placed along the hole to give a tighter grip on the bolt. If you glue it, once the bolt is in place it cannot be removed.
A sleeve bolt is a stainless steel five-piece powers bolt. It comes in ⅜ inch and ½ inch diameters. This plated steel bolt can be easily replaced. It has a hex bolt head and the longer bolt has two sleeves but is still called a five-piece bolt. It has more strength than a wedge bolt.
Petzl Long Life Bolt
A Petzl long-life stainless steel bolt is a ½ inch in diameter and 2 inches in length. It has a steel pin set in the shaft. It is a strong bolt and lasts long but is not safe in medium to soft rock.
A wedge bolt is a power stud stainless steel bolt or a non-stainless steel double sleeve stud bolt. It has a threaded shaft and nut with a small clip at the top which holds the nut and shaft tight. It comes in ⅜ inch and ½ inch diameters. A wedge bolt is weaker than the sleeve bolt and can make more errors as they deform.
There are two types of sheath bolts. The Star Dryvin bolt has a star printed on it. The Taper Bolt has a stud sticking through it and hex head with no threads.
A compression bolt is called a button head because the tail end of the bolt resembles a button. It is 1 ¼ inches to 2 inches long and a 1/4 inch in diameter. It has split shafts to hold the hole when it’s hammered. It has a force fit. Hammering it makes the split shafts come together at the place of contact with the holes to get a strong grip.
Not used much anymore, a self-drill bolt has a large machine bolt head. It actually acts like a drill bit which is pretty handy.
