If you’re the type of person who spends a great deal of time working on construction projects for work or around your home, you probably know the basics about screws/bolts, nuts, washers. You may know that screw sizes are indicated by numbers, with the width and thickness of the screw corresponding to a higher number. You also might know that certain screw threads are designed to mate with a complementary thread, called an internal thread. And, that the pitch of a screw, or the degree of its thread, is also specified by numbers.
However, when it comes to specialty nuts and bolts, from steel anchor bolts to metric hex nuts, you may find yourself out of your element. After all, what types of things fall into the category of specialty bolts and nuts?
While metal screws were first used to fasten objects together in the 15th century, the technology has improved in a number of ways. Today, the U.S. screw, nut and bolt industry employs an estimated 118,998 people, with a significant portion of the industry's operations being dedicated specifically to specialty screws and bolts and nuts. Because of this, it’s now possible to find almost any required piece, ranging from steel anchor bolts to hex head cap screws. Some of the most commonly sought screws, nuts and bolts include lag screws or lag bolts, which are used as large wood screws; square-drive screws, which were invented by Canadian P.L. Robertson in 1908; and drive screws, which use a screw thread to deliver power.
If you’re working on a project that requires specialty nuts and bolts, it’s necessary for your safety that you use the correct size and model screw in your work. Likewise, if you are using a certain type of screw or bolt, it’s important that you use the corresponding screw. Because the pieces are designed to work together, not doing so can cause accidents and put your safety at risk. Therefore, if you find yourself in need of steel anchor bolts, corresponding nuts, or any other specialty piece, you should contact a bolt and nut manufacturer or a bolt and nut supply company to find the nuts and bolts you need.
