Types of Bolts, Nuts, and Washers | A Complete Guide on Fasteners

It might be unusual to think of bolts and nuts as cutting-edge technology, but for at least 1, years these fasteners were nothing less. Until the Industrial Revolution, the six classical machines were responsible for every mechanical advantage. Of the original six machines, screws were likely the last to be invented, but also the most revolutionary. Screws were effective as gear reductions in worm drives. Most importantly, they could assemble materials reliably and proficiently. After all, most compound machines are hybrids of simple machines.

Bolts are a form of mechanical fastener that is designed with external threads and paired with a nut which is intended to be inserted through holes and use to join parts together using tightening torque. Unlike screws, which are also externally threaded fasteners, bolts require a nut to be able to function properly and require a drilled hole into which the bolt may be inserted. Bolts are produced to a series of standards that assure uniformity in the dimensional characteristics and materials. These parameters include:. For related information on screw fasteners, consult our guide covering types of screws. Anchor bolts are bolts that are designed to be used to attach a structural member or component to a concrete slab or poured foundation. Anchor bolts may be preset into place while the concrete structure is being cast, as with the plate used on top of the poured foundation of a house.

Fasteners come in many different forms. Scroll down to learn about many different types of nuts, bolts and screws! Screws use their threads to provide their own holding power. The terms in the industry are commonly mixed so sometimes you will see something that is called a screw or a bolt that is actually the opposite. Example: Lag Bolts and Lag Screws are the same thing. We have broken them down according to their true definition. The square section under the head grips into the part being fastened preventing the bolt from turning when the nut is tightened.

Nut (hardware)

A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction with slight elastic deformation , a slight stretching of the bolt, and compression of the parts to be held together. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers , jam nuts , specialist adhesive thread-locking fluid such as Loctite , safety pins split pins or lockwire in conjunction with castellated nuts , nylon inserts nyloc nut , or slightly oval-shaped threads. Square nuts, as well as bolt heads, were the first shape made and used to be the most common largely because they were much easier to manufacture, especially by hand.

All fasteners perform the same function—mechanically joining and securing two or more parts together.

Bolt Threads

For Flat Head - Measure length from the top of the head to the end of the screw. Socket screws, also known as Allen Head, are fastened with a hex Allen wrench. Bolts with a hexagonal head with threads for use with a nut or tapped hole. Bolts in U shape for attaching to pipe or other round surfaces. Also available with a square bend. Thread Cutting Machine Screws Machine screws with a thread cutting self tapping point. A bolt with a circular ring on the head end.

In this article, you will learn about the types of nuts and bolts. A bolt contains two parts a shank and head. The cylindrical portion of the bolt is known as the shank. The shank is threaded at the tail end for a sufficient length so as to effectively engage with a nut. The shape of the head is depended upon the purpose for which bolt is required. The nut is a type of a fastener which has a threaded hole in it. The hexagonal head is chamfered at its upper end.

Bolts belong to the family of threaded fasteners and are paired with a threaded nut when in use, usually to join two or more components together. Bolts are classified into different types according to their distinct head shapes, strengths, finishes and materials. Types of bolts and their uses. These classifications all play a role in the final selection of a bolt type for a certain application. It is imperative to have the required knowledge to choose the correct bolt type for a specific job at hand, as there are various styles of bolts that are more effective than others. Bolts as well as screws are available in a vast variety of head shapes. These heads are made in order to grip the tools that are used to tighten them.
