A nut is a type of fastener with a threaded hole.

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.

Types of Bolts - A Thomas Buying Guide

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.

Bolt (fastener)

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.

Posted on October 25, by mike. BoltDepot has a great selection of charts used to identify and explain the wide variety of screws, bolts, nuts, washers and other pieces used for building just about every project you can imagine. Wood screws, machine screws, carriage bolts, lag bolts, square heads, torx, ogee washers and more. Very handy indeed. Both nuts and washers are sized by the fastener they fit.

Fastener options are almost limitless. The various shapes and sizes and the practical uses for each different type can be confusing. To get more specific, the differences between a screw and bolt are almost zero. In regards to bolts, the types range from the fairly common hex bolt to the more unique hanger bolt. Below is a description of a few different bolt head types and how they can be applied. Hex bolt: a bolt with a hexagonal head and machine threads for use with a nut or in a tapped hole.

Nut (hardware)

But while they look similar — and have similar characteristics — they are two unique fasteners with their own unique applications. In comparison, screws are used to assemble objects with threads. Some objects feature pre-made threads, whereas others create the thread during the installation of the screw. So, the fundamental difference between screws and bolts is that the former is used to assemble threaded objects, while the latter is used to assemble untreaded objects. With that said, screws can make their own threads during the installation process.

A bolt is a form of threaded fastener with an external male thread requiring a matching pre-formed female thread such as a nut. Bolts are very closely related to screws. The distinction between a bolt and a screw is poorly-defined. The academic distinction, per Machinery's Handbook , [2] is in their intended design: bolts are designed to pass through an unthreaded hole in a component and be fastened with the aid of a nut , although such a fastener can be used without a nut to tighten into a threaded component such as a nut-plate or tapped housing.

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.

Пожалуй, я все же оставлю ей записку.  - И он положил конверт на стойку. Консьерж взглянул на конверт и что-то грустно пробормотал себе под нос.

 Выключите, - приказал.  - Выключите эту чертовщину. Джабба смотрел прямо перед собой, как капитан тонущего корабля. - Мы опоздали, сэр. Мы идем ко дну.
