Enlarge your view of Bolts to know how they become stronger with the help of nuts and washers as anchors.

Nuts and washers are commonly used with bolts. There are three basic types of bolts which are carriage bolts, stove bolts, and machine bolts. There are also other types of bolts such as masonry bolt and anchor, toggle bolt, and expansion bolt. These are used to distribute weight when fastening something to a hollow wall. Machine bolts are made in two gauges: fine-threaded and coarse. Carriage and stove bolts are coarse-threaded. The size of a bolt is measured by shank diameter and by threads per inch, expressed as diameter by threads such as 1/4 X 20. Carriage bolts are available in lengths up to 10 inches, stove bolts up to 6 inches, and machine bolts up to 30 inches. Larger sizes usually require special orders.

Here are some of the common bolts to keep in your toolbox:

Carriage bolts have a circular head with a square collar and are commonly used in furniture making. They are secured with a nut and wrench and are coarse-threaded. Their diameter ranges from 3/16 to 3/4 inch with lengths from 1/2 inch to 10 inches. Stove bolts, on the other hand, are versatile and can be used for various fastening jobs. They have a slotted head, which can be oval, flat, or round and are tightened with a screwdriver or nut and wrench. They are coarse-threaded with diameters ranging from 5/32 to 1/2 inch and lengths from 3/8 inch to 6 inches. Machine bolts come with either a square or hexagonal head and are fastened using a wrench and either square or hex nuts. The bolt diameter increases with length, and they come in coarse-threaded or fine-threaded types. They are available in diameters from 1/4 inch to 2 inches and lengths from 1/4 inch to 30 inches. Masonry bolts and anchors work the same way as lag bolts or screws, while hollow wall bolts like toggle bolts and expansion bolts are used for fastening lightweight items to hollow walls. They are available in diameters ranging from 1/8 to 1/2 inch and lengths up to 8 inches for walls as thick as 1 3/4 inches.

1. What are bolts?

Bolts are fasteners that are commonly used in construction and manufacturing. They are designed to secure two or more objects together by passing through a hole and being tightened with a nut on the opposite side.

2. What are the different types of bolts?

There are many different types of bolts, including hex bolts, carriage bolts, lag bolts, eye bolts, and U-bolts. Each type has its own unique design and is used for specific purposes.

3. How do I choose the right bolt for my project?

When choosing a bolt, consider the material of the objects you are securing, the load capacity required, the environment the bolt will be exposed to, and any other specific requirements of your project. Consult with a professional if you are unsure which type of bolt is best for your application.

4. What is the difference between a bolt and a screw?

The main difference between a bolt and a screw is that bolts are usually used with a nut to secure two objects together, while screws are used to secure objects directly into a material, such as wood or metal.

5. How do I measure the length of a bolt?

The length of a bolt is measured from the bottom of the head to the end of the shank. Be sure to measure only the threaded portion of the shank, as this is the portion that will pass through the material being secured.

6. How tight should I tighten a bolt?

Bolts should be tightened to the manufacturer’s recommended torque specifications using a torque wrench. Over-tightening can damage the bolt or the objects being secured, while under-tightening can result in the bolt coming loose over time.

7. How do I remove a stripped bolt?

If a bolt becomes stripped, it can be difficult to remove. One method is to use a bolt extractor tool, which is designed to grip onto the stripped portion of the bolt and allow it to be turned out. Alternatively, a small hacksaw or file can be used to cut a slot into the head of the bolt, allowing it to be turned with a flathead screwdriver.

8. Can bolts be reused?

Most bolts can be reused if they are still in good condition and have not been over-tightened or damaged. However, it is always recommended to use new bolts when possible to ensure maximum strength and reliability.
