There are a variety of different types of nut and bolt sizes, and choosing the wrong one can compromise its efficacy. The correct size depends on the type of job and the material to be used, thickness, and length. The quality of the nut varies from manufacturer to manufacturer. Some are more expensive than others, and you may want to look at the specifications of different types. You can find all of these information in this article.

stainless steel

Stainless steel nut and bolt is used for various purposes. The grade of these fasteners is a very important factor. If you are using them in automobiles, it would be better to choose bolts that have a grade of 316. Similarly, the bolts should have a nut and bolt head stamped with the letter "F" and the manufacturer's mark. You can also choose a nut and bolt that has no markings.

The nut and bolt should be of a different alloy if they are intended for similar applications. Stainless steel is a soft metal, so if it is not treated properly it can become corroded and lose its strength. Stainless steel nuts and bolts are not heat treated or thru-hardened. They have a clean silver color. You should avoid using them with aluminum and other materials that may result in corrosion.

eye bolt

The eye bolt is used to fasten a securing eye to a structure. It must be screwed in fully to ensure a secure fit. Its threads must be of equal length and the base material must be as strong as the eye bolt. Lifting eye bolts are manufactured as per DIN 580. They have a bent end. If you intend to lift something with the eye bolt, you should use shackles with the bolt.

When choosing an eye bolt, keep in mind that the working load limit is based on the vertical lift. Any angular lift will lower the limit. If you're lifting at an angle, use a shoulder eye bolt. You should never force a sling through an eye bolt. This will reduce the effective angle of lift and put pressure on your rigging. Another mistake to avoid is force through the eye bolt. This will change the angle of loading and reduce the strength of the eye bolt. Be careful not to force it through an eye bolt, as you might alter the angle of load or overload the sling. Also, you may have to tighten the eye bolt with a tool. The fitting should be free from any flaws.


A flange between a nut and a bolt is a special type of fastener that has a wider surface area under the head of the bolt. It provides even clamping pressure and acts as a washer. Flange bolts come in a variety of configurations, strength levels, and sizes. These fasteners are available in both metric and imperial measurements, making them an excellent choice for a variety of applications.

A flange between a nut and a bolt allows it to fit tightly into the nut or bolt and provides extra support. Flange bolts can be used with many different flange systems. Bolt sizes will depend on the physical size of the nut or bolt, as well as the number of boltholes. Bolt grade indicates how strong a bolt is typically required in high-pressure connections.

hook up

If you're not comfortable with using self-tapping hooks, a hook up nut and bolt is the perfect solution. Hook bolts have zinc plating to provide maximum corrosion resistance. This makes them an excellent choice in a variety of situations. The following is a look at some common types of hook up nut and bolts. Each type has its own specific use and environment. Listed below are the most common types.
