Correctly Using Washers and Bolts

Bolts and washers are pretty easy to use. They serve a simple purpose: Tightening and screwing just about anything. Indeed, you can use them to secure everything from alternators to wood beams. Despite this, it is possible to misuse bolt fasteners if you don’t know what you’re doing! Bolts and bolt washers need proper preparation and care before and during use.

You want to avoid problems while ensuring that the bolts provide a strong connection. To do so, we’ve provided a guide on the proper usage of washers and bolts. Using this information, you will be able to use them to get the exact results you need!

What Are Bolts and Washers?

Bolt washers are a small, flat discs, usually made of metal, but sometimes rubber and plastic. You insert this disc underneath the head of a bolt before fastening. When tightened, the washer’s function is to disperse pressure evenly between two items. In effect, it acts as a spacer or seal with the bolt fasteners.

The “bolt” in bolts and washers acts as a small fastener. It connects or joins up two surfaces or items. Metal usually makes up the material used in bolts. Bolts are also sometimes referred to as screws, though this is incorrect.

Bolt fasteners differ from screws in a few ways. For example, a bolt generally has threads and a flattened head and bottom. Screws mate with pre-made internal threading, or create their own threading. This depends on the design used.


Selecting the Right Bolt Fasteners

Stainless steel and galvanised steel make up the materials used in most bolts. You use these types in different types of projects. For example, you use galvanised steel washers and bolts in outdoor jobs. You use stainless steel for indoor tasks.

You’ll need to use the right type of material in bolts and washers, depending on the job. The bolt head will contain the information you need on the bolt materials and standards.

Sizing Bolts and Bolt Washers

You’ll need to correctly size the bolts and bolt washers to the mounting hole. The manufacturer’s documentation should contain information relevant to the mounting hole. Using this, you can find the right sized bolt fasteners for the hole. If you don’t know the hole diameter, try out different sized bolts until you find the right one.

You will also need to size the washers and bolts in a correct manner. The washer should fit around the bolt shaft, while sliding up to the head. Keep in mind, this should not be a snug fit.

Working With Bolts and Bolt Washers

For correct installation, you will first need to insert the bolt into the washer. Next slide the bolts and washers into the appropriate mounting holes. After threading the bolt into the hole, begin turning the head of the bolt. Tighten the bolt down to the washer until the head contacts the washer.

Use a torque wrench to tighten the bolt, if necessary. To do so, place the torque wrench over the head of the bolt. Then, turn it until the torque wrench pops and gives you a reading. This should ensure proper tightening for the washer and bolts.
