Taper Washer: What is it, and how to use it?

Hello, everyone. Today, I would like to introduce you to a useful washer called “Taper washer”. A taper washer is a washer that has a square or half-round shape with one side sloped, and it is used to fix parts to the base material such as concrete or steel plate. A taper washer has the feature that it can make the bolt assembly fit flat on the tapered face of the steel joists, such as C-sections or I-sections. A taper washer is used in various construction works, such as building construction, machine installation, and so on.

The types and benefits of taper washers are as follows:

Square taper washers: Square taper washers are taper washers that have a square shape, and they are used for U-sections or channel sections. Square taper washers can match the 5° taper shape of the inside of the channel sections, and make the bolt or nut flat. Square taper washers are made of materials such as iron or stainless steel. You can find the product information of square taper washers here.
D-shaped taper washers: D-shaped taper washers are taper washers that have a half-round shape, and they are used for I-sections or I-beams. D-shaped taper washers can match the 8° taper shape of the inside of the I-sections, and make the bolt or nut flat. D-shaped taper washers are made of materials such as iron or stainless steel. You can find the product information of D-shaped taper washers here.

The following is the explanation of how to use taper washers:

To use a taper washer, first, you need to drill a hole in the base material. The size of the hole should match the size of the taper washer. The depth of the hole should be about half of the height of the taper washer.
Next, you need to insert the taper washer into the hole. You need to align the sloped side of the taper washer with the tapered face of the steel joist, and push it in. You need to make sure that the taper washer fits snugly into the hole, and rotate the base material while pushing it in.
Finally, you need to attach the part to the taper washer. You need to place the part on the taper washer, and secure it with a bolt or a nut. You need to adjust the position of the taper washer so that the part does not move relative to the base material.
