Countersunk Head Rivets

Countersunk rivets are a common mechanical fastener, primarily used for fastening applications requiring high strength and a smooth surface. Their countersunk head design allows them to sit flush with the workpiece surface after installation, eliminating any protrusions that could affect appearance or function. Countersunk solid rivets, on the other hand, are constructed from a single solid piece of material, without any hollow sections. They are typically used to connect workpieces professionally by hammering or riveting. There's also a countersunk head semi-tubular rivet, with a hollow section at the end for easier riveting and less labor-intensive than solid rivets.

Product Description

Introduction of countersunk head rivets

Countersunk rivets consist of a head and a shank. The head is conical with a flat top, designed to fit into a pre-drilled countersunk hole. The shank is cylindrical, and its end deforms during riveting to form a fixed head. Common materials include aluminum alloy, carbon steel, and stainless steel.

Aluminum countersunk rivets are lightweight and corrosion-resistant, making them suitable for applications in aviation, electronics, and other fields. Carbon steel countersunk rivets offer high strength and low cost, making them popular in construction and automotive structures. Stainless steel countersunk rivets combine strength and corrosion resistance, making them suitable for outdoor and humid environments.

Product Feature And Application

The riveting process for countersunk head rivets consists of three steps:

1. Drill a hole in the workpiece to be joined, creating a tapered hole that matches the countersunk head shape.

2. Insert the rivet into the hole, sinking the head into the tapered hole.

3. Use a rivet gun or hammer to compress the end of the shank, causing it to expand and form a second fixed head, thereby clamping the workpiece.

Countersunk head rivets are widely used in the following areas:

In machinery manufacturing, such as securing machine tool casings and transmission components. In the transportation industry, they connect aircraft skins and automobile chassis. In the construction industry, they assemble steel bridge structures and metal frames.
