What is a Rivet?

Rivet Description

A rivet is an unthreaded fastener that uses expansion to clamp materials together and form a secure bond. Rivets consist of a head and a tail or shank. Rivets are fabricated from many different types of material but aluminum alloys tend to be the most popular particularly for aerospace applications.

Rivet Installation

During installation rivets are inserted into pre-drilled holes and the tail/shank is compressed, deforming it and creating what amounts to another head. The compression of the tail/shank also causes the rivet to expand in the hole thus helping to bind the materials together. Blind rivets, often called pop rivets, use a mandrill (a long shaft that protrudes from the head) to compress the tail/shank. The mandrill is pulled out through the head to compresses the tail/shank and is then snapped off. Blind rivets allow installation without requiring access to the rivet tail. Depending on the style of rivet, installation is accomplished using a hammer or a rivet gun.

Rivet Uses

Although in existence for centuries, rivets gained popularity among manufacturers during World War II. Today rivets are used to in all kinds of applications including buildings, bridges, aircraft, vehicles, medical equipment, robotics, and industrial machinery.  Rivets are prized for their light weight, permanent installation, and high shear strength (support of loads perpendicular to the axis of the shaft).

Rivet Types

  • Solid Rivets
  • Semi-Tubular Rivets
  • Blind Rivets (Pop Rivets)
  • Oscar Rivets
  • Drive Rivets
  • Flush Rivets
  • Friction-Lock Rivets
  • Self-Pierce Rivets

What is a Locknut?

A locknut is a nut specifically designed to stay fastened despite vibration or other environmental stresses.  In order to stay locked in placed locknuts utilize surfaces that increase friction and reduce the possibility of the nut coming loose.  The most common way to increase the surface friction is to add a nylon patch to the locknut’s threads. In some cases friction is also increased by fabricating locknuts with a slightly oval shape.  Locknuts come in in various types including jam nuts, speed nuts, flex-top locknuts, distorted-thread locknuts, and castle nuts.

Locknut Applications

Needless to say, high quality and reliable locknuts are integral to many applications. Some of the most popular applications for locknuts are aircraft, military equipment, and machinery. These applications typically experience high stress and it is critical for safety and performance that components stay securely fastened.

Locknut Suppliers

Popular locknut brands include SPS Flexloc, MacLean ESNA, Micro Plastics, and Republic (Alcoa). Thanks to companies like Nylok standard nuts can also be converted into locknuts by adding a nylon patch. For more detailed locknut specifications and technical info view MacLean ESNA’s Catalog.
