Keystone - Inserts are a specialized type of fastener used primarily for installation in metal surfaces. They provide a secure and permanent joint between the two parts without welding or brazing.

The most common type of keystone inserts consists of a thin, flat metal plate with small protruding teeth on one side. These teeth bite into the metal surface creating a secure and permanent bond. The other side is typically designed with a grooved surface that allows for easy installation with a screw or bolt.

Keystone inserts offer many advantages over traditional fasteners such as bolts, screws, or rivets. They are faster and easier to install, require no special tools or skills, and require no welding or brazing. In addition, keystone inserts provide a better seal than other fasteners because the teeth extend all the way through the metal surface.

Keystone inserts are most commonly used in the automotive, construction, and manufacturing industries. They are ideal for applications where a secure, permanent bond is required such as joining sheet metal or attaching metal plates to frames. The most common applications include vehicle body panels, suspension components, and engine parts.

The working principle of keystone inserts is simple and efficient. When the teeth are pushed into the metal surface they create a mechanical lock, preventing the insert from being pulled back out. The grooved surface on the backside of the insert helps to ensure an even and secure bond between the two components.

Keystone inserts are an ideal solution for applications that require a secure, permanent bond that can’t be accomplished with traditional fasteners. They are fast to install, require no welding or brazing, and provide a better seal than other fasteners. Keystone inserts are an invaluable tool in the automotive, construction, and manufacturing industries.
