Niittipistooli

Niittipistooli, also known as a rivet gun or rivet tool, is a mechanical fastener tool used to install rivets. Rivets are a permanent mechanical fastener, consisting of a smooth cylindrical shaft with a head on one end and a tail on the other. The rivet is placed through a hole in the materials being joined, and the tail is deformed ("bucked") to create a second head, thus clamping the materials together.

There are several types of niittipistooli, including manual, pneumatic, and electric. Manual niittipistoolit are operated by hand and are suitable for lighter-duty applications. Pneumatic niittipistoolit use compressed air to drive the rivet, making them faster and more efficient for repetitive tasks or larger rivets. Electric niittipistoolit, powered by batteries or mains electricity, offer a balance of portability and power.

The process of using a niittipistooli generally involves inserting the rivet into a pre-drilled hole, placing the niittipistooli's nosepiece over the rivet's head, and then activating the tool. The tool pulls on the rivet's stem, breaking it off at a pre-determined point and simultaneously deforming the tail to create a secure joint.

Niittipistoolit are commonly used in various industries, including automotive manufacturing, aerospace, construction, and metal fabrication, for assembling everything from aircraft components to sheet metal ductwork. The choice of niittipistooli and rivet type depends on factors such as the materials being joined, the required strength of the connection, and the working environment.
