Solid rivets consist of a solid cylindrical shaft with a "head" on one end which might be round, flat or countersunk.
Their length depends on the thickness of the materials being joined.
Solid rivets are used in applications requiring high reliability and safety. Aircraft structural parts are a typical application for solid rivets (most of the rivets used for this type of application are made of aluminium alloy, titanium or nickel-based alloys such as Monel metal, and with dome or countersunk head). Solid steel rivets are used in static structures such as bridges, cranes and building frames. They have a radial deformation and usually fill out the hole which restricts motion.
