Drive Screws & Knurled Pins
A permanent, press-in fastener typically used in the installation of non- removable name plates, warning placards and control panels. These fasteners can be installed with standard rivet setting equipment.
Shoulder Rivets & Collar Rivets
Shoulder rivets are typically installed so the shoulder acts as a bearing surface allowing the retained part to pivot. They are also used in bed frames and industrial storage racks as pins for interlocking keyhole assembly. Collar rivets are a variation of shoulder rivets and are often used as standoffs to separate components. Threads can be added to provide a terminal or stud.
Cross-Drilled & Grooved Rivets
These rivets provide positive mechanical retention of components while allowing easy removal by use of a cotter pin or snap ring as the retaining device.
Threaded Rivets & Inserts
Can be permanently installed or easily removed. Permanently installed rivets are often used as nut plates and can be open or close ended (see p. 6). Easily removable threaded rivets resemble screws except the threads are internal. When combined with an externally threaded rivet a binding post is created which can accommodate a wide variety of work thicknesses and provide lateral location of multi-layer components.
Milled-Head Rivets
A special milling process removes a portion of the head. Milled-head rivets can be used to solve clearance problems, or to provide a positive stop for locating the work piece.
Drilled Rivets
A secondary drilling process can provide a deep hole or a through-hole in the shank of a rivet. Examples of deep hole applications include receiving a wire lead in an electrical assembly, or as a weight reducing measure in a critical component. Another application for deep hole rivets is to pierce multiple layers of soft material such as leather without the need to pre-drill. Through- drilled rivets have been specified for use as air vents, or as stronger alternatives to eyelets in load bearing applications.
