Custom Bolt
Mechanical parts called “fasteners” assist in affixing items together securely. These components, which include bolts, screws, rivets, clasps, buttons, and other fastening systems occur today in a multitude of forms. Manufacturers sometimes purchase fasteners by choosing products with dimensions suited to their brands. However, many manufacturers obtain bespoke or custom fasteners designed for the sole purpose of securing specific designated parts together.
About Bolts
Traditionally, manufacturers describe mechanical metal coupled fasteners as “male” and “female”. This terminology (which obviously does not refer to gender in this context) promotes easier assembly by preventing confusion. Female parts contain holes or receptacles, while opposite male parts often include threads, ribs, or projections. Manufacturers can more easily refer to paired components because the use of the female or male descriptors implies a two-part fastening system consisting of separate yet distinct sections which help secure an object by acting in unison.
One popular type of mechanical fastener, a bolt, bears strong similarities to a rivet yet frequently contains a ribbed shaft designed to hold a female nut. Many modern manufacturers don’t draw a firm distinction between bolts and screws anymore, although the former typically contain ribs, not threads, and should include a nut or other female component and not function as a single fastening device. The proximal end of the bolt (which generally contains a square, circular, or hexagonal head) strongly resembles a rivet. Bolt-and-nut fastening systems achieved popularity because manufacturers can tighten them in place from the distal end after inserting them through two compatibly-sized drilled apertures.
Fastener Supply
Today bolts often join items made from rock, metal, wood, concrete, plastic, or other materials. Bolts differ from screws because a screw’s exterior male threads frequently (but not always) extends along the entire body of the part. The thread tapers into a point at the distal end designed to penetrate into the surface of a joined material (frequently wood). By contrast, most bolts require nuts in order to fasten securely, they don’t self-thread.
