The other end of the pin contains a drilled hole extending through the width of the pin. The Clevis Pin contains a head resembling a nail head on one end. The pin will compress to permit an operator to slip it into a pre-drilled hole of a slightly smaller circumference than the pin once installed, the walls of the pin continue pressing against the sides of the hole.Ĭlevis Pins: Manufacturers designed these removable pins to help secure two items together in conjunction with a Cotter Pin. Slotted Spring Pins: These fasteners consist of hollow cylinders of metal containing a single longitudinal slot along one side. They remain flexible under the stress of shifting loads and have been widely used in automotive vehicle door handles. Spirally Coiled Spring Pins: These metal pins invented in the late 1940s consist of coiled spring surrounding a hollow interior. The pressure of the compressed sides of the pin against the wall of the hole allow the Spring Pin to remain in place. Spring Pins: These pins, sometimes called “tension pins”, will expand during use in order to fit snugly within a pre-drilled cavity. They play a useful role in many furniture assemblies since they will insert easily with the application of pressure. S olid Tapered Pins: These solid cylindrical pins taper uniformly on one end. For example, a Solid Cylindrical Pin may fit inside a drilled slot in order to secure a removable drill bit. Solid Cylindrical Pins: Cylindrically shaped solid pins, these types of fasteners frequently help hold machinery in correct alignment. For example, they may serve as a fulcrum pin in nozzles of sprinklers. Usually stronger than Spring Pins, these pins perform a variety of applications. Hammers or hydraulic presses permit the forcible insertion of Groove Pins into place. Manufacturers can join items with these pins by sliding the pin into a pre-drilled hole containing a projection designed to insert longitudinally inside the groove. Groove Pins: A specialized form of Dowel Pin consisting of solid pins containing specifically-sized longitudinal grooves, Groove Pins enjoy widespread popularity. Manufacturing companies today rely upon hundreds of unique fastening systems, some of them in the public domain and other proprietary in nature.ĭowel Pins: Typically utilized in conjunction with adhesives, Dowel Pins formed from wood or metal permit manufacturers to affix assembled components securely within pre-drilled holes. Some, such as screws, typically rely upon threads to help accomplish this goal. Mechanical Fasteners: A multitude of devices help create semi-permanent couplings of industrial components. Some of the most popular types of pins today find wide application in many industries: Pins may perform coupling tasks as versatile as helping secure a drill blade in place during operation, or join two dissimilarly-shaped constituents within an assembly. Inventors have created a number of different types of pins to assist manufacturers in performing specific fabrication and assembly tasks. Shear Pins, perform limited yet highly specific coupling tasks. Certain pins, such as Spirally Coiled Spring Pins, offer flexibility in the wake of heavy use. Ultimately, the best design may depend upon the pin’s intended purpose. While some pins serve a temporary fastening function, other pins provide enduring fastening capabilities. Inventors have developed a variety of industrial pins to perform different types of coupling and fastening tasks. The constituent pin materials and the design of a fastening system sometimes vary widely. These useful devices perform functions which may range from permanently securing two or more components together to helping two items placed in alignment maintain position for variable periods of time. Modern manufacturing enterprises depend upon a wide variety of metal fasteners and pins. Devices called “pins” help companies couple work pieces by aligning, fastening or otherwise joining them together. Manufacturers often rely upon devices intended to assist the production process during tooling, such as jigs, fixtures, templates, patterns and dyes. The tooling process occurs within a variety of different industrial fabrication settings.
