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. Similar in function to split pins and linchpins, R-clips are re-usable and easy to remove.The tooling process occurs within a variety of different industrial fabrication settings. It also spreads out the stresses more evenly for a longer life. There is also a double loop variety when a wider range of suitable shafts is required. This angled end rides the side of the shaft and opens the "belly" mouth enough to pass the widest part of the shaft as the R-clip is inserted. To assist insertion the end of the bent leg is angled away from the straight leg. The straight leg of the R-clip is pushed into a hole near one end of the shaft until the semicircular "belly" in the middle of the other, bent leg of the R-clip grips one side of the shaft resisting any force removing the R-clip from its hole. R-clips are commonly used to secure the ends of round shafts such as axles and clevis pins. There is also the pin resembling the shape of the letter "R" Cotter Pin, also known as an R-clip, R-key, R-pin, hairpin cotter, hairpin cotter pin, hitch pin, bridge pin, spring cotter pin is a fastener made of a springy material, commonly hardened metal wire. Other kinds of Cotter Pins (also called R-clips) This can sometimes cause confusion, so the term split cotter is sometimes used for a split pin to help alleviate some of this confusion. "Cotter pin" as the British call them is the same thing as "cotter" to someone from the U.S.
