PINS
Pins are manufactured for fastening objects that are most often cylindrical. A pin is a device used for fastening objects or material together, and can have three sorts of body: a shaft of a rigid inflexible material meant to be inserted in a slot, groove, or hole (as with pivots, hinges, and jigs); a shaft connected to a head and ending in a sharp tip meant to pierce one or more pieces of soft materials like cloth or paper (the straight or push pin); a single strip of a rigid but flexible material (e.g. a wire) whose length has been folded into parallel prongs in such fashion that the middle length of each curves towards the other so that, when anything is inserted between them, they act as a clamp (e.g. the bobby pin), or two strips of a rigid material bound together by a spring at one end so that, when the spring held open, one can insert some material between the prongs at the other end that, the spring allowed to close, then clamp the inserted material. CE manufactures hollow, solid, and Split pins.
Hollow / Dowel Pins
Dowel pins are industrial fasteners that are used to join two or more items together. Hardened and precisely shaped dowel pins are used to keep machine components in accurate alignment. They are short, cylindrical rods made of various materials including wood, metal, and plastic. Dowel pins can be tapered, slotted, grooved, or otherwise altered to change their mechanical properties. Dowel pins are industrial fasteners that are used to join two or more items together.
They are commonly available in imperial or metric units. They also maintain precision alignment, ease insertion, absorb hole tolerances, and prevent interlocking. Hollow alignment dowels reduce weight and cost, plus simplify assembly. For a firm fit, the hole should be exactly the same size or slightly smaller than the dowel’s diameter. dowels are commonly used in furniture. They can also be applied as hinges and simple axles.

Solid Dowel / Spring Pins
Spring dowel pins are incredibly high strength pins that come with high durability and a long life expending for several decades. They are manufactured with a diameter slightly greater than the drilled hole through which it is to be inserted. The elasticity of these pins then applies a radial force across its length. Pins contain a slot that allows compression when inserted into the hole. The spring pin is used to assemble the parts without a screw. This makes it one of the most valuable and straightforward fastening systems in the market.
Hardened and precisely shaped dowel pins are used to keep machine components in accurate alignment; they are also used as location guides for adjacent machine parts and to keep the two sections of a punch and die in alignment. Because of their shock and vibration absorption capacity, and reusability they are used in many heavy-duty industries more economically. The automotive, aerospace, construction, and manufacturing industries rely on dowel pins to join different components of machines together to ensure proper alignment.
Spring dowels are used in applications where the dowel pins have to be disassembled from the location. The pins are incredibly versatile and can effectively replace bolts, washers, and retaining rings. But it can replace threaded components. These dowel pins due to their inherent “elasticity”, the property of it to get squeezed as inserted, make them a tight fit in a location. Due to the slit, any system fastened with these pins is resistant to vibrations and rapid movements without going through any wear and tear. But they can be easily taken out by compressing them again. All this possible due to the slit gave and the spring material it is made of.
At CE it is available in stainless steel, carbon steel, and alloy steel.
Split Pins
Splits pins are known as a roll pins. Split pins are commonly used to fasten a shaft or similar component in place. It is a piece of flat spring steel that is rolled where 2 edges are almost touching where. When it is forced into a hole the spring tension holds it fast. They are also used to keep machinery aligned. The split pin is placed through a hole and the tines of the pin are then bent to hold the pin in place
A split pin or a split roll pin is made from a harder grade of steel, such as spring steel. It is a narrow tube with a slit cut down one side. It is driven into a hole that intersects 2 parts, such as a pulley and a shaft. The hole is slightly smaller than the split roll pin. The pin compresses slightly upon installation and is driven in with a small punch, preferably a roll pin punch.
A split pin is a pin that once inserted through the hole has the ends turned back to prevent it from falling out. The split roll pin is the primary means of retention of the components. Without it, the components will separate.
