Growing Utility of Dowel Pins and Cotter Pins

·        

Pins are widely used in manufacturing machinery and other production plants, especially to fix collars and pulleys to the shafts. There is a long list of choices in this category such as dowels, grooved pins, spiral pins etc. Most commonly used are Dowel ins and Cotter Pins.

Dowel Pins

Dowel pins are used as pivots, hinges, shafts, and fixtures to grip parts. For a tight fit, your hole should be equal to or slightly lesser than the diameter of the pin. Its tensile strength is measured as double shear, which is the force required to break a pin into three parts.

Materials

Stainless Steel pins are the strongest dowel pins. Pins with a black-oxide finish have some sort of corrosion resistance. Stainless steel pins are more corrosion resistant than ordinary steel pins. Pins that are passivized, offer added protection against corrosion and oxidation.  316 stainless steel pins have the best corrosion resistance. They may be mildly magnetic in nature. 

·400 nickel pins and the grade 2 titanium pins resist saltwater and the caustic chemicals. 400 nickel is also known as Monel, may be mildly magnetic. Titanium pins are about as strong as steel pins but are 40% lighter than them. They are not magnetic in nature.

Brass pins are somehow softer than other materials, so they’re often used as shear pins. They resist corrosion and are nonmagnetic in nature.

Aluminum pins are one-third the weight of stainless steel pins, but not as strong as them. They resist corrosion and are nonmagnetic in nature.

Standards

Pins that meet ASME B18.8.2 specifications conform to ASME standards for material and dimensions, and pins that meet MS16555 specifications conform to military standards for material and dimensions. Metric pins meet either DIN 6325-m6 details for steel pins or ISO 2338-m6 determinations for stainless steel pins. DIN 6325-m6 is practically proportional to DIN EN ISO 8734, with slight contrasts in hardness and length resilience.

DIN 7 is not, at this point a functioning determination and is supplanted by ISO 2338-m6. They are practically proportional with slight contrasts long and the pin closes. DIN 7 has adjusted ends where ISO 2338-m6 has chamfered ends.

Cotter Pins

Cotter pins are also known as split pins, these have one prong slightly longer than the other so they’re easy to open. Bend prongs outward to secure your materials. Use them to secure the ends of clevis pins and shafts to keep components in place.

Materials

Stainless Steel cotter pins have good strength and durability. Pins having a zinc-plated finish are corrosion resistant. Pins with a cadmium yellow-chromate plated finish have good corrosion resistance and meet MS24665 for dimensions, material, and finish.

18-8 stainless steel cotter pins gives a balance of strength and corrosion resistance. They may be mildly magnetic in nature. Passivized pins give added protection against corrosion and oxidation.

316 stainless steel cotter pins have the best corrosion resistance of our stainless steel pins and are as strong as 18-8 stainless steel pins. They may be mildly magnetic in nature.

Aluminum cotter pins are one-third the weight of stainless steel pins and are also corrosion-resistant. They are nonmagnetic.

Brass cotter pins are rust-resistant, electrically conductive, and nonmagnetic.

400 nickel cotter pins are strong and wear-resistant. They withstand saltwater and caustic chemicals and may be mildly magnetic. They are also known as Monel.
