Copper Cotter Pins

Descriptions

Originally a ‘belt and braces’ device for industry for the prevention of unscrewing nuts from shafts and for restraining errant Clevis pins, the Cotter Pin has developed into numerous designs for newer applications in engineering.

Split cotter pins are crafted from robust wire, forming a semi-circular cross-section for added strength. Each pin features two separate legs connected at one end by a round head. When used, the pin is inserted into a pre-drilled hole—commonly found in shafts or bolts—until the head sits flush against the surface.

Using C101 Copper for Split cotter pins brings the following advantages:

Corrosion Resistance: Copper has a natural resistance to corrosion, and can withstand exposure to moisture, salt, and other corrosive substances without rusting or pitting.
Ease of Installation and Removal: Copper is relatively soft, which makes it easier to install remove, compared to harder materials.
Aesthetic Appeal: The natural copper color can also be desirable in certain applications where aesthetics is important.

Copper Split Cotter Pins are available from 1/32" to 5/16" diameter, lengths of 1/8" to 4" as standard, but other sizes may be available made to order, please contact us.
