cotter pins?
Split cotter pins are commonly used in mechanical applications to secure fasteners such as bolts and nuts. They provide a reliable and secure way to prevent loosening or disassembly of components. The benefits of split cotter pins include easy installation, high strength, and resistance to vibration and movement.
Bike cotter pins are small metal pins used to secure the crank arms to the bottom bracket axle of a bicycle. They play a crucial role in maintaining the connection between the crank arms and the axle, ensuring that the pedals can turn smoothly and efficiently. Without cotter pins, the crank arms could become loose or fall off, leading to a loss of power and control while riding. In essence, cotter pins help to keep the bike's drivetrain functioning properly and ensure a safe and smooth riding experience.

It is a cotter key or cotter pin (not carter). In the United States, cotter pin (also known as a cotter key[1] or a split pin) is a metal fastener with two tines that are bent during installation, similar to a staple or rivet. Typically made of wire with a half-circular cross section, cotter pins come in multiple sizes and types.
Split pins, also known as cotter pins or cotter keys, are typically made of metal, commonly steel, due to its strength and durability. They may also be made from stainless steel or brass for corrosion resistance in specific applications. The metal is often treated or coated to enhance its resistance to rust and wear. The design allows for flexibility, enabling them to secure components effectively by spreading the ends after insertion.

Castellated nuts are used with bolts that have holes drilled in them for cotter pins or safety wire. To torque one, first you bring the fastener to the published torque...say it's 90 lb-ft. You then tighten it just enough more to make the holes accessible to the cotter pins or the safety wire, and install the locking device.
You have to buy them.
Most cotter pins are bent at one end and a loop at the other. You have to straighten the bent ends and grab the other end with a pare of vice grips and pull . If it will not come out you may have to brake off the end of cotter pin and punch it out with a fine punch (some times you can use a small nail).
They weren't glued. They shaped the logs to fit together and where necessary pinned them with wood 'cotter pins' .
