These pins use spring force to hold pieces of telescoping tubing together. Install them in the smaller tube, then slip the larger tube over the smaller tube until the button pops into a hole. Also known as snap buttons and tubing buttons.
Zinc-plated steel pins offer good strength and some corrosion resistance.
410 stainless steel pins resist wear as well as corrosion. They are magnetic.
301 stainless steel pins are the most corrosion resistant. They may be mildly magnetic.
