spring pin การใช้

• Coiled spring pins were invented by Herman Koehl circa 1948.
• Spring pins are designed for use in double shear applications.
• Typical materials for coiled spring pins include high carbon steel, stainless steel and alloy 6150.
• When coiled spring pins are installed, the compression starts at the outer edge and moves through the coils toward the center.
• The force exerted by the pin against the hole wall retains it in the hole, therefore a spring pin is considered a self retaining fastener.
• Spring pins have a body diameter which is larger than the hole diameter, and a chamfer on either one or both ends to facilitate starting the pin into the hole.
• In one, place ball ornaments, caps facing into the bowl to hide them, or tie a small bow with a color-coordinated ribbon onto the spring pin at the top of the cap.
• A coiled spring pin, also known as a " spiral pin ", is a self retaining engineered fastener manufactured by roll forming metal strip into a spiral cross section of 2 1 / 4 coils.
• One side of the cartridge is flat with title sticker, while the other side is sloped inward with notches on the left and right, which correspond to the spring pins on the main Datach unit.
• Coiled spring pins have a body diameter larger than the recommended hole diameter and chamfers on both ends to facilitate starting the pin into the hole, the spring action of the pin allows it to compress as it assumes the diameter of the hole.
