All dimensions are in inches. American National Standard Spring Pins.— These pins are made in two types: one type has a slot throughout its length; the other is shaped into a coil. Preferred Lengths and Sizes: The preferred lengths and sizes in which these pins are nor mally available are given in Table 10 and Table 11. Materials: Spring pins are normally made from SAE 1070-1095 carbon steel, SAE 6150H alloy steel, SAE types 51410 through 51420, 30302 and 30304 corrosion resistant steels, and beryllium copper alloy, heat treated or cold-worked to attain the hardness and performance characteristics set forth in ANSI/ASME B18.8.2-2000 (R2010). Designation: Spring pins are designated by the following data in the sequence shown: Examples: Pin, Coiled Spring, 1 ∕ 4 × 1 1 ∕ 4 , Standard Duty, Steel, Zinc Plated Pin, Slotted Spring, 1 ∕ 2 × 3, Steel, Phosphate Coated
