Pinion wire stock in brass, 48 pitch, with 20 teeth and a 14-1/2° pressure angle, is sold in 1-foot lengths with unfinished ends and an overall length tolerance of ±0.5 inch. The pitch diameter is 0.417 inch and the outer diameter is 0.458 inch.
The material of pinion wire is dragged through the dies; it is referred to as "drawn" steel, a process that begins with melting several metals together, typically iron plus an additional metal type that is a crucial part of the alloy (smelting). After being slightly cooled, the metal is then coated with a drawing lubricant and pulled through the dies, which form its teeth. The metal cannot be dragged through the dies that shape it without this lubrication.
When a stock gear is not available, spur gears can be made using SDP/SI pinion wires. Available in the following pitches: 64, 48, 44, 32, and 24 (modules 0.4, 0.5, and 0.8) in steel and brass. Other lengths are available upon request.
Steel spur gear stock is also offered in pitches 48, 32, 24, and 20 (modules 0.8 and 1) and is used to make spur gears.
