A 1B 9-Y641012 is a 12-tooth, 64-diametral pitch, 20° pressure angle brass pinion wire rod, 1 foot in length, with unfinished ends and an overall length tolerance of ±0.5 inch. It is sold as part of a series available in 1, 3, and 5 foot lengths, with pitch and pressure angle defined by the catalog code. The material is brass, as specified for this catalog number variant.
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.
