CTS manufactures low-cost machine keys without sacrificing quality and dependability. Our machine key prices are ALWAYS lower than Grainger, Fastenal, GL Huyett, McMaster-Carr, Technifast, Fasteners Clearing House, Conex Metals, KIPP, FullerMetric, and Drillspot. If you find any "machine key" from these sellers, we will always beat their price.
Machine keys, also known as shaft keys, fasten shafts to gears, pulleys, couplings, wheels and similar parts. A machine key fits into the shaft's slot, or keyseat, and in the part's keyway slot, so they rotate together.
There are different types of machine keys. Parallel keys are rectangular, with their ends either square (DIN-6885-A standard), rounded (DIN-6885B standard), or square and rounded (DIN-6885-AB standard). Woodruff keys are semi-circular or half-moon keys with a flat or radius bottom. Machine key stock lets you make your own machine keys, sawing these longer pieces into whatever size keys you need.
Our machine keys are made with SC45 carbon steel or SS304 stainless steel. Special tapping, drilling and heat treatment services are also available upon request. If you require a machine key size, type, or metal not listed in our online catalog, please send us your desired machine key specifications with a drawing/diagram if possible and we will get back to you with a quote.
