Precision Key Steel at AIMS Industrial
Key steel (also called machine key stock or feather key stock) is a precision-ground engineering material used to create the key and keyway connections between shafts and hubs — ensuring positive drive transmission in pulleys, sprockets, gears and couplings. AIMS Industrial stocks Precision brand key steel across a broad range of profiles and materials for workshop and engineering use.
Precision Key Steel at AIMS
The Precision key steel range at AIMS is available in multiple profiles and materials:
- Metric Square Key Steel — low-carbon steel, standard metric dimensions
- Metric Rectangular Key Steel — low-carbon steel, metric cross-sections
- Imperial Square Key Steel — low-carbon steel, imperial dimensions
- Imperial Rectangular Key Steel — low-carbon steel, imperial cross-sections
- Metric Square Key Steel — 304 Stainless Steel — for corrosion-resistant shaft assemblies in food, marine and chemical applications
Machining and Fitting Applications
Key steel is typically supplied in lengths suitable for cutting to size in the workshop. The precision ground dimensions ensure a correct fit in standard keyways without excessive fitting work. Having a selection of metric and imperial sizes on hand reduces delays during shaft assembly and maintenance.
