Machine Keys
Parallel keys are uniform cross-section mechanical fasteners that lock rotating components to shafts for reliable torque transmission. Fabricated predominantly from high-strength carbon or alloy steels, they are designed to withstand continuous shear forces without deforming. These standardized elements are ubiquitously utilized in heavy machinery, electric motors, and power transmission assemblies requiring high load capacities.
Our parallel keys are available in a range of sizes, materials, and standards. Contact us for a detailed specifications sheet and competitive bulk pricing.
