Square Key Steel 6mm x 12 Inch Length for Mechanical Engineering
Part No. 907 106
Overview:
The Square Key Steel 6mm x 12 Inch Length is a straight steel bar used to lock hubs to shafts for dependable torque transmission. With a 6mm square profile and a 12 inch (30.48 cm) length, it suits common metric keyways found in pulleys, sprockets, couplings, and flywheels. Supplied as bar stock, it can be cut to the required length and lightly chamfered for easy assembly. Made from durable steel, it offers a snug, positive drive between keyed components in machinery used across construction, agriculture, and garden equipment, as well as workshop and industrial drives. Ideal for maintenance and new builds where reliable, repeatable alignment and drive are needed. Manufacturer Part Number (MPN): 907 106.
