Description
Overview:
This Square Key Steel is a 1/4 inch (6.35 mm) square-section bar supplied as a 12 inch (30.48 cm) length. Made from durable malleable iron, it is used to lock a hub to a shaft so torque can be transmitted without slippage. Common across workshop, agricultural, construction, and garden machinery, it fits standard 1/4 inch keyways in pulleys, gears, sprockets, and flywheels. The bar can be cut to size and lightly dressed to suit the keyway for a precise fit. Strong yet workable, malleable iron offers good machinability and weldability for repairs and adaptations. A practical choice for maintenance engineers and DIY users, it provides a straightforward way to restore positive drive on worn or serviced equipment. Manufacturer Part Number: 907 014.
Key Features:
- 1/4 inch (6.35 mm) square section for widely used keyway sizes in shafts and hubs
- 12 inch (30.48 cm) length provides ample material for multiple small repairs
- Malleable iron construction for strength, impact resistance, and good machinability
- Aids reliable torque transmission between shaft and component, reducing slip and fretting
- Straight, square edges for a secure seating in parallel keyways
- Can be cut to length and lightly filed for final fit using common hand tools
- Suitable for workshop, site, and home use on garden and construction machinery
- Cost-effective single-length supply for maintenance and spares kits
- Simple to install: measure keyway, cut to size, deburr, and fit flush with shaft and hub
- Compatible with common applications such as pulleys, gears, sprockets, couplings, and flywheels
Typical Applications:
Used to replace worn or missing keys in drive assemblies on equipment such as lawn tractors, mowers, compactors, cement mixers, pumps, saw benches, and small industrial drives. Ideal for securing pulleys, gears, sprockets, and couplings to motor or gearbox shafts, restoring positive drive and alignment in general machinery maintenance.
Also known as:
Key stock, machine key, shaft key, square key bar, parallel key bar, key blank. These terms are commonly used in workshops and parts catalogues to describe the same square-section bar used for shaft-to-hub torque transmission.
