Parallel Keys with Step Bores for Fixation Screw
Product Overview
Parallel Keys with Step Bores for Fixation Screw are essential mechanical components used to connect rotating machine elements such as gears and shafts. These keys securely fasten components to prevent motion between the shaft and the hub during rotation. What sets these keys apart is the integrated stepped bore that enables easy accommodation of fixation screws, ensuring additional stability and alignment. Parallel Keys with Step Bores for Fixation Screw are designed for high-precision applications and are a critical component in various power transmission assemblies.
At Flybear Fastener, we specialize in providing a wide range of precision machined fasteners, including these high-performance parallel keys that meet stringent industrial standards.
