Module 4: Fasteners, Bearings, and Shafts
Most robot failures at competition are not broken parts. They are loose screws, worn bearings, and shafts that walked out of position. This module covers the hardware that holds everything together. Assemble joints that survive a full season of impacts and vibration.

What This Unit Covers
Read a metric fastener callout and choose the correct length, head style, and drive.
Prevent fasteners from backing out under vibration without making the robot impossible to service.
Support a rotating shaft properly and recognize the failure modes of an unsupported one.
Plan a spacer stack so a mechanism lands exactly where the design intended.
