💡 How do you pick the right set screw length for a mounting job? Nailing the length keeps your rig tight and saves you from stripped threads.
- Match thread length to roughly half the width of the bushing bore
- Cup point tips are handy for locking onto machined shafts directly
- Drive with a hex key until the fastener bites hard before testing
