What the SET BOLT does
Fasteners hold a machine together against continuous impact and vibration. On a percussion drill they are loaded components in their own right: bolts and studs are stretched to a specified tension, and it is that tension, not the thread, that keeps a joint together.
Signs it needs replacing
- Bolts found loose at service, or repeatedly needing retightening
- Stretched, necked or thread-damaged fasteners
- Fretting or witness marks around the joint faces
- Elongated bolt holes
Before you fit it
Replace stretched fasteners rather than retightening them, and always torque to specification in the specified sequence. A joint on a percussion machine that is not clamped to the correct tension will work loose no matter how tight it feels.
General guidance for this class of component. Always work to the torque figures, clearances and service intervals in your machine's own manual.
