What grade and material is the 1523001 hex bolt?

When should the 1523001 bolt be replaced?
Replace the bolt if you notice:
- Stretched, stripped, or damaged threads
- Cracks or shear damage on the bolt shank

Should I use a washer with the 1523001 bolt?
In many applications, yes. A hardened washer helps distribute clamping load and protects softer mating surfaces. Always check your service manual to confirm if a washer is specified for your particular assembly.
