Definition
Pitch is the distance between three consecutive chain rivets divided by two. Chain pitch must match both the drive sprocket and the bar nose sprocket pitch.
Common families include 1/4", .325", 3/8" low profile, 3/8" standard, and .404". Similar naming does not mean interchangeability.
Measurement steps
- Identify three consecutive rivets on the chain and measure center-to-center from rivet one to rivet three.
- Divide that distance by two to get pitch.
- Cross-check with bar stampings and saw documentation before ordering.
- If any value is unclear, verify in Fitment Finder using model and bar details.
Common mistakes
- •Treating 3/8" LP and 3/8" standard as interchangeable.
- •Assuming pitch from bar length only.
- •Replacing chain without checking sprocket and bar pitch consistency.
Next step
Use your confirmed parameters in Fitment Finder, then submit an RFQ with pitch, gauge, drive links, and model details.
Compatibility and safe operation depend on OEM documentation, verified measurements, and local safety requirements.
