ALNd — UNC Class 10 (Double-Slotted All-Metal Lock Nuts)
Steel Class 10 prevailing-torque nuts per ISO 2320 for UNC threads. Clear Zinc finish as standard. Engineered for repeatable assembly, low prevailing torque, and reliable re-use.
- Material grade: Steel Class 10 (hardness per ISO 898-2).
- Finish: Clear Zinc.
- Performance: Prevailing-torque compliant with ISO 2320 (re-use cycles).
- Compliance: RoHS conformant.
- Note: U.S. Grade 8 nut strength is similar to metric Class 10.
