Auto-Lok Slotted Ring Nuts — Horizontal Flange (ALNhsrf)
Class 8 all-metal self-locking nuts with a horizontal slot and flange for easy seating and reliable, repeatable retention. Zinc-clear (Cr3) trivalent finish for clean appearance and protection.
- Material grade: Carbon steel Class 8 (ISO 898-2).
- Thread series: Metric (coarse as listed; fine pitch where noted: e.g., M10/M12/M14/M16/M18).
- Finish: Zinc and Clear (Cr3) trivalent.
- Performance: Prevailing torque type per ISO 2320 (all-metal, no polymer insert).
- Quality system: Manufactured under ISO 9001:2015.
- Application notes: Lower installation torque than many lock-nut styles with stable re-use characteristics; flange helps distribute load on panels and covers.
