Slotted Ring Nuts — Vertical
All-metal slotted ring lock nuts designed for vertical installations where space is tight but reliable prevailing-torque locking is required. Lower tightening torque than traditional lock nuts and excellent vibration resistance.
How it locks: Elastic deformation of the slotted ring generates a consistent interference fit on the screw threads.
Where it shines: Vertical stacks, blind assemblies, and restricted envelopes.
Performance: Stable prevailing torque across multiple re-use cycles (per ISO 2320 practices).
Value: Slim profile with secure locking action—ideal for cost-sensitive builds that still need reliability.
- Compact form factor for space-constrained assemblies
- Lower installation torque than many alternative lock nuts
- Excellent resistance to vibration-induced loosening
- All-metal design—temperature and chemical tolerant
- Available across common property classes and stainless grades

Installation note
Use tightening torque from your engineering standard and verify prevailing-torque windows per ISO 2320 across re-use cycles. Lubrication, coating, and class will influence torque values.
