Product Detail
Product Introduction
Grade 2 Titanium Split Lock Washers use a helical split ring that deflects as the joint is tightened. Locking performance depends on washer geometry, hardness and spring response, mating surfaces, preload, vibration and reuse. A split washer should not be treated as a universal substitute for a validated joint-locking method.
Product Specifications
| Product | Grade 2 Titanium Split Lock Washers | Material | Titanium Grade 2 / UNS R50400 |
|---|---|---|---|
| Product Form | Flat, split-lock or drawing-specific washer | Typical Inquiry Range | For M2 to M36 fasteners in typical inquiries; custom ID, OD and thickness by review |
| Dimensional References | ISO 7089/7090, DIN 125, ASME B18.21 or approved drawing | Threads / Dimensions | Metric coarse or fine, UNC, UNF or drawing-specific as applicable |
| Surface | Machined and cleaned; lubricant, anti-galling treatment or coating by agreement | Documents | MTC, heat/lot traceability and dimensional inspection report |
| Inspection | Dimensions, thread gauging, surface and agreed functional or mechanical tests | Supply Basis | Approved purchase order, invoked standard and drawing |
Typical inquiry ranges are not a stock guarantee. Final manufacturability, tolerances and test requirements are confirmed against the complete RFQ.
Selection and Configuration
- Ring geometry: Define inside and outside diameter, section width and thickness, free height, split and end form.
- Mating surfaces: Confirm compatibility with the bolt head or nut, bearing surface and any coating or soft material that could be damaged.
- Locking validation: Evaluate preload retention, vibration, temperature and reuse in the actual joint rather than assuming the split ring guarantees locking.

FAQ
Do split lock washers always prevent loosening?
No. Their effectiveness depends on preload, joint stiffness, vibration, mating surfaces and washer spring behavior. The complete joint must be validated.
Can a split lock washer be reused?
Reuse should not be assumed because previous flattening, surface damage and loss of spring response can change performance.
What should an RFQ include?
Provide grade, dimensional standard or drawing, ID, OD, section, free height, quantity, joint materials, vibration duty, tests and certificates.
