Product Detail
Product Introduction
Grade 2 Titanium Fender Washers are flat washers with a relatively large outside diameter compared with the bolt hole. They spread bearing load over a wider area, but plate bending, washer dishing, edge distance, hole clearance and mating-material strength must be checked for the complete joint.
Product Specifications
| Product | Grade 2 Titanium Fender 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
- Bearing area: Choose OD and thickness from the mating material, hole or slot size, edge distance and required bearing stress.
- Hole and fit: Define inside diameter and clearance for the fastener without allowing excessive eccentric loading.
- Stiffness and seating: Confirm washer flatness, thickness and support so the large washer does not dish or bridge an uneven surface.

FAQ
Why use a fender washer instead of a standard flat washer?
Its larger OD distributes bearing load over more area and can bridge an oversized or slotted hole, subject to plate and washer stiffness checks.
Does a larger OD always improve the joint?
No. Insufficient thickness or uneven support can cause dishing or bending, and nearby edges can limit effective bearing area.
What dimensions should be stated?
Provide bolt size or ID, washer OD, thickness, flatness and edge requirements, quantity, mating material, tests and certificates.
