Taper Washers
Taper Washers are angled washers designed to compensate for non-parallel surfaces, ensuring even load distribution and secure bolted connections. These washers are commonly used in structural steel applications, railways, bridge construction, and heavy machinery, where beams or fasteners are mounted at an angle.
At Rajal Industries, we manufacture precision-engineered Taper Washers conforming to DIN and general industry standards, ensuring high-load capacity, corrosion resistance, and secure fastening in angled or irregular surfaces.
Sizes & Standards
| Size Range | Standards |
|---|---|
| Varies by angle & application | DIN 434 – German standard for rectangular taper washers for I-beams |
| DIN 435 – German standard for square taper washers for channels | |
| General washer standards – Used across steel structures and heavy industries |
Material & Strength Grades
| Material Type | Available Strength Grades | Industry Standards |

| Stainless Steel (Corrosion Resistant) | A2-70 (SS 304), A4-80 (SS 316) | ISO 3506, DIN 6797 |
| Alloy Steel (High Load-Bearing Capacity) | Class 10.9, 12.9 | ISO 7091, DIN 6797 |
| Phosphor Bronze & Brass (Non-Corrosive & Electrical Applications) | Custom Hardness Ratings | ISO 7091, ASME B18.21.1 |
- Heat-Treated for Maximum Hardness & Load Distribution –Taper washers undergo hardening and tempering for enhanced durability and performance.
- Load Ratings Based on Material & Application:
- Carbon Steel Class 8.8 Taper Washer: 800-900 MPa tensile strength
- Stainless Steel A4-80 Taper Washer: 700-800 MPa corrosion-resistant strength
Taper Washer Design & Engineering Features
Angled Design for Structural Stability & Secure Fastening
- Corrects misalignment when bolting to angled surfaces or non-parallel beams.
Ensures uniform load distribution, reducing stress concentration on fasteners.
Improves Bolt Seating & Structural Integrity
- Enhances bolt performance and prevents slippage in high-load structural applications.
Used for I-beams, steel channels, and railway track fastenings.
Available in Rectangular & Square Shapes for Different Applications
- DIN 434 Rectangular Taper Washers – Designed for I-beam structural fastening.
DIN 435 Square Taper Washers – Suitable for steel channel applications.
Corrosion-Resistant Coatings for Outdoor & Harsh Environments
- Available in hot-dip galvanized, zinc-plated, and stainless steel finishes.
- Ensures long-term durability in construction, marine, and industrial settings.
Heavy-Duty Variants for Load-Bearing Applications
- Designed for high-stress environments such as bridges, towers, and steel structures.
Compatible with structural bolts, HSFG bolts, and foundation anchor bolts.
Thread Specifications & Precision Engineering
| Feature | Description | Application |
|---|---|---|
| Rectangular Taper Washers (DIN 434) | Designed for I-beams & structural steel joints | Bridges, construction, railway fastening |
| Square Taper Washers (DIN 435) | Ensures secure bolting in steel channels & supports | Heavy-duty machinery, towers |
| Hardened Steel Star Washers | Provides high-strength load-bearing capacity | Rail tracks, steel frameworks |
