Waspaloy Fasteners Catalog: Hex Bolts, Studs, Nuts, Washers, 12‑Point & Custom Dimensions

When your application demands strength and creep resistance at temperatures that soften Inconel 718, Waspaloy fasteners become the definitive choice. RAYCHIN LIMITED, a specialist global manufacturer of high‑temperature nickel‑alloy fasteners, offers the complete spectrum of Waspaloy product forms—from hex bolts and socket head cap screws to 12‑point bolts and custom‑machined parts. All are manufactured with in‑house vacuum heat treatment, precision thread rolling, and full AMS 5708 certification. This guide outlines our full manufacturing scope and dimensional capabilities, enabling you to specify with precision.

1. Waspaloy Fastener Product Range

2. Waspaloy Bolts: Metric vs Imperial Dimensional Coverage

RAYCHIN maintains stock, tooling, and inspection gauges for both measurement systems. The table below summarizes our standard size ranges and applicable specifications.

If your design requires a non‑standard thread or dimensional standard—such as JIS, BS, or a proprietary OEM specification—our engineering team can accommodate it. Provide the standard designation and required dimensions with your RFQ.

3. Custom Waspaloy Fastener Dimensions

Beyond the catalog, RAYCHIN specializes in manufacturing Waspaloy fasteners to custom dimensions. Our application engineers work directly with your design team to produce:

• Stepped and multi‑diameter studs for differential thermal expansion compensation.
• Flanged hex bolts with integrated washer faces and specified under‑head fillet radii.
• Body‑bound bolts with precision shank tolerances (h7 or tighter) for shear‑loaded aerospace joints.
• Special head geometries—oval, flat, button, or fully proprietary shapes for unique installation envelopes.

We accept CAD files in STEP, IGES, DXF, and all common formats, and can proceed from a single prototype to full production volumes with identical certified quality.

4. Quality Assurance and Certification

Every Waspaloy fastener shipment from RAYCHIN LIMITED includes:

• Material certification to AMS 5708, AMS 5706, or customer‑specified standard.
• EN 10204 Type 3.1 certificate (Type 3.2 with independent third‑party witness on request).
• Positive Material Identification (PMI) report on finished fasteners.
• Mechanical test report: tensile, yield, elongation, reduction of area, and hardness.
• Heat treatment batch records with full furnace charts for solution annealing, stabilization, and aging.
• NDT reports (FPI or MPI) for aerospace orders.
• AS9102 First Article Inspection Report (FAIR) on request.
