17‑4 PH Fasteners Product Range: Hex Bolts, Studs, Nuts, Washers, 12‑Point & Custom Manufacturing

When sourcing 17‑4 PH stainless steel fasteners, engineers and procurement teams need a manufacturer that can supply every product form, every heat treatment condition, and every certification level—from a single, reliable source. RAYCHIN LIMITED is that partner. We produce the complete catalog of 17‑4 PH hex bolts, socket head cap screws, stud bolts, heavy hex nuts, washers, threaded rod, and 12‑point bolts, all with in‑house vacuum aging, rolled threads, and full EN 10204 documentation. This guide outlines our full manufacturing scope, enabling you to specify and order with precision.

1. Comprehensive 17‑4 PH Fastener Forms

We manufacture the following product types in all standard heat treatment conditions—H900, H925, H1025, H1075, H1150, and H1150D—with in‑house vacuum aging and full mechanical property certification.

2. 17‑4 PH Bolts: Metric vs Imperial Coverage

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

If your specification calls for a thread or dimensional standard not listed here—such as JIS, BS, or a company‑specific standard—our engineering team can accommodate it. Simply provide the standard designation and the required dimensions on your RFQ.

3. 17‑4 PH Custom Fasteners: Your Drawing, Our Manufacturing

Beyond the catalog, RAYCHIN excels at producing 17‑4 PH custom fasteners manufactured to your exact dimensions. Our application engineers work directly with your design team to manufacture components that meet your precise requirements:

• Stepped and multi‑diameter studs—single components with different thread sizes and shank diameters.
• Flanged hex bolts—integrated washer faces with specified under‑head fillet radii for fatigue‑critical joints.
• Body‑bound bolts—precision shank diameters with h7 tolerance or tighter for shear‑loaded aerospace connections.
• Special head configurations—oval, flat, button, truss, or proprietary profiles.
• Valve and actuator components—stem extensions, connection pieces, and specialty gland bolts.

We accept CAD files in STEP, IGES, DXF, and all common formats. Manufacturing can proceed from a single prototype to full production volumes, with every component receiving the same certified heat treatment, mechanical testing, and final inspection as our standard fasteners.

4. Quality Assurance and Certification

Every 17‑4 PH fastener shipment from RAYCHIN LIMITED is supported by a complete quality dossier:

• Material certification to ASTM A564 Type 630, AMS 5643, or ASTM F593 as required.
• EN 10204 Type 3.1 material certificate as standard; Type 3.2 with independent third‑party witness inspection on request.
• Positive Material Identification (PMI) report—OES analysis performed on finished fasteners.
• Mechanical properties test report—tensile, yield, elongation, reduction of area, and hardness (100% verification).
• Heat treatment batch records—complete furnace charts for solution annealing and precipitation aging.
• NACE MR0175 compliance statement for H1150D fasteners.
• Optional surface finishes: passivation per AMS 2700, electropolishing, and pre‑applied anti‑seize coatings (MoS₂, boron nitride).
• Aerospace documentation: AS9102 FAIR, NADCAP NDT (FPI/MPI), and full lot traceability.

5. Why RAYCHIN is the Preferred Source for 17‑4 PH Fasteners

• Full manufacturing integration: We do not depend on subcontractors for heat treatment, thread rolling, or testing. This eliminates supply chain gaps and quality escapes.
• All conditions, one source: H900 through H1150D, including double‑aged conditions—all produced with our own calibrated vacuum furnaces.
• Fast response on custom parts: Our CNC machining and turning centers are equipped for rapid prototyping and production, with engineering support for your design optimization.
• Global delivery: We ship to OEMs, service bases, and project sites worldwide, with expertise in complex export documentation.
