RAYCHIN LIMITED, a specialist global manufacturer and supplier of high-performance nickel alloy fasteners, produces the complete range of Incoloy hex bolts, stud bolts, socket head cap screws, threaded rod, heavy hex nuts, washers, and flanged bolts in all major Incoloy grades—800, 800H, 800HT, 825, 925, 945, and 25-6Mo. This catalog details our product forms, dimensional capabilities, and quality standards, helping you specify the exact fastener your project demands.
1. Incoloy Fastener Product Forms
? Incoloy Hex Bolts
Incoloy hex bolts are manufactured to ASME B18.2.1, DIN 931/933, and ISO 4014. Available in partial and full thread, sizes from 1/4″ to 2″ and M6 to M48. Ideal for furnace flanges, chemical processing equipment, and high-temperature piping where oxidation and corrosion resistance are required.
? Incoloy 825 Stud Bolts & 800 Double End Studs
Incoloy 825 stud bolts and Incoloy 800 double end studs are produced as double-end studs per ASME B16.5, fully threaded studs per DIN 976. Diameters from 1/4″ to 2‑1/2″ and M6 to M64. Lengths up to 3 meters. Rolled threads for enhanced fatigue life and resistance to galling during assembly.
? Incoloy 800H Socket Head Cap Screws
Incoloy 800H socket head cap screws per ASME B18.3 provide compact, high-torque fastening for confined spaces. Sizes from #4 to 1″ and M3 to M24. Common in furnace sensor mounts, linkage pins, and actuator attachments in high-temperature environments.
? Incoloy Threaded Rod
Incoloy threaded rod (continuous-thread studding) is cut to your specified length with chamfered ends. Available in 800, 800H, 825, 925, and 25-6Mo. Diameters from 1/4″ to 2‑1/2″ and M6 to M64. Full lot certification and PMI testing included as standard.
? Incoloy Heavy Hex Nuts
Incoloy heavy hex nuts per ASME B18.2.2 and DIN 934 are proof-load matched to the corresponding bolt or stud. All-metal prevailing-torque lock nuts are also available for vibration-resistant assemblies in chemical and furnace applications.
⬜ Incoloy Washers
Incoloy washers—flat per ASME B18.22.1 / DIN 125 and spring lock per DIN 127—match bolt diameters from 1/4″ to 2″ and M6 to M48. Custom outside diameters and thicknesses are available for specific joint designs.
⚙️ Incoloy 925 Flanged Bolts
Incoloy 925 flanged bolts integrate a washer-like bearing surface under the head, distributing clamp load without a separate washer. RAYCHIN manufactures these to your custom dimensions, with the high strength and NACE-compliant properties of Incoloy 925 for demanding wellhead and subsea applications.
2. Incoloy Fasteners Dimensions: Metric and Imperial
Incoloy metric bolts and imperial sizes are fully covered. RAYCHIN maintains tooling and inventory for both measurement systems. Simply specify the thread standard and dimensions on your RFQ.
3. Custom Incoloy Fastener Manufacturing
Beyond standard catalog items, RAYCHIN specializes in manufacturing custom Incoloy fasteners to your exact specifications. Our CNC machining centers accept CAD files in STEP, IGES, DXF, and PDF formats. We produce flanged bolts, stepped studs, body-bound bolts, and fully custom geometries from prototype quantities to full production runs. Every custom fastener receives the same certified heat treatment, mechanical testing, and final inspection as our standard products.
4. Quality Assurance and Certification
Every Incoloy fastener shipment from RAYCHIN includes:
- Material certification to ASTM B408 (800/800H/800HT), ASTM B425 (825), ASTM B805 (925/945), ASTM B649 (25-6Mo)
- EN 10204 Type 3.1 certificate (Type 3.2 with independent third-party witness on request)
- Positive Material Identification (PMI) report—OES analysis on finished fasteners
- Mechanical test report: tensile, yield, elongation, and hardness
- Heat treatment batch records for solution annealing or age hardening
