What is ASTM F467 / F467M?

ASTM F467 / F467M is the Standard Specification for Nonferrous Nuts for General Use. It covers the nut side of nonferrous fastener assemblies in copper, brass, bronze, monel, inconel, hastelloy, aluminum, and titanium grades. The companion specification ASTM F468 / F468M covers the bolt / hex cap screw / stud side - use F467 nuts with F468 bolts in matched UNS grades.

What nonferrous alloy families does F467 cover?

ASTM F467 covers eight alloy families: copper (C-series like C11000 ETP), brass (C26000 cartridge, C46400 naval), bronze (C51000 phosphor, C61300/C63000 aluminum, C65500 silicon, C67500 manganese), cupro-nickel (C71500 70/30), nickel-base alloys (N04400 Monel 400, N05500 Monel K-500, N06625 Inconel 625, N10276 Hastelloy C-276), aluminum (A92024, A96061, A97075), and titanium (R50400 Gr 2, R56400 Gr 5, R52400 Gr 7, R56401 Gr 23 ELI).

What is the companion standard to F467?

ASTM F468 / F468M is the direct companion specification, covering nonferrous bolts, hex cap screws, and studs in the same UNS grade families as F467 nuts. F467 + F468 together define complete nonferrous fastener assemblies in matched grades. ASTM F436 / F436M covers hardened steel washers when ferrous washers are used; non-ferrous washers are typically specified in the same UNS as the bolt and nut.

Which F467 grades are NACE MR0175 acceptable for sour service?

Most F467 nickel and titanium grades are NACE MR0175 / ISO 15156-listed for downhole and surface nut applications in H2S sour service: Monel 400 (N04400), Monel K-500 (N05500) conditional, Inconel 625 (N06625), Hastelloy B-2 (N10001), Hastelloy C-276 (N10276), Alloy 59 (N06059), Alloy 686 (N06686), and titanium grades (R50400, R52400, R56400, R56401). Aluminum bronzes are generally not preferred for sour-service nut applications; consult NACE MR0175 directly for the current acceptance matrix.

Where are F467 nonferrous nuts typically used?

Marine shipboard hardware (naval brass, aluminum bronze, cupro-nickel nuts), oil and gas wellhead + downhole nut applications (Monel, Inconel, titanium for sour service), chemical-process equipment (Hastelloy, Inconel for corrosive media), desalination + condenser nut bolting (cupro-nickel + nickel-aluminum bronze), aerospace structural fasteners (aluminum 2024 + 7075, titanium 5 + 23), and food + pharmaceutical equipment (titanium + Hastelloy for sanitary chemistry).

What dimensional standards does F467 reference?

F467 nuts are manufactured to ASME B18.2.2 (hex nuts, heavy hex nuts, square nuts, lock nuts - inch series), ASME B18.2.4.1M (metric hex nuts style 1), ASME B18.2.4.6M (metric heavy hex nuts), ISO 4032 (metric hexagon nuts), ISO 4033 (metric hexagon high nuts), ISO 4035 (metric hexagon thin nuts), and DIN 934 / DIN 439 (metric hex nut equivalents). The companion F468 bolt spec references the corresponding ASME B16, B18.2.1, B18.3, B18.6.7M, B18.31 dimensional standards.

How does F467 compare to F468 for matched assemblies?

F468 covers the bolt / hex cap screw / stud side; F467 covers the nut side. Both reference the same UNS chemistry tables - so a Monel 400 (N04400) bolt per F468 mates correctly with a Monel 400 nut per F467. For complete galvanic compatibility, the washer should also be the same UNS (or a deliberately-matched compatible alloy). TorqBolt supplies matched F468 + F467 assemblies on order.

What is the heat treatment for age-hardenable F467 grades?

Age-hardenable F467 grades (Monel K-500 N05500, aluminum 2024 / 6061 / 7075) require specific solution + age cycles defined in the standard. Monel K-500: solution 1600 F + age 1080 F / 8 h + 900 F / 8 h. Aluminum 2024-T4: natural age 96+ hours at room temperature. Aluminum 6061-T6: artificial age 350 F / 8 h. Aluminum 7075-T6: artificial age 250 F / 24 h. All TorqBolt heat-treat is fully documented with traceability to F467.

Residual elements need not be reported unless a report is specifically required by the purchaser. (C) Ruthenium and Palladium, or both, may be added to Grade 19 for enhanced corrosion resistance as negotiated between purchaser and vendor. Chemical analysis is not required unless specifically negotiated.

ASTM F467/F467M Supplementary Requirements

S1 – Stress Corrosion Requirements, Copper Alloys

The S1 supplementary requirement focuses on stress corrosion resistance testing for copper alloy fasteners used in corrosive or high-moisture environments. This testing helps identify susceptibility to cracking caused by combined tensile stress and chemical exposure. It is especially important for marine, chemical processing, and offshore applications where corrosion-related failures can occur. Compliance with S1 improves long-term durability, structural reliability, and service safety of the material.

S2 – Shipment Lot Testing

The S2 supplementary requirement specifies additional shipment lot testing to verify that each production batch meets the required mechanical and chemical properties. This testing ensures consistency in material quality, dimensional accuracy, and performance before delivery to the customer. It provides enhanced traceability and quality assurance for critical engineering applications. Shipment lot testing helps reduce the risk of defective or non-conforming fasteners entering service.

S3 – Dye Penetrant Inspection

The S3 supplementary requirement requires dye penetrant inspection to detect surface cracks, discontinuities, or defects that may not be visible during normal visual examination. A penetrant liquid is applied to the material surface to reveal fine imperfections after processing. This non-destructive testing method improves quality control and helps prevent premature component failure. It is commonly used for safety-critical fasteners and precision-engineered assemblies.

S4 – Heat Control (Alloys 400, 405, and 500 Only)

The S4 supplementary requirement applies specifically to Alloys 400, 405, and 500 and establishes stricter heat control procedures during manufacturing. Proper heat identification and processing ensure the material maintains the required mechanical strength, corrosion resistance, and metallurgical consistency. This requirement also supports traceability of production heats for quality verification and certification purposes. Heat control is essential for maintaining reliable performance in demanding industrial environments.
