ASTM F467 Titanium Fasteners Supplier | Gr2/Gr5/Gr7 Nuts + F468 Bolt Pairing, EN 10204 3.1

Meta Description: ASTM F467 Titanium Fasteners supplier — hex/hex jam/dome nuts in Gr2 (R50400), Gr5 (R56400/TC4), Gr7 (Pd), Gr12 per ASTM F467/F467M. Paired with ASTM F468 bolts/studs. Thread gauged, PMI verified, EN 10204 3.1, anti-galling note included.

F467 vs F468 — Read This Before the PO

A nut-only PO must call out F467; a bolt-only or full-set PO calls out F468 for the male member. Writing "F467 bolt" or "F468 nut" is a standards mismatch that a good inspector will reject — we flag it in the first reply.

Nut Types in Scope (F467)

• Hex nut (standard height, DIN934 / ISO4032 / B18.2.2)
• Hex jam nut (thin, double-nut lock arrangement)
• Dome / cap nut (closed end, dress/cover use)
• Slotted nut on request (castellated, cotter-pinned)
• Left-hand thread on PO

Grade Selection for Nuts

Grade of nut and bolt must be compatible — see pairing rule below.

Bolt + Nut Pairing (how a set is specified)

• Same-grade pairs (Gr2+Gr2, Gr5+Gr5, Gr7+Gr7) = standard
• Gr5 bolt + Gr2 nut: discouraged for high preload — hardness/strength mismatch risks nut thread strip and galling
• Gr7/Gr12 nuts under reducing-acid duty paired with matching F468 bolt
• Washer: flat (ISO7089/DIN125) + spring (DIN127) kitted per assembly
• Set bagged: "M12×1.75 / F468 Gr5 bolt + F467 Gr5 nut / heat No."

Stock Logic (honest)

• Confirmed-heat bar stock on hand; CNC thread + anneal + clean
• Common nuts M6/M8/M10/M12/M16/M20/M24 rotate; window quoted after heat confirm
• Custom pitch (fine thread, left-hand, non-standard width) → short production run, schedule quoted
• MOQ: 100 pcs/size for stock thread; kit bags from 50 sets

Thread & Tolerance

• Metric: ISO 6H nut / 6g bolt; coarse & fine pitch
• Inch: UNC / UNF per ASME B1.1
• GO/NO-GO gauged 100% — reject rings replaced on schedule
• Right-hand standard; LH on request
• Rolled threads preferred (grain flow → fatigue + less galling)

QC Before Pack

1. Heat No. carried bar → bag label
2. PMI/XRF grade verify (R56400 / R52400 / R50400)
3. GO/NO-GO thread gauge per piece
4. 100% visual, burr-free, pickled/clean, ferroxyl iron-check on request
5. EN 10204 3.1: chemistry + tensile from bar heat, QA-signed
6. 3.2 (SGS/BV/TÜV) PO-fronted

Anti-Galling — Written on Every Pack

• Clean mating threads + approved anti-seize (MoS₂ / PTFE / dry film); never assemble dry
• Matched nut/bolt from same heat lot where possible
• Torque from validated preload, not steel tables; re-check 24h after PTFE lube
• Galvanic: insulate from CS/SS with PTFE sleeve in electrolyte

FAQ — ASTM F467 Titanium Fasteners

Q1: Is F467 for nuts and F468 for bolts?
A: Yes. F467 = titanium nut standard; F468 = titanium bolt/screw/stud standard. A correct PO names both when ordering a set.

Q2: Can F467 Gr5 nut pair with any bolt?
A: Pair with F468 Gr5 bolt for high preload. Gr5 bolt + Gr2 nut is a galling/hardness mismatch risk.

Q3: Gr2 nut enough for seawater?
A: Yes — F467 Gr2 is the default seawater/chlor-alkali nut. Gr7 only when reducing-acid excursion rules the joint.

Q4: Thread standard on PO?
A: Mandatory: metric coarse/fine (6H/6g) or UNC/UNF. M10×1.5 ≠ 3/8"-16.

Q5: Rolled or cut thread?
A: Rolled preferred for fatigue and galling resistance; cut thread on request.

Q6: MTC on a nut bag?
A: Heat-linked 3.1 per lot; bag tag carries heat No. No cert downgrade on small qty.

Q7: STA (solution treat + age)?
A: Not default on nuts/bolts; only on PO with heat-treat record and WPS note.

Q8: 3.2 possible?
A: TPI at PO stage; witnesses test + gauge. Cannot be back-built from 3.1.

Q9: Anodize colour coding?
A: Yes (blue/gold/purple) for ID only — cosmetic, not corrosion upgrade.

Q10: HS code?
A: WCO 6-digit 8108.90 base for Ti articles; fastener sub-heading via broker. Process stated on CI.
