Detail

What the drawing controls.

Cold-headed from boron steel wire, roll-formed thread (6g) and continuously quenched and tempered to class 8.8. Head marking is stamped with the property class and our mill code so a lot can be traced back to the heat number on the mill certificate. Supplied zinc plated as standard; hot-dip galvanized to EN ISO 10684 and zinc flake are quoted per order.

Typical applications

Structural steel connections
Machine frames and guards
Pump and valve assembly

Before the PO

What to specify when you order this part.

Send these six lines with the enquiry and the first reply is a price, not a question.

Standard or drawing — DIN 933, ISO 4032, ASTM A193 B7 — or a dimensioned PDF/STEP.
Size and length — Thread size, length, and the length convention the drawing uses.
Property class — 4.8, 8.8, 10.9, 12.9, A2-70, A4-80 — and the joint’s preload, if it has one.
Finish — Zinc trivalent, hot-dip galvanized, zinc flake, black oxide, plain.
Quantity — Per size, per shipment, and annual volume if you have it.
Destination — Port or city and the Incoterm, so freight is in the first number.

ISO 898-1 / -2	Tensile, proof load and hardness results for the production lot.
Coating report	Thickness readings per plating batch, with the salt-spray coupon reference.
FAI / PPAP 3	Ballooned drawing and full dimensional report. On request, before the run.

Before you order

Questions the sales desk actually gets.

Anything else, email sales@ianzai.com — a person answers, usually inside a shift.

What is the minimum order quantity for this part?

This SKU starts at 5,000 pcs and steps in multiples of 500. The stepper will not accept a smaller quantity, and the quote desk will not quietly re-quote one.

Can I get samples before ordering?

Up to five pieces from current stock are free; you cover the courier. For a production-representative sample from a new die, allow 5 – 8 working days and a tooling charge that is credited against the first order.

Which documents ship with the lot?

EN 10204 3.1 for the heat, an ISO 898 test report for the lot, and coating thickness with the salt-spray coupon. FAI and PPAP level 3 are quoted separately because they are built per part number.

Which Incoterms do you quote?

FOB Ningbo or Shanghai as standard, CIF to your port on request, and DDP where we have a cleared forwarder. The RFQ form asks for your port so the first quote already includes freight.

How is the unit price calculated?

From the break at or below your quantity — not an average. Quantities between breaks pay the lower break’s price, which is why the line total is recalculated on the server when you submit.

Can you make a non-standard length or thread?

Yes. Send the drawing, or the standard plus the deviation. Tooling is quoted separately, and we will say plainly if the tolerance is outside what cold heading can hold.
