Detail
What the drawing controls.
Formed from 65Mn strip, quenched and tempered to 42–50 HRC so the washer keeps its spring rate instead of flattening. Ends are ground square to give a defined bearing surface. Zinc plated; hot-dip galvanized available from 3,000 pcs.
Typical applications
- Vibrating machinery
- Piping supports
- Transformer and switchgear 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.
Paperwork
What ships in the carton.
Documents are issued per lot, not per year. The lot number on the label is the key to all of them.
| Document | Covers |
|---|---|
| EN 10204 3.1 | Mill test certificate for the wire rod heat — chemistry and mechanical properties. |
| 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. |
| RoHS · REACH | Declaration of conformity for the coating and material. |
| Packing list | Lot number, carton count, gross and net weight, HS 7318 for the broker. |
Before you order
Questions the sales desk actually gets.
Anything else, email matrixgrowth@foxmail.com — a person answers, usually inside a shift.
What is the minimum order quantity for this part?
This SKU starts at 20,000 pcs and steps in multiples of 2,000. 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.
