This Stainless Steel CNC Machined Hex Cap Nut is an Aunov Tech production part in stainless steel, quoted and built to customer print. In the assembly, the CNC machined part delivers the precise turned or milled geometry the assembly mounts to. The same floor forms, machines and inspects the part, which keeps tolerances consistent from sample to volume without re-quoting the job elsewhere.
Product overview
What defines this stainless steel cap is, wall thinning, concentricity and the finished mating faces, audited against the approved sample at each production release.
The whole route from die to finished stainless steel cap stays in house, so revisions do not wait on outside suppliers, with the tooling history retained in house.
How it is manufactured
Production follows a defined route: Machining starts from bar or plate and runs on CNC centres; threads are single-pointed or rolled and seats bored in one setup where possible.
Route cards follow each manifold block batch through the shop, so the next run starts from the data that already worked. That record is what every manifold block reorder is built on, so nothing changes silently between shipments.
Materials and surface finish
Our stock list runs to SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with 304 / 316 stainless steel specified on the drawing for this stainless steel cap.
The surface treatment is picked to match the service conditions: zinc and nickel plating, chrome, anodising, powder coating and passivation. The finish on this stainless steel cap is locked to the drawing revision, so later orders match.
Each manifold block shipment is verified against the master sample before it leaves the shop. Process settings for the manifold block are archived, so later runs can be compared with the one you approved.
Quality control and inspection
Quality management is certified to ISO 9001: incoming material is verified against mill certificates, first articles are measured on a CMM, and run inspections follow an agreed sampling plan. For the manifold block, first articles are CMM measured and threads are gauged to class. Torque, leak and pressure tests are available where the assembly needs them, with certificates included in the shipment file.
Applications
You will find this stainless steel cap inside industrial machinery and equipment assemblies across automotive, appliance and industrial programmes.
One part number for this stainless steel cap frequently serves several assemblies, so one tooling set serves every position, and the drawing stays common.
Options and variations
Options changed most often
Customer choices typically cover material (carbon steel, stainless, aluminum, brass), surface treatment, thread classes, seat finishes, milled features, cross-holes and plating or anodizing to the print, and order shape – prototype lots first, scheduled volumes after approval.
Every change is quoted with its tooling consequence shown, so decisions are easy to make.
Specifications
| Item | Stainless Steel CNC Machined Hex Cap Nut |
|---|---|
| Brand | AUNOV |
| Designing | Quotation follows the print, not a catalogue – samples are reverse-measured into a controlled drawing; the agreed version governs every later batch. |
| Tooling | Progressive and drawing dies are designed and built in house, so a die can be re-cut against the approved drawing, and the die remains dedicated to your part. |
| Samples | First-article samples ship with a dimensional report and material certificate. |
| Materials | Stainless 304 and 316L, pickled and annealed, 0.5-3.0 mm nominal wall – one grade chosen for corrosion duty and formability of this cap. |
| Surface finish | Finish selected from the drawing: plating, coating, anodising or passivation; the agreed finish travels with the part number. |
| Processing | Turn-mill machining, critical diameters finished in one setup; every stage is logged against your part number. |
| Equipment | 12 CNC turning centres with automatic bar feeders, backed by CNC turning centres and a climate-controlled inspection room. |
| Tolerance | +/-0.01 mm on critical bores, confirms at DFM stage; GD&T per drawing, PPAP-style reports on request. |
| Delivery terms | Freight, Incoterm and payment term are confirmed on the order: FOB, CIF or DDP, T/T or L/C. |
Packaging and delivery
For this stainless steel cap, protection starts at the surface: each coating gets its own packing – interleaves, bags or trays, in sealed cartons on export pallets; shipping documents and carton marks follow your instructions.
