ISO10683 flake zinc family

ISO10683 flake zinc family

ISO10683 flake zinc family

Hello all,

I do not have access to this standard. But Zintec, Dacromet, Riwdac, Geomet, Delta-Tone 9000, Delta Protect etc. belongs to the "family" of flake zinc.
Can anyone tell, that if I am ordering Geomet coated screw it has the same properties as screw which is described only as "flZn"?
Or these names are only brands from different manufacturers?

I am a little bit confused because I ordered some Geomet screws, but I received few boxes described as "flZn".
Is it 100% equivalent?

Thanks in advance

RE: ISO10683 flake zinc family

Regarding my sentence: "Or these names are only brands from different manufacturers?"

Not so sure about that because Dacromet has chrome, Geomet does not...

additional explanation:

The goal was to put a coating on 12.9 steel screw. I had some experience with wrong applied flZn on the screw, which "ate" 25% too much of screw's thread height (this was visible under microscope)- as a result threaded aluminium blocks had destroyed thread while applying a torque to this screw.

RE: ISO10683 flake zinc family

There are so many varieties of Geomet coatings, and ISO 10683 has several classifications, so you cannot assume same properties with only flZn designation. There can be substantial differences among Zintec, Geomet, Delta, etc.

When you say you "ordered some Geomet screws", what did you say exactly?

RE: ISO10683 flake zinc family

I meant "screws with Geomet coating"

RE: ISO10683 flake zinc family

I meant did you create a purchase order that stated your requirements explicitly. Something like "coat screws with Geomet 321 + Plus topcoat. Total coating thickness to be 10 micrometers thick."

eBook - Rethink Your PLM
A lot has changed since the 90s. You don't surf the Web using dial-up anymore, so why are you still using a legacy PLM solution that's blocking your ability to innovate? To develop and launch products today, you need a flexible, cloud-based PLM, not a solution that's stuck in the past. Download Now
White Paper - Using Virtualization for IVI and AUTOSAR Consolidation on an ECU
Current approaches used to tackle the complexities of a vehicle’s electrical and electronics (E/E) architecture are both cost prohibitive and lacking in performance. Utilizing virtualization in automotive software architecture provides a better approach. This can be achieved by encapsulating different heterogeneous automotive platforms inside virtual machines running on the same hardware. Download Now
