The coatings that i am referring to are not hot dip galvanized. Geomet, Magni, and Delta MKS are some of the names that I am familiar with. I think that some might have a topcoat that contains teflon for reducing the coefficient of friction, but I do not think that all have Teflon added. If they...
Are anerobic thread locking compounds effective when used with fasteners that have dip-spin or spray applied zinc-flake coatings for corrosion resistance?
Can anyone explain to me what the differences are between standard metric grade 10.9 bolts and bolts marked as "10.9 HV"? I found the EN 14399 standard that seems to suggest that these fasteners are designed for "preloaded joints", but that makes no sense to me because all bolted joints are...
Does anyone know where (or if) I can find salt spray test data that compares,side-by-side in the same test, the corrosion resistance of zinc/aluminum flake coating systems from the various manufacturers like Doerken Delta MKS, Magni, Geomet,Sermagard, Whitford, Zintek, Empigard, etc?
Does anyone out there know if there is any difference in the clamp load generated in a joint using a stud and nut, versus the same joint using a capscrew?
does anyone know where i can find a ranking of the costs of the non- hexavalent chrome coatings that are used for fasteners. I found this very helpful posting with a table of the coatings ranked by corrosion resistance, but not cost. thread332-189454. can I assume that the least effective are...
