As a pro remodeling contractor I go through a fair amount of drywall screws.
Mostly 1.25" black course thread. These screws used to be fairly "dry" but
for about the past five years or so I have had a real hard time finding
screws that are not covered with oil. This oil is stinky greasy petrol
smelling stuff that makes the screws unpleasant to handle. Gets all over my
fingers, it's probably toxic, and could keep the mud from sticking to the
screw heads? This problem is not just with the off brand / Borg screws. The
last box i bought were "Grabber" brand screws... same problem. So there is an
800 # on the box which i called and had a long convo with a guy at Grabber.
He said there "shouldn't" be much oil on the screws and yes it could cause
problems with the mud sticking. One of the things he suggested is to try the
gold screws instead of the black screws. In my 25 years of construction work
every drywall job i've ever been around it seemed to be standard practice to
use the black screws so this is what I've always done.
Is there any reason not to use the gold screws for drywall?
I'll submit that the cost of fasteners for a project gets lost in the
My guess is that a 5% savings on the cost of basic materials more than
cover the cost of fasteners for the project.
There was a time I worked in the fastener capital of the USA,
SFWIW, most of my fastener manufacturing customers had closed up shop
and moved off shore by the mid 1980's.
One of the many jobs I have had, was in a machine shop making screws and
the problem with the ones you have may be in the final washing where the
screws are washed in a solution, to get rid of any residue
I can't foresee any problems with an oily residue on the screws to inhibit
I don't know about drywall but I have had a few oily screws that stained the
Enough oil will bleed through cover mud compound, and make it impossible for
latex paint to cover the bleeding oil. You would have to use oil kilz stain
block before finishing the wall.
The obvious solution is to wash the screws if you have them already, and
Otherwise, let your wallet dictate the quality of the supplier. Don't buy
them until the oil problem is solved.
Damn made in China syndrome. It gets worse all the time.

Yes! I'm finding that even with the "quality" hardware suppliers the stuff is
all coming from China or Taiwan. I cant find the standard black drywall
screws in bulk from *anyone* that are not all friggen greasy. The gold screws
are about the same price and seem much dryer.

I agree that for the mechanical fastening of the drywall panels to the
framing the oil does not inhibit their performance in any way. If however
you include user friendliness as part of a product's performance then the oil
is a pretty serious flaw. Also in drywall work it is very important that the
mud adhere tightly to the screw heads so could also be another flaw there.
Personally I think I'd want to find out whether the oil is normal or
not. Have you thought about sending a box of oily screws to the
manufacturer and asking if the oil on them was normal? If it isn't then
it's getting on them in transit somewhere and I suspect they'd be happy
to help you find out where and apply some pressure from above to get the
Isnt it to prevent rusting of the tin once pierced by the screw ,
causing the screw to loose grip .
Probably not such an issue in the USA (oh by the way thanks for
wacking bin laden) but in many countries it is , in production its
unlikely they will know the intended market so they all get done.
Plus these are generally shipped by sea so it possibly prevents
