Thread: Black Screws

Spray the heads with black enamel paint and bake them in the oven at about 170C for about 10 min. Allow to cool in the oven.

Then try to get the smell out of the oven over the next month

You can use brass screws and blacken them with "barrel blue" available from any gunsmith and a bunch of other places.

would this work with galv coach bolts?

It does but sanding, priming and spraying will work fine too.

Dunno about gal coach screws, never done them. Can't see any reason why not though as long as they are cleaned properly before spraying them. Roof and cladding screws are gal coated and are available in a range of colour band match colours. Try and find out I suppose.

I don't have a missus to bitch about what I do in my kitchen, but I do have a small toaster oven type thing I use for stuff like that. After i'm done and the painted stuff has been removed I usually turn it back on and crank it up for ten minutes then open the door and let it cool.

I got some black screws from bunnings a while back

Instead of using the kitchen oven, hang small stuff next to a old incandescent lamp.
For bigger stuff I use an old mains gas powered BBQ just on low for about half an hour.
That old BBQ gets used for lots of things like melting lead and softening/forming plastics.
Here's a 100mm diameter HDPE cylinder made out of plastic milk bottles

They have them in white too.

Thanks to everyone for your tips. My wife was horrified about her oven being used to bake screws! Noted about the used of an old incandescent lamp by BobL.

Going though to Bunnings to look at the screws there as 25mm is a good length for me.

Oh only 25mm? If you're happy with star head, you can get automotive screws from any car parts store as well.

Bloody hell Bob! Hope you're staying well away from that BBQ when you're melting lead, it's evil stuff.

Thanks for the tip Steve.

I spent some time researching environmental lead at work so have a pretty good idea of what's involved.
No I'm not hanging around while it melts but there is something worth knowing about safely melting lead.

It melts at 327ºC, and it has to be heated to 705ºC to get the vapour pressure to just 1Pa (1/100,000 of an atmosphere).
Even though that is quite a low pressure it will be above the 0.5 ppb recommended safe limit for lead in air.
However this assumes you are going to stick your face close to the surface and keep it there will you breathe in the lead vapour.
Also to get lead to 705ºC using a BBQ requires the flame to be in contact with the lead itself so if you avoid that its a much safer process.
I generally melt lead in a steel container outside, at well below 705 (about 450ºC) - you can do it at a lower temp but it takes longer.

So why don't you by whatever screws suit and take them back to the blacksmith and get him to treat them in whatever manner he did the hardware?
