Screw Lube?

Post by Mrlew » Mon Sep 02, 2013 3:17 pm

Gotta be careful with that subject :oops:

Didn't know if I should post here or in "Fasteners" but since I'm building a Sissy Do.........

What do you use to lubricate wood screws to make driving easier and stripping less likely? I've heard some folks using common Ivory soap but I've also read that soap is hydroscopic (attracts water) and can cause issues later. I have found that silicon/bronze screws, even with frearson heads, do have a tendency to strip if you've not very careful and figure a little lube could go a long way.

Thanks,

Chris

I believe you can use ski wax or equivalent.

My dad, who was a carpenter by trade, used liquid dishwashing soap. Keep a small cup of it and just dip the screw tip in it.
Also, I was having trouble with the SB screws breaking as I was fitting the planking, etc. So, as suggested somewhere in the forum, I used normal steel screws to fit the panel, and then substituted the SB screws when it was epoxied into place. The steel screws created a preformed hole and allowed the final screw to go in without breaking.

Akempucky works great. Sold by Jamestown Distributors and others I'm sure. Here is a link to Jamestown site.

I looked into Akempucky a while ago, unfortunately it is no longer made. The Jamestown link says "no longer available".

I've heard bees wax is better than soap.

Oh no! And I was about to order more. There is another product called Screwwax sold by Woodcrafters and Amazon. Looks to be the same as Akempucky.

If, they are pre-drilled correctly, you should have little issues. If any further assistance is needed, as mentioned above, a bar of soap is the ticket.

I am with Bill cnc pre drill properly and you do not need to lube. your screw should only be cutting a thread in your timber not forcing
your screw in splitting your timber..

Steel screws run into yellow pine with 'bar soap' lube corroded very badly, very quickly.
I avoid bar soap lube.
Oak is over rated, everything about it takes extra time; then it warps, splits or checks !!! :roll:

Kens, I totally agree. Here is a good primer on wood screws that deals with all of the issues raised in this thread plus some.

Um, ... nobody said bar soap is a preservative for steel. Why anyone would use steel fasteners on a boat is a complete mystery to me. I wouldn't even use stainless fasteners that you cannot easily access for replacement, and yes, that includes construction fasteners buried in glue or under glass, ... but that's just me.
