Large Wood Screws from Schaff

[Terry Farrell]

Andrew sent me my large wood screws. Some had asked how they looked - sharp threads, etc. I’m no expert on metal machining, but they look pretty good to me. Judge for yourself:

Hmm? You can't see he difference? The Zinc plated ones have blunt edges on the cut threads. The surface is mottled making insertion more difficult.
Good picture for comparing the plain steel to the zinc.
 I suspect they'll be somewhat adequate. Since the sources are really difficult to find, it's better than nothing at all.

Not so much.

The Zinc plated ones have blunt edges on the cut threads.

It appears the rounded threads are more pronounced in the picture. Holding them up in front of my nose, they really look pretty similar. I was wondering whether the plating might make the thread edges a bit rounded.

The surface is mottled making insertion more difficult. 

The area between the threads? How would that make insertion more difficult?

Good picture for comparing the plain steel to the zinc.

Thanks.

I suspect that also.

Absolutely.

As much as I appreciate the nice sharp machining of the steel screw,
I've put in a whole lot of zinc plated ones like the one shown, and
worse. They work fine, realistically, if you are interested in function
over cosmetics. Is the head clean, or gobbed up like the ones I've
gotten from Schaff? That is a cosmetic concern I can support.

Ron,
Please define "gobbed up".

Not smooth, not flat.

My guess is that it would qualify as  “gobbed up”. Looks about the same as the originals though. Perhaps screws with other plating are smoother, I don’t know. These will be fine for my use on my customer’s legs. I mean her piano’s legs.

That glop in the center is what I was talking about. The screws I got
were much worse than that, extending over half of the head. I've gotten
a lot of zinc plated screws from hardware stores through the years that
were far nicer looking, when they went into something that didn't matter
at all (like legs). But screws going into my nice refinished plate
looked like crap.

Ah! Gotcha! New nomenclature added to my list.<G>
