machine screws

Anthony Thompson <thompson@...>
Was in a hobby shop the other day and saw one of those racks with cute little bags of machine screws, costing several bucks for 8 screws (I won't mention the name of the packager, but many will know who I mean). It reminded me that you can buy them at $2.50 for 100 screws, in all the right model railroad sizes and lengths, from Micro Fasteners (www.microfasteners.com). I have no affiliation with or stake in them, I just buy from them on-line. I'm all for supporting the LHS, but not to this extent.

Tony.
I purchase mine through Fastenal. I ,too, have no ties with them, just down the street.

A few yars ago I bought a small can of 1000 brass 2-56 x 1/4 round head screws, which I hope to run out of in my lifetime.

I second, MicroFasteners is an excellent vendor.

Another great source for a million supplies is McMaster-Carr industrial supply. www.mcmaster.com Drill bits, spring wire, adhesives, fasteners, you name it, most in small quantities, sold to anyone, no minimum, reasonable priceswith outstanding customer service. Need a .005" end mill? It ships today! I have been a loyal customer for business and personal needs for 30 years. My LHS is 120 miles away.

They're cheaper online to be sure, but I just saw $9.70 for 100 1/4" O-80 screws which is 400% higher than what you posted. Perhaps you haven't needed to buy any screws for a while? :-) Tim O'Connor ----- Original Message -----

The 100 0-80 screws you describe, 1/4" long in brass (usually the most expensive material) are $5.10. Don't know where your &9.70 comes from. Of course there is a shipping charge, which I didn't cite because it is highly non-linear with order size, just as I didn't mention tax for a LHS purchase (or your gas to get there and back). But I note you don't contest my contrast between the little bags of 8 screws, vs. a bulk purchase.

Stainless steel. I avoid brass screws -- too soft.

There's this little tool called a tap, which makes threads in the target object to make installation of the screws easier. I suggest you get and use one.

I don't like brass screws as their being non-magnetic can not be held on end of driver while installing and heads are soft allowing them to be easily deformed with screw driver even in threaded hole especially when they have been painted.

I use the blackened ones and silver from NWSL which are magnetic I was not aware of stainless not being magnetic these must be plated.

The 400 series stainless steels are magnetic while the 300 series are not.

Fasteners are rarely made of 400 series stainless, unless they need to be heat-treated for hardness.

However, 316, 18-8, and other "nonmagnetic" alloys commonly used for machine screws can become mildly magnetic when cold-worked, as in the thread-rolling process. Peace, Rick Aylsworth --- In STMFC@..., Todd Horton <toddchorton@...> wrote:

Gosh Tony, you'd be surprised to find 316 stainless steel slightly magnetic?

I am speaking as a former machine designer, welder, and machinist, with experience not only making things out of 302,304,316,440C, etc, but also designing and building machines that cut and shape stainless steel parts for food-processing equipment. Ask any machinist who has cleaned the "non-magnetic" 316 stainless steel chips off his magnetic indicator stand if the stuff is ever magnetic. Or consult an appropriate textbook or handbook. Academics and engineers are often surprised by what happens out in the real world. Peace,Rick Aylsworth

The 300 series stainless steel are generally considered non magnetic. I know there is a small amount of magnetism in them but it's very little compared to regular ferrous steel. I wouldn't try to surface grind a piece of 300 series stainless. The results wouldn't be pretty but I have seen it "attempted" :-)
