Metal Washers

How about fender washers? Available at Lowe's, among other places.

I seriously doubt that you'd find 1/4" to 3/8" thick fender washers at Lowe's, or stock washers that large with a hole as small as 3/8" anywhere.

For that small quantity you could buy a strip of steel stock, saw it into squares and drill 'em faster and cheaper than you could find someone to make them for you. "Cold Galvanizing" paint or a DIY home zinc plating kit could give you pretty fair rust protection if that's needed.

Good luck,

McMaster-Carr -- search for "structural washers" or catalog number 91128A115.

Jeff is right. I just picked up some "plate washers" at Tacoma Screw Products that are about as thick and large as you can get off the shelf. 3" O.D., .2" thick for a 3/4" bore. And note that the bore is REALLY sloppy and actually about .85". I doubt you will find what you want for that 3/8" bore.

Cut some bar stock and drill it and you will probably get be closer to the sizes you want rather than scabbing together what you can get off the shelf.

I guess Ned Simmons just taught both of us not to be so skeptical about what's available somewhere in this big wide world, huh? (My face is RED.)

But at $30 for 18 of 'em in black oxide, plus shipping and waiting, I'd still suggest the DIY version if he has the tools to do that little bit of work.

Yup....opened mouth and inserted foot very deeply this time just because I was all high and mighty and *thought* I knew what I was talking about.

Now if I could just find those round washers with the hole in the plane perpendicular to the standard holes.......Or those bolts that screw both in and out by rotating clockwise.....(hey...Ned found that washers above so ya never know!)

Koz

I've made quite a few of those bolts from standard RH ones over the years. I think they're called "stripped", aren't they?

Jeff

Drill the barstock BEFORE you cut it to length, it's a lot easier to clamp. You might look at the availability of "bridge washers" in 3/8". They are a heavy cast malleable washer.

I got a good supply pieces about this size from a VOR Counterpoise (antenna ground plane) built from hot galvanized steel. Each structural element had a stamped steel tag attached with wire prior to galvanizing. As the structure was erected, these tags were discarded and the resident pack-rat collected them. It is amazing how often a two inch square of 1/4" galvanized steel comes in handy - I'm almost out of them now! Gerry :-)} London, Canada

Thanks Ned, We will get twenty

You could get burnouts from laser shop and drill your holes in,,Thay have lots of scrap that way!!!!!!!!
