    Hi Guys does anyone have a source for the the common sizes of the machine screws with captive spikey washer in bulk? As used on mechs etc, I want to be able to buy some in bulk like a few hundred at a time. Not having much luck
    Cheers

    I don't buy them by the hundred but when I do buy, I buy them from Marco.

    Those are called "Sems" screws. Here is where I buy them dirt cheap:

    https://www.boltmax.com/products.php?cat=523

    Those prices are for a bag of 100 screws. Example: 4-40 x 1/4" long are just $1.84 for a bag of 100.

    I believe there is a typo error on the price of 6-32 x 1/2" long ones. No way should it be $25.24 for a bag of 100. I think it is supposed to be $2.52. Someone should call that to their attention.

    My buddy Welby Bergum usually buys 5 bags of 100 for each size we usually use. Sure makes things pop with shiny new screws installed. Coin doors use lots of 6-32 x 1/4" and 8-32 x 1/4" SEMS screws.

    True, I use them at work a lot, saves me a LOT of time, & the less time spent looking for stuff saves $$
