This item came from a computer accessory company that is no longer with us, called Mad Dog Multimedia. Pictured is the contents of one bag of anodized aluminum computer case thumb screws, with 4 pcs each of blue, black, and bright silver screws.  The sale is for 5 complete unopened bags, or 60 screws in total.  Each screw is approximately 1/2" wide where they are knurled, and there are just under a quarter inch of 6-32 threads under the shoulders.  Total height, or projection from a case, is about .41".  For some reason, there is a slight variation in the blue anodizing from piece to piece, and bag to bag.  So there are two very slightly different hues of blue, but unless two were side by side, most people wouldn't notice.  I also have these listed in a slightly smaller quantity (3 bags).   I guarantee to ship the item shown and that it will match the description, but nothing beyond that.  They are sold "as-is" with no return. Ships standard mail anywhere within the U.S. for FREE.  Not free to ship out of the U.S.,  an additional $12 over the selling price.  Feel free to ask questions or for other photo views.  In addition to Paypal I accept personal and business checks.  Please wait for my confirming email prior to payment.  No reserve.
