1772UD3E.1.34New #12 x 1-1/4" Self Drilling Screws with Bonded EPDM Rubber and Steel Washers, Part Number C30193-100. Each bid quantity is for a sealed factory bag of One Hundred (100) Pieces. You may bid / buy any number of lots, up to the total quantity available above.
This item was acquired at an industrial sale recently, and they are brand new in the original factory bags. These are truly the "Rolls Royce" of screws, and they are very expensive at hardware and building supply stores.
These are made from hardened steel with a zinc coating to help prevent rust. The tough EPDM rubber washers are securely bonded to the steel backup washer, so they stay put when you draw them down tight. Cheaper screws have rubber washers that are simply put on the screw shank loose, and they often spin/squirt out from underneath the head.
