No longer used in Blacet products... 4-40 x 3/8" Philips pan head machine screw stainless steel: for some reason have 4196. 1K pcs for $20 + $5 US shipping. Also have somewhat smaller quantities of same type screw in 8-32 x 1.5, 8-32 x 1.25, 4-40 x 3/8" flat head. email for a quote. These are going to ebay soon but thought I'd run them by DIY first. John
