6MM

2856XB3E.08 New Matching Metric Screw, Nut & Spacer Kits; M3 x 0.5 x 19MM, with 6MM Long Nylon Standoffs, for Electronic Component Mounting. Each bid quantity is for a Lot of Five (5) Kits. Each kit contains Four Screws, Four Matching Nuts, and Four Spacers. Thus, each bid quantity contains Twenty (20) Screws, Twenty (20) Nuts, and Twenty (20) Spacers [Total of Sixty Pieces]. You may bid / buy any number of lots, up to the total quantity available above. These were purchased at an electronics liquidation earlier this year, and they were brand new in unmarked plastic bags. Each kit comes in a tiny pink antistatic bag, and we over-packaged those in heavy Ziplok bags. These are ideal when you need to mount something small without buying a bunch of different components (and hoping everything matches). The threads are butter-smooth, and all components are top quality in every respect. According to the calipers: Overall screw length: 21.33 mm Screw length (underside of head to tip): 18.91 mm Screw threads: M3 x 0.5 x 19MM (diameter - thread pitch x standardized grip length) Head diameter: 5.49 mm Nut hex size: 5.43 mm Spacer diameter: 4.93 mm Spacer length: 6.00 mm
