CF Plate Nut Stainless Steel Vacuum SS304 Clamp for Semiconductor

CF flanges have tapped or untapped holes. Tapped flanges offer UNC/UNF or metric threading. They have through holes, letting bolts extend slightly beyond the flange back when secured to an untapped one. Untapped CF flanges can be connected using stainless steel bolts with hex nuts or plate nuts. Plate nuts self - center over two adjacent holes and can be steadied by one finger during bolt tightening. They're available for flange sizes from 1 1/3 to 10 inches (33.96 - 254mm) in outer diameter. For CF flanges with an outer diameter of 2 3/4 to 10 inches (33.96 to 354mm), 12 - point bolts can replace hex head bolts. Silver - plated bolts eliminate the need for anti - seize compound in clean rooms.
