THREAD SIZE AND LENGTH SELECTION DATA

TYPE M-CSS, M-CSOS (stainless steel standoffs)

Thread lengths

(1) Blind mounting holes may be deeper than minimums except where sheet material is at or near minimum thickness. Fasteners should always be installed so the flange is flush with the surface of the sheet.

(2) For shorter standoff lengths, when "L" is less than "T" minimum thread depth will be equal to "L". Screws with lengths exceeding "L" should not be used for they may cause "jacking-out" of standoff from the sheet.

(3) Type M-CSS and M-CSOS are blind at hex end.
