FHSCS protrude from the surface

[ifuks]

I noticed it is not fixed in IV 2009. If countersink clearance hole is created for inch screw and then standard flat head socket cup screw is inserted it protrudes .01-.02 from the surface. To fix this hole feature needs to be edited manually. I understand that excel file can be modified to edit definition but then why not let ADSK do it? Am I missing something here?

Because the actual height of the flat head is different for a socket head versus regular (slotted or phillips) screws.

Like for example the height of the flat head socket cup screw for 3/4" is .396 but a regular flat head height is .372

Don't blame autodesk, blame ANSI or whomever first dimensioned screws.
For autodesk to fix it correctly they need to have different options for countersink height/diameter based on head types used.

They have "Fastener type" to take care of that. There is "Flat Head Machine Screw(82)" and "Flat Head Machine Screw(100)". Why not to add "Flat Head Socket Cap Screw"? There is only 6 fastener types available in this dialog. They should at least cover all fastener types they put in CC. This is not idle complaint by the way. This is a GOTCHA build in IV that one should be aware of. Stuff like that causes costly mistakes. How would you like to design heat treated flat skid plate attached with FSHCS and then find that screws protrude? Makes for a good chuckle on the shop floor.

Thanks for your answer.
