Machine Screw Dimensions
Machine Screw Dimensions
(OP)
I'm trying to find dimensions for machine screws defined within ANSI B18.6.3. Mainly Phillips drive (cross recessed) are the ones I'm interested in. I have Machinery’s
Handbook 26 but it has dimensions for slotted machine screws.
If anyone has any reference material showing the dimensions of phillips head machine screws (82 and 100 degree flat head, pan head) it would be of help.
thanks.

The dimensions for phillips flat head machine screws are the same as for slotted. Try the following website...

These guys keep good drawings online. They even have good drawings of metric pan head (cheese head?) screws.

You will have to look to get fasteners made to this standard as most are now imported. It has been my experience that there is considerable difference in head height and slot depth on imported fasteners in the US.

If the matter is critical, it may be necessary to work directly with the manufacture to produce what you expect. If the matter isn't critical, then perhpas its not someting worth worrying about. :)
