①,Drilled hole shall be approximately perpendicular to the axis of slot and may be permitted to break through bottom of the slot. Edges of the hole shall be free from burrs.
②,A slight rounding of the edges at periphery of head shall be permissible provided the diameter of the bearing circle is equal to no less than 90% of the specified minimum head diameter.
⑤,The diameter of body on machine screws having other than trim heads shall not be less than the Class 2A thread minimum pitch diameter nor greater than the basic major diameter of the thread.
⑥,Machine Screw Length of Thread
1) Sizes No.5 and smaller.
Screws of nominal lengths equal to three diameters and shorter shall have full-form threads extending to within one pitch (thread) of the
bearing surface of the head, or closer, if practicable. Nominal lengths greater than three diameters, up to and including 1-1/8 in., shall have
full-form threads extending to within two pitches (threads) of the bearing surface of the head, or closer, if practicable. Screws of longer
nominal lengths shall, unless otherwise specified, have a minimum length of full-form thread of 1 in.
2) Sizes No.6 and smaller.
Screws of nominal lengths equal to three diameters and shorter shall have full-form threads extending to within one pitch (thread) of the
bearing surface of the head, or closer, if practicable. Nominal lengths greater than three diameters, up to and including 2 in., shall have
full-form threads extending to within two pitches (threads) of the bearing surface of the head, or closer, if practicable. Screws of longer
nominal lengths shall have a minimum length of full-form thread of 1.5 in. unless otherwise specified.
