Metric Flat Head (countersink) Socket Screw (Black Alloy Steel)
All of our Metric hardware is sold with the standard (popular) "pitch" (thread spacing) as follows:
(M2=.4) (M2.5=.45) (M3=.5) (M4=.7) (M5=.8)
For your information, approximately 25 millimeters equals 1 inch. The first number is the width and the second number is the length. As an example, an M3x25mm is 3 millimeters wide by about 1 inch long. Also, with Flat Head screws, the length is the total length of the screw including the head.
Notice as you scroll down the list that each size is listed twice, first the small pack, and then the larger economy pack.
