About Flat Head Screws

Metric Steel Slotted Flat Head Screws
Angled under the head, these metric screws fit in countersunk holes and sit flush with the surface of your part. Length is measured from the top of the head.
Screws with an extended tip, sometimes called a full dog point, fit into a hole or slot to keep parts such as pulleys and gears aligned. Use these screws in place of dowel pins; their threads clamp your parts down and keep them from rotating.
Screws with a black-oxide finish have mild corrosion resistance, but only in dry environments. DIN 925 and ISO 2009 (formerly DIN 963) screws meet international standards for fastener dimensions. ISO 2009 and DIN 963 are functionally equivalent with slight differences in head height, diameter, and thread length.
