About Flat Head Screws

These 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. All are passivated for added protection against oxidation and corrosion. They’re angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.

Metric 316 Stainless Steel Slotted Flat Head Screws

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. All are passivated for added protection against oxidation and corrosion, and they may be mildly magnetic. Screws are angled under the head to sit flush within countersunk holes. Length is measured from the top of the head.

Metric Steel Slotted Flat Head Screws

Flat Tip

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.

Zinc-plated screws have a layer of zinc that protects the steel from rust in wet environments and extends the life of the screw.

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.
