More corrosion resistant than steel, and almost as strong, these 18-8 stainless steel screws have a narrower head than pan head screws to fit into tight spaces. They’re often used in electrical panels and next to flanges and raised surfaces in humid, damp, and washdown environments, but will corrode if exposed to salt water or chemicals. A deep slot gives you more driving power and keeps the screwdriver from slipping. Length is measured from under the head.

Passivated screws are finished with an extra layer of rust protection.

ISO 1207 (formerly DIN 84), DIN 920, and DIN 922 screws meet international standards for fastener dimensions.

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.

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.
