About Rounded Head Screws

Standard Head

Good for use outdoors and in washdown environments, these metric 18-8 stainless steel screws are more corrosion resistant than steel and nearly as strong. Their pan-shaped head sits nearly flat on the fastened surface, so there’s no need to countersink a hole. With domed or chamfered edges, the head of these screws won’t snag clothing when you brush against it. Length is measured from under the head.

Standard-head screws are better for applications with tight spaces than wide-head screws. They meet ISO 1580 (formerly DIN 85), which are dimensional and material standards recognized globally.

Passivated screws have extra protection against oxidation and corrosion.

Metric Steel Pan Head Slotted Screws

Standard Head

Install these metric pan head screws for a low-profile, finished look—no countersink required. With a chamfered or slightly domed head, they won't catch on clothing or straps as you pass by. A layer of zinc plating protects the steel from rust in wet areas but won't hold up to salt water and chemicals. Length is measured from under the head.

All of these screws meet DIN or ISO dimensional and material standards, so you know they'll fit with other parts and tools. Although DIN 85 is no longer active and has been superseded by ISO 1580, it's still a relevant standard that's referenced by engineers and designers. The two standards are functionally equivalent.
