About Rounded Head Screws

Metric Alloy Steel Flanged Button Head Screws

These metric alloy steel screws are nearly twice as strong as stainless steel button head screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.

Metric 18-8 Stainless Steel
Flanged Button Head Screws

Made from 18-8 stainless steel, these metric screws have good chemical resistance and may be mildly magnetic. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.

Metric 316 Stainless Steel Flanged Button Head Screws

These metric 316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer. Screws may be mildly magnetic.

Metric Stainless Steel Ultra-Wide
Flanged Button Head Screws

These metric 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

Metric Extra-Wide Flanged Button Head Screws

With a flange comparable in size to a washer, these metric screws distribute pressure better than standard flanged screws. Made from 316 stainless steel, they have excellent resistance to chemicals and salt water. Screws may be mildly magnetic.

Metric Aluminum Ultra-Wide
Flanged Button Head Screws

Made from aluminum, these metric screws are lightweight and resist corrosion in wet environments. The flange is wider and thicker than our other flanged screws, so they distribute pressure the best.

Flanged Socket Head Screws

These general purpose flanged screws distribute pressure where the screw meets the surface, eliminating the need for a washer.

Serrated-Flange Socket Head Screws

Serrations under the head grip the material's surface for mild vibration resistance. The flange distributes pressure across the material's surface, eliminating the need for a washer.
