Rounded Head Screws

18-8 Stainless Steel Extra-Wide
Truss Head Phillips Screws

These 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. The extra-wide truss head distributes holding pressure to reduce the likelihood of crushing thin material.

Metric 18-8 Stainless Steel Extra-Wide
Truss Head Phillips Screws

Made from 18-8 stainless steel, these metric screws have good chemical resistance and may be mildly magnetic. The extra-wide truss head distributes holding pressure to reduce the likelihood of crushing thin material.

316 Stainless Steel Extra-Wide
Truss Head Phillips Screws

More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water. The extra-wide truss head distributes holding pressure to reduce the likelihood of crushing thin material. Screws may be mildly magnetic.

Metric 316 Stainless Steel Extra-Wide
Truss Head Phillips Screws

These metric 316 stainless steel screws resist corrosion from chemicals and salt water better than 18-8 stainless steel screws. The extra-wide truss head distributes holding pressure to reduce the likelihood of crushing thin material. Screws may be mildly magnetic.

Low-Profile Ultra-Wide Truss Head Slotted Screws

When head height is important, these screws fit into spaces where other wide head screws won't fit. Also known as shutter screws, their ultra-wide truss head distributes the load over a large area for excellent holding pressure.

Metric Low-Profile Ultra-Wide
Truss Head Slotted Screws

Fit these metric screws into spaces where head height is important and other wide head screws won't fit. Also known as shutter screws, they have an ultra-wide truss head to distribute the load over a large area for excellent holding pressure.

Steel Extra-Wide Truss Head Slotted Screws

A zinc plating provides mild corrosion resistance.

Stainless Steel Extra-Wide
Truss Head Slotted Screws

Stainless steel screws have excellent corrosion resistance in most environments.

Sanitary Extra-Wide Truss Head Screws

Designed for use in food, pharmaceutical, and other sanitary environments, these screws have an extra-wide truss head that distributes holding pressure to reduce the likelihood of crushing thin materials.
