Types of Stainless Steel Self Drilling Screws We Offer

Stainless Steel 410 Self Drilling Screw

These self drilling screws are made from stainless steel 410, a martensitic alloy that can be hardened for strength and wear resistance. Their drill points penetrate light- and medium-gauge steel, eliminating the need for pre-drilling. They are commonly used in roofing, siding, and steel framing projects. Stainless steel 410 provides a balance of hardness for drilling performance and corrosion resistance for long-term use.

Stainless Steel 410 Self Drilling Screw Indented Hex Washer Head Unslotted with Bonded Washer

These screws feature indented hex washer heads for strong torque transfer and reliable installation. The bonded washer design combines a steel washer with an EPDM sealing layer, preventing leaks in roofing and siding applications. Manufactured from stainless steel 410, these screws offer strength for drilling into structural steel along with corrosion resistance for outdoor use. They are trusted in construction projects where water resistance and secure fastening are critical.

Material Options

South Coast Fasteners stocks stainless steel self drilling screws in materials that deliver hardness, wear resistance, and corrosion protection.

Stainless Steel 410

Stainless steel 410 is a martensitic grade that can be heat-treated for hardness. It provides the drilling ability necessary for self drilling screws, ensuring fast penetration into steel and structural members. While it does not have the same corrosion resistance as 316, stainless steel 410 is strong enough for roofing, siding, and many outdoor applications where hardness is as important as rust resistance.

EPDM Bonded Washers

Anchors paired with EPDM bonded washers provide sealing capabilities in addition to holding strength. EPDM rubber resists weathering, UV exposure, and temperature fluctuations, making it ideal for roofing and siding projects. Combined with stainless steel 410 screws, bonded washers extend the life of fastened assemblies.

Available Finishes

South Coast Fasteners offers stainless steel self drilling screws in their natural alloy finish and with accessory components for added performance.

Bonded Washer Assembly

Bonded washer assemblies combine a metal washer and EPDM rubber to create a watertight seal under the screw head. This finish option is used in roofing, siding, and outdoor structural work where water penetration must be prevented. It enhances the performance of stainless steel screws by protecting the fastening point.
