Bimetal 304 316 Stainless Steel Self Drilling Screws With EPDM Washers| Metal Roofing Fastening Screws

Bimetal 304 316 Stainless Steel Self Drilling Screws combine the advantages of stainless steel corrosion resistance and high-strength drilling capability. The stainless steel body provides excellent protection against moisture, salt spray, and harsh environments, while the hardened alloy steel drill point ensures efficient drilling performance on steel sheets and metal structures.

Compared with traditional stainless steel self drilling screws, bimetal screws overcome the limitation of insufficient hardness in stainless steel drill points. The specially designed composite structure allows the screws to achieve better drilling ability, longer service life, and more reliable fastening performance.

Available in 304 and 316 stainless steel materials, these screws are suitable for metal roofing systems, solar photovoltaic installations, steel structures, industrial manufacturing, and outdoor construction projects where corrosion resistance and installation efficiency are both important.

As a professional bimetal screw manufacturer, we provide customized solutions including different diameters, lengths, head styles, thread designs, coatings, and packaging options to meet various industrial and engineering requirements.
