Stainless Steel Hex Head Self Drilling Screw with EPDM Washer

Stainless Steel Hex Head Self Drilling Screw with EPDM Washer is a high-performance fastener widely used for fixing metal sheets, roofing panels, and cladding materials to steel or aluminum structures. Manufactured by Yellow Enterprises, Pune, these screws combine superior strength, long-term corrosion resistance, and weatherproof sealing — ideal for industrial and architectural installations.

Self-drilling screws are designed with a built-in drill point, eliminating the need for pre-drilling. The EPDM (Ethylene Propylene Diene Monomer) washer attached beneath the head provides a watertight seal and excellent vibration absorption, ensuring strong, leak-proof joints even under extreme environmental conditions.

Founded in 2017 and headquartered in Pune, Maharashtra, India, Yellow Enterprises is a recognized manufacturer and supplier of premium-grade stainless steel fasteners. The company specializes in Stainless Steel Blind Self Clinch Nuts, Self Drilling Screws, Machine Screws, and various custom fastener solutions for industrial, construction, and engineering applications.
