PACKAGE INCLUDED: This comprehensive assortment kit includes 180 pieces of #8 sheet metal screws in various sizes: 50pcs #8 x 3/4", 40pcs #8 x 1", 30pcs #8 x 5/8", 30pcs #8 x 1/2", 15pcs #8 x 1-1/4", and 15pcs #8 x 1-1/2". All screws are crafted from durable stainless steel with a silver finish. SELF DRILLING SCREWS: Designed for efficiency, these screws feature a drill-bit-shaped tip that eliminates the need for a pilot hole, significantly saving time during installation. They are ideal for metal-to-metal or metal-to-wood connections, making them perfect for thin metal applications. DURABLE 410 STAINLESS STEEL MATERIAL: Constructed from 410 stainless steel, these self-tapping screws are corrosion resistant and rustproof, ensuring a long-lasting performance. The high strength of this material prevents deformation, making it suitable for a variety of demanding tasks. WIDE APPLICATION: The versatility of these self-drilling screws allows for use in a range of materials including metal, wood, and plastic. They are commonly employed in metal roofing, HVAC installations, ductwork, and steel framing, effectively securing various components. FINE WORKMANSHIP: Featuring a modified truss head with a Phillips drive, these screws provide a larger surface area to distribute force evenly. This design enhances holding power and minimizes the risk of slipping, ensuring a strong and reliable connection. Product Description Myth 1: All Stainless Steel is Non-magnetic Reality: Stainless steel comes in various alloys, and its magnetism depends on the specific alloy composition. There are magnetic types and non-magnetic types. Myth 2: Stainless Steel Rusts If It?s Magnetic Reality: Magnetic stainless steel alloys can still resist rust and corrosion, just like their non-magnetic counterparts. Magnetism does not dictate corrosion resistance. Stainless Steel Types: Ferritic, such as 409, 430, 439. Magnetic Austenitic, such as 304, 316. Non-Magnetic or weak magnetic
