Designed for efficiency and durability, the Light Section variant is ideal for 1.2mm - 3.5mm steel, while the Heavy Section is suited for 4.0mm - 12.5mm steel applications. Made from carbon steel AISI C1022, these screws feature super-hard, ultra-sharp drill tips for rapid penetration and reduced installation time. The countersunk head with nibs ensures a flush finish, while precision-formed concave fluting allows for quick chip removal. Additionally, the aggressive thread design provides excellent tapping performance and secure holding power.
