Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws are specifically engineered for sheet metal applications where reliable fastening is critical. The thread-forming design eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating strong, permanent threads in metal substrates. The A/AB tapping screw type with pointed tip ensures easy starting and smooth thread formation, minimizing the risk of material splitting or stripping. The combination of zinc-plated corrosion protection and fully threaded construction provides exceptional resistance to vibration loosening and environmental degradation, making these industrial screws ideal for HVAC systems, electrical enclosures, automotive components, and metal fabrication projects where durability and performance are paramount.

Specification Summary & Compliance

These sheet metal screws feature precision thread forming with 0.164" thread diameter and 15 threads per inch, designed for use with No. 29 drill bits (0.136" diameter) in materials up to 0.025" thickness. The tapping screws comply with industry standards for thread forming applications and maintain regulatory compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, ensuring they meet current industrial safety and substance restriction requirements for professional use.
