S-98903A259 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh environments
• Excellent thread-forming capability creates secure, permanent threads in sheet metal without pre-tapping
• Optimized head design features undercut flat head for flush installation and reduced risk of material cracking
• Enhanced driving efficiency with No. 2 Phillips drive for secure tool engagement and reduced cam-out
• Maximum holding power through fully threaded design that distributes load evenly across the entire fastener length
• Precision dimensional control ensures consistent performance and reliable installation in sheet metal applications
• Environmental compliance meets RoHS 3 and REACH regulations for safe use in industrial settings

Professional Applications & Engineering Value

These No. 8-15 thread forming screws are specifically engineered for sheet metal assembly applications where reliable fastening is critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making them ideal for outdoor equipment, electrical enclosures, and HVAC systems. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, vibration-resistant connections. The undercut flat head profile ensures a flush finish without protrusions, while the Phillips drive system offers familiar, efficient installation for production line environments. These tapping screws solve common industrial challenges by providing consistent performance in thin materials where strip-out and loosening are frequent concerns.

Specification Summary & Compliance

These precision tapping screws feature a No. 8-15 thread configuration with 0.164" thread diameter and 15 threads per inch, designed for use with No. 29 drill bits (0.136" diameter). The flat head incorporates an 82° countersink angle and undercut profile for optimal seating in sheet metal applications. Manufactured to industry standards for thread forming screws, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet current environmental and safety requirements for industrial use across various sectors.
