S-90930A505 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance through zinc-plated steel construction, extending service life in demanding industrial environments
• Superior thread-forming capability with A/AB type design creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Optimized drive efficiency with No. 2 Phillips head providing secure tool engagement and reduced cam-out during installation
• Increased bearing surface from flanged pan head design distributes clamping force evenly, preventing material distortion
• Streamlined installation with pointed tip and fully threaded shank enabling quick starts and smooth penetration into No. 29 pre-drilled holes
• Reliable fastening performance with 15 TPI fine threads delivering superior holding power in thin sheet metal applications up to 0.025" thickness
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global manufacturing and environmental requirements

Professional Applications & Engineering Value

These zinc-plated steel tapping screws deliver exceptional value in sheet metal fabrication where vibration resistance and material integrity are critical. The thread forming technology eliminates the need for separate tapping operations while creating stronger, more durable threads that won't strip under stress. The flanged pan head design provides a wider bearing surface that prevents pull-through in thin gauge materials, making these Phillips drive screws ideal for HVAC systems, electronic enclosures, and automotive assemblies. With fully threaded construction and precise 0.164" diameter threads, these fasteners ensure maximum thread engagement and consistent clamping force across the entire 5/8" length, solving common challenges of loose fittings and material fatigue in industrial applications.

Specification Summary & Compliance

This No. 8 x 5/8" tapping screw features right-hand threading with 15 threads per inch and complies with standard thread forming specifications for A/AB type sheet metal screws. The fastener is engineered for use with No. 29 drill bits (0.136" diameter) in materials up to 0.025" thickness. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in global industrial markets.
