S-98392A610 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with protective coating extends service life in demanding environments
• Integrated rubber/steel sealing washer creates reliable moisture and dust barriers in sheet metal and wood applications
• Thread forming needle point design eliminates chips and ensures secure, vibration-resistant fastening
• External hex head with 1/4" width provides excellent torque transmission for efficient installation
• Fully threaded 2-1/2" length delivers maximum grip depth and holding power across materials
• Precision 12 threads per inch maintains consistent engagement and prevents stripping
• Pre-drilling compatibility with No. 21 drill bit simplifies installation in various materials

Professional Applications & Engineering Value

This No. 10 hex head sealing tapping screw addresses critical challenges in sheet metal fabrication and wood construction where environmental sealing and vibration resistance are paramount. The corrosion-resistant coated steel construction withstands harsh conditions while the thread forming needle type design creates stronger threads without material removal, eliminating chip contamination issues. The integrated rubber/steel washer provides dual-function performance - the steel component distributes load evenly while the rubber element compresses to form permanent seals against moisture and contaminants. With fully threaded engagement and 0.19" thread diameter, engineers achieve maximum pull-out resistance in applications ranging from HVAC ductwork to outdoor wooden structures.

Specification Summary & Compliance

This thread forming tapping screw features precision right-hand threads with standard inch measurements: No. 10 screw size, 2-1/2" length, and 12 threads per inch. The external hex drive (1/4" head width) ensures compatibility with standard tools. Manufactured to industry standards for tapping screws, it's designed for use with No. 21 drill bit (0.159" diameter) in materials up to 0.036" thickness. The corrosion-resistant coating and sealing washer construction meet industrial requirements for durable fastening solutions in demanding applications.
