S-90420A450 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant performance with galvanic-barrier coated 18-8 stainless steel construction for extended service life in harsh environments
• Self-drilling capability with integrated steel tip eliminates pre-drilling, reducing installation time and labor costs
• Superior thread engagement through thread forming design creates strong, vibration-resistant connections in steel and sheet metal
• Enhanced load distribution from the integrated flange design provides wider bearing surface and prevents pull-through
• High drilling capacity with 0.15" maximum thickness penetration for versatile application across multiple material types
• Secure fastening with fully threaded shank ensures maximum grip length and holding power throughout the connection
• Industry compliance with RoHS 3 and REACH regulations ensures environmental responsibility and global market acceptance

Professional Applications & Engineering Value

These hex flange tapping screws deliver exceptional value in industrial fastening applications where corrosion resistance and installation efficiency are critical. The galvanic-barrier coated 18-8 stainless steel construction prevents galvanic corrosion when joining dissimilar metals, while the self-drilling tip technology eliminates secondary drilling operations in steel, stainless steel, and sheet metal assemblies. The thread forming design creates precise mating threads without generating chips, resulting in superior pull-out strength and vibration resistance. With the external hex drive and flange configuration, installers achieve higher torque application and improved clamp load distribution, making these BSD tapping screws ideal for HVAC systems, electrical enclosures, and metal fabrication where reliability and speed of installation drive operational efficiency.

Specification Summary & Compliance

This No. 10-16 x 3/4" tapping screw features precision right-hand threads with 16 TPI and 0.19" thread diameter, manufactured to industry standards for thread forming screws. The fully threaded shank and No. 3 drill tip design ensure consistent performance across the specified 0.15" maximum drilling thickness. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms environmental responsibility and material safety standards for industrial applications worldwide.
