S-90821A357 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with galvanic barrier coated 18-8 stainless steel construction for extended service life in harsh environments
• Eliminates pre-drilling requirements thanks to the integrated drilling tip that penetrates up to 0.15" thick aluminum and sheet metal
• Enhanced grip and load distribution from the flanged hex head design, reducing the risk of loosening under vibration
• Faster installation and high clamp force with thread-forming BSD tapping method and fully threaded shank
• Secure external hex drive allows for high-torque application with standard tools, minimizing strip-out
• Reliable performance in aluminum and sheet metal applications due to precise No. 10-16 thread pitch and right-hand threading
• Compliance with environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries

Professional Applications & Engineering Value

These flanged hex head tapping screws are engineered to address common challenges in aluminum and sheet metal assembly, where corrosion resistance and installation efficiency are critical. The galvanic barrier coated 18-8 stainless steel material prevents galvanic corrosion when fastening dissimilar metals, while the thread-forming BSD design creates strong, permanent threads without pre-tapping, reducing labor time and tooling costs. The integrated drilling tip effortlessly penetrates up to 0.15" thickness, eliminating drill bit breakage and misalignment issues in high-volume production lines. Ideal for HVAC, automotive, and electronics enclosures, these screws deliver consistent corrosion-resistant performance where vibration resistance and long-term durability are paramount.

Specification Summary & Compliance

This No. 10-16 x 3/4" screw features a fully threaded shank with right-hand thread direction and 16 threads per inch, adhering to standard inch measurements. The external hex drive and flanged head ensure secure installation with common tools. Manufactured to meet industry standards for thread-forming tapping screws, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and material reliability for industrial use.
