S-90064A728 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Maximum torque transmission through external hex head design, preventing tool slippage during high-torque installation
• Efficient self-drilling capability with integrated No. 2 drill tip that eliminates pre-drilling requirements for up to 0.098" thick materials
• Enhanced load distribution from the integrated flange design that reduces surface pressure and prevents material deformation
• Reliable thread formation through BSD thread forming design that creates strong, vibration-resistant threads in sheet metal and steel
• Full-length fastening security with completely threaded shank that ensures consistent holding power along the entire screw length
• Industry-standard compatibility with No. 8-18 thread specifications for seamless integration into existing assembly processes

Professional Applications & Engineering Value

Engineered specifically for steel and sheet metal applications, these zinc-plated steel tapping screws deliver exceptional performance where traditional fasteners fail. The thread forming design creates permanent, vibration-resistant threads without generating chips, making them ideal for electrical enclosures, HVAC systems, and metal fabrication. The integrated drilling tip eliminates secondary operations, reducing installation time by up to 50% while the external hex drive ensures maximum torque transfer without cam-out. The flanged head design provides superior clamping force distribution, preventing material distortion in thin-gauge metals while the zinc plating offers reliable corrosion protection for both indoor and outdoor industrial environments.

Specification Summary & Compliance

These No. 8-18 thread forming screws feature precision BSD standard threads with 0.164" thread diameter and 18 threads per inch for consistent performance. Manufactured to industry standards for dimensional accuracy, the screws include fully threaded 7/8" length with Class 2A thread fit for reliable engagement. The construction complies with RoHS and REACH environmental standards while meeting industrial fastener specifications for material strength and performance in sheet metal and steel applications.
