S-90064A622 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Efficient installation with external hex drive and hex head design providing excellent torque transmission and tool engagement
• Exceptional holding power through BSD thread forming technology that creates strong, permanent threads in base materials
• Reduced assembly steps with integrated drilling tip that penetrates up to 0.21" thickness without pre-drilling
• Enhanced stability from flanged design that distributes clamping force and prevents pull-through
• Full thread engagement with completely threaded shank for maximum grip along the entire fastener length
• Reliable performance in steel and sheet metal applications with No. 3 drill tip optimized for material penetration

Professional Applications & Engineering Value

These 1/4"-14 zinc-plated steel tapping screws deliver exceptional engineering value by eliminating multiple assembly steps in steel and sheet metal applications. The combination of thread forming technology and integrated drilling tip allows for direct installation without pre-tapping or pilot holes, significantly reducing labor time and costs. The BSD thread forming design creates precise, cold-formed threads that provide superior resistance to vibration loosening compared to conventional fasteners. The zinc-plated steel construction ensures reliable performance in environments where corrosion resistance is critical, while the flanged hex head design offers improved load distribution and eliminates the need for separate washers. These features make them ideal for manufacturing, construction, and metal fabrication where fast, secure fastening is essential.

Specification Summary & Compliance
