S-93880A199 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient thread-forming installation creates strong, permanent threads in sheet metal without requiring pre-tapped holes
• Dual-drive versatility with external hex/slotted head accommodates multiple tool types for flexible installation options
• Enhanced load distribution through integrated flange design (0.348" diameter) prevents pull-through and improves joint integrity
• Precise installation alignment with blunt tip design and No. 29 drill bit compatibility (0.136" diameter) reduces material splitting risk
• Full-length threading ensures maximum grip strength and uniform stress distribution along the entire 1" length
• Environmental compliance meets RoHS 3 standards for safe, regulated use in global manufacturing applications

Professional Applications & Engineering Value

These No. 8-18 thread-forming tapping screws deliver exceptional performance in sheet metal fabrication where traditional fastening methods fall short. The Type B thread-forming design displaces material to create strong, vibration-resistant threads without chip removal, eliminating the need for separate tapping operations and reducing assembly time. The zinc-plated steel construction provides reliable corrosion protection for HVAC systems, electrical enclosures, and automotive components exposed to harsh environments. With 0.164" thread diameter and 18 threads per inch, these hex head sheet metal screws maintain consistent clamping force while the external hex/slotted drive accommodates both manual and power tool installation, making them ideal for high-volume production lines and maintenance applications alike.

Specification Summary & Compliance

This No. 8-18 x 1" tapping screw features precise Unified thread standards with right-hand threading and fully threaded shank for maximum engagement. The fastener maintains dimensional accuracy with 0.164" thread diameter and 1/4" hex head width for consistent tool engagement. Manufacturing complies with RoHS 3 (2015/863/EU) regulations, ensuring environmental safety while delivering reliable performance in sheet metal fastening applications requiring No. 29 drill bit preparation (0.136" diameter).
