S-90197A198 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-term durability in harsh industrial environments
• Enhanced holding power through thread forming technology that creates strong, permanent threads in sheet metal without pre-tapping
• Quick and easy installation with the external hex/slotted drive combination and pointed tip for precise starting alignment
• Increased bearing surface from the integrated flange design, distributing load evenly and preventing pull-through in thin materials
• Optimal thread engagement with fully threaded shank and 15 threads per inch, providing maximum grip in 0.05" maximum thickness materials
• Reliable industrial compliance meeting RoHS 3 and REACH environmental standards for safe, sustainable manufacturing operations
• Versatile sheet metal fastening specifically engineered for No. 29 drill bit applications with 0.136" diameter holes

Professional Applications & Engineering Value

These No. 8 zinc-plated steel tapping screws deliver exceptional performance in sheet metal fabrication and assembly operations. The thread forming needle point design eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating stronger, more reliable connections. The hex head with external drive provides superior torque transmission for high-speed assembly applications, while the flanged design eliminates the need for separate washers, streamlining inventory and reducing component count. Engineered for sheet metal applications up to 0.05" thickness, these fully threaded screws maintain consistent clamping force across the entire engagement length, preventing loosening from vibration and thermal cycling in industrial equipment, HVAC systems, and electronic enclosures.

Specification Summary & Compliance

This No. 8 x 3/4" tapping screw features precise 0.164" thread diameter with 15 threads per inch and right-hand threading conforming to standard industrial specifications. The hex head measures 1/4" across flats with 0.141" height, compatible with standard driving tools. Manufactured from zinc-plated steel with fully threaded shank and pointed tip for optimal performance in sheet metal applications using No. 29 drill bits (0.136" diameter). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
