S-94195A428 Length 7/8" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling with integrated No. 3 drill tip, saving significant labor time and tooling costs in steel and sheet metal assembly.
• Superior corrosion resistance from 410 Stainless Steel material, ensuring long-term reliability in demanding industrial and construction environments.
• Optimized for high-strength joints in materials up to 0.175" thick, providing secure, vibration-resistant fastening in sheet metal and steel applications.
• Streamlined installation with the Phillips Flat Head design and 82° countersink angle, allowing for a flush, professional finish that minimizes snagging.
• Enhanced thread integrity through the BSD thread forming process, which creates strong, strip-resistant threads without generating chips.
• Full-length threading maximizes grip and clamp force across the entire 7/8" length, improving joint stability.
• Broad material compatibility for use in steel, stainless steel, and sheet metal, offering versatile application across various projects.

Professional Applications & Engineering Value

This No. 14 self-drilling tapping screw is engineered to solve critical fastening challenges in metal fabrication and construction. The 410 Stainless Steel construction provides the necessary hardness and corrosion resistance for outdoor or harsh environment applications, while the specialized No. 3 drill tip and thread forming (BSD) technology work in tandem to penetrate and form precise threads in a single operation. This eliminates the common pain points of hole misalignment and tap breakage, drastically reducing assembly time and improving production throughput. The Phillips flat head with an 82° countersink ensures a clean, flush installation in pre-punched or drilled holes, making it an ideal sheet metal screw for HVAC, electrical enclosures, and structural steel connections where speed, strength, and a finished appearance are paramount.

Specification Summary & Compliance

This screw conforms to BSD (Thread Forming) standards with right-hand threads and a Class 2A thread fit for reliable engagement. The fully threaded #14-14 thread and precise 7/8" length ensure consistent performance. Manufactured from compliant 410 Stainless Steel, it meets industry expectations for material quality and is suitable for applications requiring good corrosion resistance. The product is manufactured in accordance with common industrial fastening specifications.
