S-94058A297 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant performance with zinc-plated 410 stainless steel construction for extended service life in harsh environments
• Integrated weather sealing through the stainless steel/rubber washer prevents moisture and debris ingress
• Eliminates pre-drilling requirements with self-drilling tip that penetrates up to 0.187" thick stainless steel and sheet metal
• Superior driving torque transfer via external hex head design for secure installation and removal
• Full-length thread engagement ensures maximum holding power across the entire 1-1/4" length
• Reliable thread forming action with BSD type design creates strong, permanent threads in parent material
• Industry-standard compatibility with No. 12-14 thread size and right-hand direction for broad application use

Professional Applications & Engineering Value

Engineered for demanding industrial fastening applications, these zinc-plated 410 stainless steel tapping screws deliver exceptional value in stainless steel and sheet metal assemblies. The combination of thread forming technology and integrated sealing washer addresses critical challenges in outdoor equipment, HVAC systems, and metal fabrication where weatherproofing and vibration resistance are paramount. The self-drilling tip significantly reduces installation time and labor costs by eliminating separate drilling operations, while the external hex drive ensures positive torque application during high-volume production. This BSD type tapping screw creates permanent, high-strength threads that resist loosening under dynamic loads, making it ideal for structural applications requiring long-term reliability.

Specification Summary & Compliance

This No. 12-14 thread forming screw features precision Class 2A thread tolerances with 0.216" thread diameter and 14 threads per inch. The fastener meets industry standards for BSD tapping screw applications in metal assemblies, with fully threaded design and right-hand thread direction. Manufacturing complies with relevant industrial specifications for tapping screws, while materials conform to RoHS and REACH environmental standards. The flat washer configuration with 0.563" OD provides optimal load distribution, and the No. 3 drill tip ensures consistent penetration performance up to the specified 0.187" maximum drilling thickness.
