S-94058A129 Length 1 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Eliminates pre-drilling requirements with its integrated drilling tip that penetrates up to 0.15" thickness in stainless steel and sheet metal.
• Superior corrosion resistance is ensured by the Zinc-Plated 410 Stainless Steel construction and a sealing washer that blocks moisture ingress.
• Enhanced sealing and vibration resistance provided by the integrated stainless steel/rubber flat washer, protecting assemblies from loosening and environmental elements.
• High-strength thread forming (BSD) creates strong, durable threads in base materials, reducing the risk of stripping and ensuring a secure, long-lasting hold.
• Optimized for efficient installation featuring a standard external hex head for high-torque driving and a fully threaded 1-1/2" length for maximum grip.
• Built for heavy-duty industrial use with a robust No. 10-16 thread size, making it ideal for demanding construction and manufacturing applications.
• Guaranteed environmental and safety compliance, meeting RoHS 3 and REACH standards for safe use in regulated industries.

Professional Applications & Engineering Value

This heavy-duty tapping screw is engineered to solve critical fastening challenges in stainless steel and sheet metal assemblies. Its thread forming (BSD) design displaces material to create robust internal threads without cutting, which significantly reduces chip generation and increases joint integrity in ductile metals. The Zinc-Plated 410 Stainless Steel material provides an excellent balance of strength and corrosion resistance, essential for outdoor or harsh environment applications. The integrated sealing washer, composed of a stainless steel and rubber composite, acts as a gasket to prevent water and contaminant ingress, a common failure point in exposed structures. The self-drilling tip streamlines installation by combining drilling and tapping into a single operation, drastically cutting down on labor time and costs in high-volume industrial and construction projects.

Specification Summary & Compliance

This screw conforms to standard inch system dimensions: No. 10-16 thread (0.19" diameter, 16 TPI), a 1-1/2" length, and is fully threaded. The external hex head (0.313" width) ensures compatibility with common industrial drivers. It is manufactured as a BSD type thread forming tapping screw and is fully compliant with the environmental regulations RoHS 3 (2015/863/EU) and REACH (EC 1907/2006).
