Key Features & Benefits at a Glance
- Superior thread forming in aluminum without pre-drilling, reducing installation time and tooling requirements
- Exceptional strength-to-weight ratio with 7075 aluminum construction for demanding applications where corrosion resistance and durability are critical
- Integrated flange and hex head provides a larger bearing surface for secure fastening and prevents pull-through in softer materials
- Self-drilling tip (No. 2) efficiently penetrates aluminum sheets up to 0.106" thick, streamlining the assembly process
- Fully threaded right-hand design ensures maximum grip and consistent clamping force along the entire 1/2" length
- External hex drive allows for high-torque installation with standard tools, ideal for high-volume production environments
Professional Applications & Engineering Value
Engineered specifically for aluminum assemblies, these thread forming tapping screws solve common industrial challenges like galling and strip-out in soft metals. The 7075 aluminum material offers high tensile strength comparable to many steels while remaining lightweight and corrosion-resistant, making it perfect for aerospace, automotive, and electronics enclosures. The BSD (Thread Forming) design creates strong, clean threads in aluminum substrates without generating chips, eliminating debris contamination in sensitive applications. The combination of a flanged hex head and self-drilling tip creates a complete fastening system that reduces component count and installation steps, delivering significant time and cost savings in high-volume manufacturing operations.
Specification Summary & Compliance
This No. 10-16 screw features a 0.19" thread diameter with 16 threads per inch in a right-hand configuration. Manufactured to BSD (Thread Forming) standards with a Class 2A thread fit for reliable engagement. The 1/2" length and fully threaded design ensure consistent performance. Complies with industry standards for aluminum fasteners and is suitable for various industrial applications requiring heavy-duty tapping screws.
