Key Features & Benefits at a Glance
- Superior corrosion resistance with 410 Stainless Steel construction for long-lasting performance in demanding environments.
- Efficient thread forming technology creates strong, secure threads in parent material, reducing the risk of stripping and improving pull-out strength.
- Integrated drilling tip eliminates the need for pre-drilling, allowing for faster installation in steel, stainless steel, and sheet metal up to 0.09" thick.
- Secure square drive provides positive engagement with driving tools, minimizing cam-out and ensuring reliable torque transfer.
- Fully threaded right-hand design offers maximum grip and holding power along the entire 3/4" length for robust assemblies.
- Standard pan head with rounded profile ensures a low-profile, finished appearance while providing a good bearing surface.
- Compliant with major environmental regulations including RoHS 3 and REACH, ensuring they meet global safety and sustainability standards.
Professional Applications & Engineering Value
These No. 6 3/4" 410 Stainless Steel Tapping Screws are engineered to solve critical assembly challenges in metalworking and fabrication. The thread forming (BSD type) action cold-forms mating threads in ductile materials like steel, stainless steel, and sheet metal, creating a vibration-resistant connection superior to cut threads. The self-drilling No. 2 drill tip penetrates up to 0.09" thickness, streamlining production by combining drilling and fastening into a single operation. This eliminates alignment issues from separate drilling, reduces labor time, and minimizes tooling requirements. Manufactured from 410 Stainless Steel, they provide excellent strength and resistance to oxidation, making them ideal for applications where durability and corrosion resistance are paramount, from HVAC systems to industrial machinery enclosures.
Specification Summary & Compliance
This screw is a size No. 6 with a 0.138" thread diameter and 20 threads per inch. It features a fully threaded, right-hand design with a Class 2A thread fit. The drive is a Square, No. 1 size. The product conforms to the BSD standard for tapping screw types and is verified to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant.
