Key Features & Benefits at a Glance
- Superior corrosion resistance with 410 Stainless Steel construction, ideal for harsh industrial environments
- Maximum torque transmission through the external hex drive design, preventing stripping during high-torque applications
- Eliminates pre-drilling requirements with the integrated drilling tip that penetrates up to 0.187" thick materials
- Secure, vibration-resistant fastening thanks to the thread forming BSD method and flanged design
- Full-length holding power with the fully threaded shank for consistent grip along the entire 2-1/2" length
- Broad material compatibility for steel, stainless steel, and sheet metal applications
- Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use
Professional Applications & Engineering Value
Engineered for demanding industrial fastening, these No. 12 flanged tapping screws deliver exceptional value in steel, stainless steel, and sheet metal assemblies. The 410 Stainless Steel material provides excellent corrosion resistance, while the thread forming BSD method creates stronger, more secure threads that resist vibration loosening. The integrated drilling tip eliminates secondary operations, significantly reducing installation time and labor costs in high-volume production environments. The external hex drive ensures reliable torque transmission without cam-out, making these fully threaded screws ideal for structural applications requiring maximum pull-out strength and long-term reliability in challenging conditions.
Specification Summary & Compliance
This heavy-duty tapping screw features a No. 12 size with 0.216" thread diameter and 14 TPI right-hand threads. The 2-1/2" length fully threaded design with Class 2A thread tolerances ensures precise fitment. Manufactured to BSD tapping screw standards with thread forming technology, the fastener demonstrates compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmentally responsible industrial use.
