Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 stainless steel construction for long-lasting performance in harsh environments
- Enhanced holding power through full-thread design and thread forming technology that creates stronger, more durable connections
- Wide truss head design provides larger bearing surface for improved load distribution and reduced material stress
- Optimized for sheet metal applications with precise No. 21 drill bit compatibility and 0.025" maximum drilling thickness capability
- Reliable Phillips No. 2 drive ensures secure installation and consistent torque application during assembly
- Precision thread forming (A/AB type) creates clean, tight-fitting threads without chip removal in sheet metal
- Comprehensive compliance with RoHS 3 and REACH regulations for safe, environmentally responsible industrial use
Professional Applications & Engineering Value
These 316 stainless steel tapping screws are engineered specifically for demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming technology eliminates the need for pre-tapped holes, creating stronger threads through material displacement rather than cutting. This results in superior pull-out resistance and vibration resistance in thin-gauge materials. The Phillips truss head design provides exceptional clamping force distribution, preventing material deformation while the fully threaded No. 10-12 configuration ensures maximum engagement along the entire 1-1/2" length. Ideal for HVAC systems, electronic enclosures, and industrial equipment where corrosion resistant fasteners must maintain integrity under mechanical stress and environmental exposure.
Specification Summary & Compliance
Manufactured to precise dimensional standards with 0.19" thread diameter and 12 threads per inch configuration. Features Class 2A thread tolerances for reliable fit and performance. The A/AB thread forming screw type ensures consistent thread engagement in sheet metal up to 0.025" thickness. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental safety and restricted substance compliance for industrial applications worldwide.
