Key Features & Benefits at a Glance
- Self-drilling capability eliminates pre-drilling requirements, saving time and labor costs in steel and sheet metal applications
- Zinc-plated steel construction provides excellent corrosion resistance for extended service life in industrial environments
- Oval head design with 82° countersink angle creates a flush, professional finish while distributing clamping force evenly
- Thread forming BSD design creates strong, permanent threads in base materials without chip formation
- Phillips No. 2 drive ensures secure tool engagement and efficient installation with common industrial drivers
- Fully threaded 1-1/2" length delivers maximum holding power and pull-out resistance across the entire fastener
- 0.1" maximum drilling thickness handles standard gauge steel and sheet metal with reliable penetration
Professional Applications & Engineering Value
These No. 8 x 1-1/2" zinc-plated steel oval head tapping screws solve critical fastening challenges in metal fabrication and construction. The integrated self-drilling tip (No. 2 drill type) penetrates up to 0.1" thickness without pilot holes, streamlining assembly processes in steel and sheet metal applications. The thread forming BSD design creates precise, cold-formed threads that resist vibration loosening while maintaining material integrity. The oval head profile with standard dimensions provides both aesthetic appeal and functional countersinking, making these Phillips drive screws ideal for HVAC systems, electrical enclosures, and structural metal assemblies where reliability and efficiency are paramount.
Specification Summary & Compliance
These industrial fasteners feature precise 0.164" thread diameter with 18 threads per inch and fully threaded design for consistent performance. Manufactured to BSD tapping screw standards with right-hand thread direction and round shank cross-section. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
