  • Enhanced thread engagement with fully threaded BSD thread forming design for secure, vibration-resistant fastening
  • Clean, finished appearance provided by the standard oval head profile that sits flush with material surfaces
  • Optimized driving efficiency with Phillips No. 2 drive for reliable torque transmission and reduced cam-out
  • Maximum material penetration capability with 0.09" maximum drilling thickness for robust sheet metal applications
  • Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

These No. 6 x 1" 18-8 stainless steel oval head tapping screws deliver exceptional engineering value in demanding steel and sheet metal applications. The combination of thread forming BSD design and self-drilling tip eliminates multiple installation steps, significantly reducing assembly time and labor costs. The fully threaded configuration ensures maximum thread engagement along the entire shank length, providing superior pull-out resistance in thin-gauge materials. Manufactured from 18-8 stainless steel, these Phillips drive screws maintain structural integrity in corrosive environments while the oval head profile offers both aesthetic appeal and functional countersinking capability. These industrial fasteners are engineered to withstand vibration and thermal cycling while maintaining secure connections in HVAC systems, electrical enclosures, and metal fabrication projects.

Specification Summary & Compliance

These tapping screws feature precision No. 6 size with 0.138" thread diameter and 20 threads per inch in right-hand direction. The 1" length with fully threaded design and No. 2 drill tip (11/64" length) ensures consistent performance. Manufacturing complies with BSD tapping screw standards for thread forming applications. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) requirements, ensuring environmental safety and industrial reliability.
