S-90822A587 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding industrial environments
• Enhanced fastening efficiency through the combination of thread forming design and drilling tip, eliminating the need for pre-drilling
• Maximum material penetration with 9/32" drill tip capable of drilling through materials up to 0.187" thick
• Secure installation and removal with external hex drive design providing excellent torque transmission and grip
• Reliable flange feature that distributes clamping pressure evenly and prevents loosening under vibration
• Full threading ensures consistent engagement and superior holding power across the entire fastener length
• Compliance assurance with RoHS 3 and REACH regulations for safe use in regulated industrial applications

Professional Applications & Engineering Value

These No. 12 flanged tapping screws deliver exceptional engineering value in steel, stainless steel, and sheet metal applications where traditional fastening methods fall short. The 410 stainless steel construction provides excellent strength and corrosion resistance, while the thread forming design creates strong, permanent threads in parent material without chip formation. The integrated drilling tip eliminates secondary operations, significantly reducing installation time and labor costs. The external hex drive ensures reliable torque application, and the flange design provides superior load distribution, making these BSD type screws ideal for vibration-prone environments and structural assemblies requiring consistent clamping force.

Specification Summary & Compliance

This No. 12 size tapping screw features a 1-1/4" length with fully threaded right-hand configuration and 14 threads per inch. The external hex drive measures 0.313" across flats with 0.194" head height, complemented by a 0.432" flange diameter for optimal load distribution. Manufactured to BSD screw type standards with precision thread forming capability, these industrial fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety in global industrial applications.
