• Undercut flat head profile ensures flush mounting with 82° countersink for clean, professional finishes in metal assemblies
• Precision Phillips No. 2 drive provides reliable torque transmission and reduces cam-out during installation
• Fully threaded No. 8 shank with 0.164" diameter and 15 TPI offers maximum grip length and holding power in thin materials
• Optimized for 0.025" maximum thickness sheet metal applications with recommended No. 29 drill bit for perfect fit
• Compliant with RoHS 3 and REACH regulations ensuring environmental safety and global market acceptance

Professional Applications & Engineering Value

These 316 stainless steel flat head Phillips tapping screws deliver exceptional performance in demanding sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for separate tapping operations, creating strong, strip-resistant threads that maintain holding power in thin-gauge materials up to 0.025" thickness. The undercut flat head with 82° countersink angle provides a flush finish that prevents snagging while distributing clamping force evenly. Engineered with fully threaded No. 8 shanks and precise 15 TPI threading, these screws offer superior pull-out resistance in HVAC systems, electronic enclosures, automotive components, and industrial equipment where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These tapping screws feature precision 0.164" thread diameter with 15 TPI thread forming design, manufactured to standard tolerances for consistent performance. The Type A/AB tapping screw configuration ensures proper thread engagement in sheet metal applications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and restricted substance compliance. The 3/8" length and No. 8 screw size provide optimal fastening solutions for standard sheet metal thicknesses when used with the recommended No. 29 drill bit (0.136" diameter).
