Professional Applications & Engineering Value

These No. 8-15 TPI thread forming screws are specifically engineered for demanding sheet metal applications where reliability is critical. The 18-8 stainless steel composition provides excellent resistance to corrosion and oxidation, making these flat head tapping screws ideal for outdoor equipment, electrical enclosures, and HVAC systems. The thread forming design eliminates the need for tapping operations by cold-forming mating threads directly into the material, creating stronger thread engagement than conventional cutting screws. This square drive configuration prevents stripping and ensures consistent installation torque, while the standard 82° countersink angle allows for seamless flush mounting in precision metal fabrication projects. The combination of 0.164" thread diameter and 15 threads per inch provides optimal balance between holding strength and installation efficiency in various gauge metals.

Specification Summary & Compliance

This No. 8-15 x 2" flat head tapping screw features precision Class 2A thread tolerances with right-hand threading and fully threaded shank design. Manufactured to industry standards for thread forming (Type A/AB) tapping screws, it maintains dimensional accuracy with 0.312" head diameter and 0.1" head height. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. Maximum drilling thickness is specified at 0.025" with recommended No. 29 drill bit (0.136" diameter) for optimal performance in sheet metal applications.
