Professional Applications & Engineering Value
These No. 8 x 2" oval head tapping screws deliver exceptional performance in demanding sheet metal applications where reliability is critical. The 18-8 stainless steel composition provides outstanding corrosion resistance, making them suitable for outdoor equipment, electrical enclosures, and HVAC systems. The thread forming (A/AB) design eliminates the need for separate tapping operations, reducing assembly time and labor costs while creating stronger, vibration-resistant connections. The Phillips No. 2 drive ensures consistent installation with standard tools, while the fully threaded configuration and 15 TPI pitch provide maximum engagement in thin materials. The oval head profile with 82° countersink offers both aesthetic appeal and functional flush mounting, preventing snagging in finished products.
Specification Summary & Compliance
These thread forming tapping screws feature precision Class 2A thread tolerances with 0.164" thread diameter and 15 threads per inch. Manufactured to A/AB tapping screw standards with right-hand threading and pointed tip for easy starting. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial applications worldwide. Designed specifically for use with No. 29 drill bit (0.136" diameter) in materials up to 0.025" thickness.
