Professional Applications & Engineering Value
These 316 stainless steel tapping screws provide exceptional value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming tapping method eliminates the need for separate tapping operations, reducing installation time while creating strong, vibration-resistant connections. The fully threaded design ensures maximum holding power across the entire fastener length, making them ideal for joining thin gauge materials up to 0.025" thickness. The Phillips No. 2 drive offers reliable torque transfer during installation, while the 82° countersink angle provides a clean, flush finish that meets professional appearance standards in HVAC, electrical enclosures, and industrial equipment manufacturing.
Specification Summary & Compliance
This No. 8-15 x 1-1/2" tapping screw features precision Class 2A thread tolerances with A/AB thread form specification. The fastener meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) standards, ensuring environmental responsibility in industrial applications. Manufactured to industry standards for sheet metal fastening with recommended No. 29 drill bit (0.136" diameter) for optimal thread formation and holding strength.
