Key Features & Benefits at a Glance
- Eliminates pre-tapped holes with thread forming design, reducing installation time and tooling costs in sheet metal assemblies.
- Enhanced corrosion resistance from Black-Oxide Steel finish, ensuring long-term reliability in demanding industrial environments.
- Secure, slip-resistant fastening with Phillips No. 2 drive, providing consistent torque transfer and reducing cam-out risks.
- Full-length threading and pointed tip for faster starts and superior grip across the entire 3/4" length in sheet metal up to 0.025" thickness.
- Precision-engineered A/AB thread form delivers high pull-out strength and vibration resistance in right-hand applications.
- Compliance with RoHS 3 and REACH standards ensures environmental safety and meets global regulatory requirements for industrial components.
- Optimized for No. 29 drill bits (0.136" diameter), enabling precise pilot holes and reducing material stress during installation.
Professional Applications & Engineering Value
These No. 8 x 3/4" Black-Oxide Steel tapping screws are engineered to solve common challenges in sheet metal fabrication, such as stripped threads and assembly delays. The thread forming (A/AB) design creates strong, clean threads in pre-drilled holes without tapping, minimizing metal shavings and improving joint integrity. The Phillips pan head offers a low-profile, flush finish while the Black-Oxide coating adds a protective layer against rust and wear. Ideal for HVAC systems, electronic enclosures, and automotive panels, these screws ensure vibration-resistant, durable fastening in high-stress environments, streamlining production and reducing maintenance needs.
Specification Summary & Compliance
This tapping screw features a 0.164" thread diameter with 15 threads per inch and a Class 2A fit for standard industrial tolerances. Manufactured to A/AB thread forming standards with a fully threaded, pointed tip and 3/4" length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety guidelines for industrial fasteners.
