S-90056A197 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant zinc-plated steel construction ensures long-term durability in humid or demanding industrial environments.
• Thread forming Type B design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and tooling costs.
• Phillips No. 2 drive provides secure, cam-out resistant engagement for efficient installation with standard tools.
• Fully threaded blunt tip allows for smooth, consistent penetration and maximum holding power across the entire fastener length.
• Standard pan head with 0.322" diameter offers a low-profile, rounded finish that sits flush and resists snagging.
• Precise No. 8-18 thread with 0.164" diameter delivers reliable grip and vibration resistance in sheet metal applications.
• RoHS 3 compliance guarantees environmental safety and meets international regulatory standards for hazardous substances.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered specifically for sheet metal assemblies where reliability and speed are critical. The thread forming Type B design displaces material to form robust internal threads, eliminating the need for separate tapping operations and reducing the risk of strip-out in thin-gauge metals. With a Phillips drive and blunt tip, installation is streamlined, minimizing operator fatigue and ensuring consistent seating. The fully threaded shank and 0.164" diameter provide uniform load distribution, making these screws ideal for HVAC, electrical enclosures, and automotive panels where vibration resistance and long-term integrity are paramount. Their RoHS 3 compliant finish further supports use in regulated industries, offering a dependable industrial fastener solution that enhances production efficiency.

Specification Summary & Compliance

This No. 8-18 x 3/4" tapping screw features a right-hand thread with approximately 18 threads per inch and is designed for use with a No. 29 drill bit (0.136" diameter). It complies with RoHS 3 (2015/863/EU) regulations, ensuring it is free from restricted hazardous substances. The screw's thread forming method and fully threaded configuration adhere to industry standards for sheet metal fastening, providing consistent performance and ease of integration into professional assembly processes.
