S-90048A151 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in harsh industrial environments.
• Effortless installation thanks to the thread forming design and pointed tip, reducing assembly time and tool wear.
• Secure fastening in sheet metal with a standard 82° flat head profile, providing a flush finish and reliable hold.
• High torque transmission from the Phillips No. 2 drive, minimizing slippage and enhancing driving efficiency.
• Consistent thread engagement with fully threaded 18 TPI design, ensuring uniform load distribution and vibration resistance.
• Wide compatibility for use with No. 32 drill bits, simplifying hole preparation and improving application versatility.
• Compliance with global standards including RoHS 3 and REACH, guaranteeing safety and environmental responsibility.

Professional Applications & Engineering Value

These zinc-plated steel tapping screws are engineered to address common challenges in sheet metal applications, such as material fatigue and loosening under stress. The thread forming method creates strong, permanent threads without chips, reducing the risk of contamination in sensitive assemblies. With a Phillips flat head and standard 82° countersink, they sit flush to prevent snagging and improve aesthetics in HVAC, automotive, and electronics enclosures. The fully threaded No. 6 x 3/4" design ensures maximum grip across the entire length, ideal for securing thin-gauge metals up to 0.025" thick. By combining ease of use with robust zinc-plated protection, these screws minimize maintenance and extend service life in demanding industrial settings.

Specification Summary & Compliance

This tapping screw adheres to Class 2A thread tolerances for reliable fit, with a thread diameter of 0.138" and 18 TPI. It conforms to A/AB tapping screw standards for thread forming applications and features a right-hand thread direction. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety requirements for industrial use.
