S-90065A148 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ideal for harsh environments and long-term reliability.
• Efficient thread forming with Type A design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time.
• Secure and flush installation thanks to the standard flat head with 82° countersink angle, providing a smooth surface finish.
• Optimized drive engagement using a Phillips No. 2 drive style, minimizing cam-out and ensuring consistent torque application.
• Full-length threading maximizes grip and load distribution across the entire 1/2" length in sheet metal applications.
• Precision compatibility with No. 32 drill bits (0.116" diameter), ensuring accurate pilot holes and reduced material stress.
• Compliance with environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industrial sectors.

Professional Applications & Engineering Value

This No. 6-18 thread forming screw is engineered to address common challenges in sheet metal assembly, such as material fatigue and corrosion. The 18-8 stainless steel offers excellent resistance to rust and oxidation, extending service life in demanding conditions. Its thread forming Type A design displaces material to form strong, reliable threads without chips, reducing the risk of loosening under vibration. The fully threaded configuration and pointed tip facilitate easy starting and deep penetration, while the Phillips flat head ensures a secure, flush fit that minimizes protrusions. Ideal for HVAC, electronics enclosures, and automotive panels, this screw enhances structural integrity and assembly speed, making it a top choice for industrial tapping screw applications.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a thread diameter of 0.138" and approximately 18 threads per inch, ensuring precise fits. It features a fully threaded shank and is designed for use with a No. 32 drill bit (0.116" diameter) in materials up to 0.025" thickness. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming it meets strict environmental and safety regulations for industrial fasteners.
