S-97349A300 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 in plastic assemblies.
• Effortless installation using a No. 2 Phillips drive, reducing tool slippage and speeding up assembly processes.
• Strong, secure fastening through thread forming (DST) technology, which creates durable threads in plastic without pre-tapping.
• Wide compatibility with a pan head design and fully threaded shank, ensuring even pressure distribution and maximum holding power.
• Precise fit and reduced material stress with a blunt tip and standard dimensions (0.164" thread diameter, 18 TPI), minimizing cracking in plastic substrates.
• Streamlined procurement by matching with a No. 29 drill bit (0.136" diameter), simplifying hole preparation and reducing errors.
• Compliance with global standards, including RoHS 3 and REACH, ensuring safe, environmentally responsible use in industrial settings.

Professional Applications & Engineering Value

These No. 8 x 1/2" tapping screws are specifically engineered for plastic applications, where traditional fasteners may cause cracking or stripping. Made from 18-8 stainless steel, they resist rust and corrosion, extending service life in humid or chemical-exposed environments. The thread forming (DST) design displaces material to create strong, permanent threads without chips, reducing assembly time and improving joint integrity. The Phillips pan head offers a low-profile, secure drive, while the fully threaded shank ensures consistent grip across the entire length. Ideal for electronics enclosures, automotive trim, and consumer products, these screws provide reliable performance where vibration resistance and material compatibility are critical.

Specification Summary & Compliance

This product adheres to standard inch measurements with a thread diameter of 0.164" and 18 threads per inch, ensuring precise fits in pre-drilled holes (recommended drill bit size: No. 29). The thread forming tapping method and DST type are optimized for plastic materials. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming the absence of hazardous substances and supporting use in regulated industries.
