S-97975A325 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel material, ensuring long-term reliability in various environments without rust or degradation.
• Efficient installation in plastic materials due to the DST thread forming design, which creates strong, secure threads without pre-tapping and reduces assembly time.
• Enhanced driving control and reduced cam-out with the Phillips drive and No. 2 drive size, providing consistent torque application and minimizing tool slippage.
• Optimized thread engagement and holding power from the fully threaded design and 18 TPI, delivering uniform stress distribution and vibration resistance in plastic assemblies.
• Minimized material cracking or damage thanks to the blunt tip, which gently displaces plastic during insertion for reliable fastening in delicate applications.
• Broad compatibility and ease of use with a standard No. 29 drill bit size (0.136" diameter), simplifying hole preparation and ensuring precise fits.
• Compliance with environmental and safety standards including RoHS 3 and REACH, making these screws suitable for regulated industries and global supply chains.

Professional Applications & Engineering Value

These No. 8 x 5/8" 410 Stainless Steel DST thread forming screws are engineered to address common challenges in plastic assembly, such as material stress, thread stripping, and corrosion. The thread forming tapping method eliminates the need for pre-threaded holes, reducing labor and tooling costs while providing high pull-out strength. Made from 410 Stainless Steel, they offer excellent durability and resistance to oxidation, ideal for outdoor or humid conditions. The Phillips drive ensures straightforward installation with standard tools, and the fully threaded design maximizes grip in various plastic thicknesses. Commonly used in electronics enclosures, automotive components, and consumer goods, these screws help prevent cracking and ensure long-term performance in plastic fastening applications.
