S-99512A652 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with Black-Oxide Steel coating, ideal for industrial environments and extending service life.
• Enhanced torque transmission and reduced cam-out thanks to the T8 Torx drive, ensuring secure and efficient installation.
• Reliable, high-strength threads in plastic achieved through the TRS thread forming design, minimizing stress and preventing material cracking.
• Secure, vibration-resistant fastening from the Tri-Lobe shank cross-section, which creates a tight, lasting hold in plastic substrates.
• Optimized for quick, precise installation with a blunt tip and fully threaded 1/4" length, reducing assembly time and improving alignment.
• Consistent performance and interchangeability ensured by the precise 28 TPI thread pitch and standard pan head design.
• Compliance with global environmental standards including RoHS 3 and REACH, making them suitable for regulated markets and sustainable manufacturing.

Professional Applications & Engineering Value

These No. 2 Black-Oxide Steel Tapping Screws are engineered to address common challenges in plastic assembly, such as material stress and thread stripping. The TRS thread forming method and Tri-Lobe shank design displace plastic material without cutting, creating strong, load-bearing threads that resist loosening under vibration. The T8 Torx drive provides superior torque transfer, reducing the risk of driver slippage and head damage during high-volume installation. Ideal for plastic applications in electronics, automotive components, and consumer goods, these screws ensure durable, reliable fastening while the Black-Oxide finish offers added protection against corrosion in varied operating conditions.
