S-90380A263 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic due to the thread-forming TRS design and tri-lobe shank, which displaces material to create strong, reliable threads without pre-tapping.
• Enhanced corrosion resistance from the zinc-plated steel construction, ensuring long-term durability in various industrial environments.
• Efficient and reliable installation with the Phillips No. 1 drive, providing good torque transfer and reducing the risk of cam-out during assembly.
• Optimized for plastic fastening with a 5/8" fully threaded length and 28 TPI, delivering maximum thread engagement and pull-out resistance.
• Secure compliance for global markets by meeting RoHS 3 and REACH regulations, ensuring safety and environmental standards are upheld.
• Reduced risk of material splitting thanks to the blunt tip and thread-forming action, which is ideal for softer plastic substrates.
• Consistent performance and interchangeability through standardized inch measurements and right-hand threading, facilitating easy replacement and inventory management.

Professional Applications & Engineering Value

These No. 2 zinc-plated steel TRS tapping screws are specifically engineered for plastic applications, where traditional fasteners may strip or fail. The tri-lobe shank cross-section and thread-forming (TRS) design compress plastic material during installation, creating a tight, vibration-resistant fit that eliminates the need for threaded inserts or adhesives. This is critical in industries like automotive trim, electronics enclosures, and consumer goods assembly, where reliable fastening and material integrity are paramount. The zinc-plated finish provides a protective barrier against oxidation, extending service life in humid or mildly corrosive conditions. By integrating these screws, engineers can achieve faster assembly cycles, reduced component count, and enhanced product longevity in plastic fastening systems.

Specification Summary & Compliance
