S-90380A262 Length 7/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention with tri-lobe shank design that creates strong, vibration-resistant threads in plastic materials
• Corrosion-resistant zinc plating provides durable protection against environmental elements in industrial applications
• Efficient thread forming action eliminates the need for pre-tapped holes, reducing assembly time and labor costs
• Precise Phillips No. 1 drive compatibility ensures secure tool engagement and reduces cam-out during installation
• Optimized 28 TPI threading delivers maximum holding power in plastic substrates with minimal material stress
• Full threading along 7/16" length provides consistent fastening strength throughout the entire engagement area
• Compliance with international standards meets RoHS 3 and REACH requirements for global manufacturing operations

Professional Applications & Engineering Value

These No. 2 zinc-plated steel TRS tapping screws are specifically engineered for plastic assembly applications where traditional fastening methods often fail. The thread forming design with tri-lobe shank cross-section displaces plastic material rather than cutting it, creating zero clearance threads that resist loosening from vibration and thermal cycling. This thread forming screw technology eliminates the need for separate tapping operations and insert installation, significantly reducing assembly costs while providing superior pull-out strength. The zinc-plated steel construction ensures long-term corrosion resistance in demanding environments, while the Phillips drive system offers reliable installation torque control. These screws are precision-matched to 5/64" drill bits for optimal hole preparation in various plastic materials, from thermoplastics to composite assemblies.

Specification Summary & Compliance

These thread forming screws feature a 0.086" thread diameter with 28 TPI precision threading and 7/16" length for consistent performance in plastic substrates. The TRS (Thread Rolling Screw) design follows industry-standard thread forming principles with Class 2A thread tolerances for reliable engagement. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for international supply chains. The pan head style with 0.167" head diameter provides optimal clamping force distribution without sinking into plastic surfaces.
