S-90380A014 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention with tri-lobe shank design that creates secure, vibration-resistant threads in plastic materials
• Corrosion-resistant zinc plating provides durable protection against environmental elements in industrial settings
• Efficient thread forming technology eliminates the need for tapping operations, reducing assembly time and labor costs
• Optimal drive engagement with Phillips No. 1 drive style prevents cam-out and ensures consistent torque application
• Full threading along 1/2" length delivers maximum holding power and uniform stress distribution
• Standard pan head design offers excellent bearing surface for reliable clamping force in plastic assemblies
• Precision-engineered dimensions with 0.086" thread diameter and 28 TPI ensure perfect fit with No. 47 drill bit (0.0785")

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are specifically engineered for plastic fastening applications where traditional threaded fasteners would fail. The thread forming technology and tri-lobe shank cross-section create strong, permanent threads in plastic materials without causing stress cracking or material failure. This design eliminates the need for separate tapping operations, significantly reducing assembly time in high-volume manufacturing environments. The Phillips drive system with No. 1 size provides reliable torque transmission while the fully threaded design ensures maximum pull-out resistance in thermoplastic and thermoset applications. These tapping screws are ideal for electronics enclosures, automotive plastic components, and consumer product assemblies where vibration resistance and long-term reliability are critical.

Specification Summary & Compliance

These No. 2 x 1/2" TRS tapping screws feature precision thread dimensions with 0.086" thread diameter and 28 threads per inch, designed to work with No. 47 drill bit (0.0785" diameter). The thread forming design creates secure fastening in plastic materials without pre-tapped holes. Manufactured from zinc-plated steel with standard pan head profile and Phillips No. 1 drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global markets and environmentally sensitive applications.
