S-90380A316 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the tri-lobe shank design that displaces material to create permanent, vibration-resistant threads
• Corrosion-resistant zinc-plated steel construction ensures long-term durability and reliability in various industrial environments
• Efficient Phillips No. 3 drive installation allows for quick, secure fastening with standard tools, reducing assembly time
• Fully threaded design provides maximum grip and pull-out resistance along the entire screw length for secure plastic assemblies
• Precision thread forming action eliminates the need for pre-tapped holes, reducing assembly steps and potential material stress
• Standard pan head profile offers a low-profile finish with good bearing surface for consistent clamping force
• Compliance with major environmental regulations including RoHS 3 and REACH ensures safe, sustainable use in global manufacturing

Professional Applications & Engineering Value

These 1/4"-10 zinc-plated steel TRS thread forming screws are specifically engineered to address common challenges in plastic assembly applications. The unique tri-lobe shank cross-section and thread forming tapping method create strong, permanent threads in plastic materials without causing cracking or stress fractures common with traditional fasteners. This makes them ideal for industrial plastic components requiring vibration resistance and long-term reliability. The fully threaded design ensures maximum engagement in various plastic thicknesses, while the zinc-plated steel construction provides essential corrosion protection for demanding environments. These Phillips drive screws offer reliable performance in automotive plastics, electronic enclosures, and consumer products where material integrity and fastening security are critical.

Specification Summary & Compliance

These TRS tapping screws feature precision 1/4"-10 thread specifications with fully threaded right-hand direction and standard inch measurements. The manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet international standards for hazardous substance restrictions. The thread forming design follows industry standards for plastic fastening applications, providing reliable performance without requiring pre-tapped holes.
