S-99512A667 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior torque transmission with T15 Torx drive prevents cam-out and ensures secure fastening in plastic assemblies
• Exceptional thread retention through TRS thread forming design creates permanent, vibration-resistant threads in plastic materials
• Enhanced corrosion resistance with Black-Oxide Steel finish provides durable protection in various environmental conditions
• Maximum holding power achieved through Tri-Lobe shank design that displaces material for superior pull-out resistance
• Optimized for plastic applications with blunt tip and right-hand threading for clean installation without material cracking
• Precision compatibility with standard 1/8" drill bits simplifies installation and reduces preparation time
• Reliable performance with fully threaded design ensures consistent fastening strength along the entire screw length

Professional Applications & Engineering Value

These No. 6 x 3/4" TRS plastic tapping screws are specifically engineered to address common challenges in plastic assembly applications. The thread forming design eliminates the need for pre-tapped holes while creating strong, permanent threads that resist loosening under vibration and thermal cycling. The T15 Torx drive system provides superior torque transmission compared to traditional drive types, reducing installation time and preventing damage to screw heads. Manufactured from Black-Oxide Steel, these fasteners offer enhanced corrosion resistance ideal for electronics enclosures, automotive plastic components, and consumer products where reliability and aesthetics are paramount. The Tri-Lobe shank cross-section and blunt tip design prevent plastic material stress cracking during installation, making them perfect for brittle plastic materials commonly used in industrial applications.

Specification Summary & Compliance

These precision-engineered tapping screws feature a 0.138" thread diameter with 19 threads per inch and standard Class 2A thread tolerances for consistent performance. The TRS (Thread Rolling Screw) design follows industry-standard thread forming specifications for plastic materials. All components are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the latest international standards for hazardous substance restrictions and chemical safety in industrial applications.
