S-90417A139 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior thread retention in plastics thanks to the TRS thread forming design that creates strong, permanent threads without chipping or cracking materials
• Enhanced corrosion resistance provided by the Black-Oxide Steel finish, ensuring long-term reliability in various environmental conditions
• Reduced cam-out and improved torque transfer with the Phillips No. 2 drive system, allowing for efficient installation with standard tools
• Excellent pull-out resistance achieved through the Tri-Lobe shank cross-section that displaces material to form secure locking threads
• Minimized material stress during installation with the blunt tip design that gradually forms threads without excessive pressure
• Full-length threading provides consistent holding power along the entire fastener length for maximum engagement in plastic applications
• Environmental compliance assurance with RoHS 3 and REACH standards, making them suitable for regulated industries and global supply chains

Professional Applications & Engineering Value

These No. 10 TRS tapping screws deliver exceptional engineering value in plastic assembly applications where traditional fastening methods often fail. The thread forming action of the Tri-Lobe shank design creates permanent, high-strength threads in plastic materials without generating chips or creating stress concentrations that lead to cracking. The Black-Oxide Steel construction provides essential corrosion protection while maintaining the mechanical properties needed for repeated installation cycles. Engineered specifically for plastic fastening, these screws eliminate the need for inserts or additional components, reducing assembly time and total cost. The combination of 14 TPI thread pitch and 0.19" thread diameter ensures optimal material engagement in various plastic densities, from soft thermoplastics to reinforced composites.

Specification Summary & Compliance

These thread forming screws feature precision No. 10 screw size with 3/4" length and fully threaded design. The TRS tapping screw type utilizes a right-hand thread direction with 14 approximate threads per inch for optimal performance in plastic materials. Manufactured to exacting standards, these fasteners are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet the strictest international requirements for hazardous substance restrictions.
