S-99512A668 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastics through the Tri-Lobe shank design that displaces material to create durable, vibration-resistant threads
• Enhanced corrosion resistance with black-oxide steel construction, ideal for industrial environments and extended service life
• High-torque driving capability with the T15 Torx drive system, reducing cam-out and tool wear for efficient assembly
• Optimized for plastic applications using thread-forming (TRS) technology that eliminates chips and prevents material stress cracking
• Full-length threading ensures maximum engagement and pull-out strength across the entire 1" length
• Secure regulatory compliance meeting RoHS 3 and REACH standards for safe use in regulated industries
• Precise 19 TPI thread pitch provides reliable fastening in various plastic densities without stripping

Professional Applications & Engineering Value

These No. 6 plastic tapping screws deliver exceptional engineering value for plastic assembly applications where material integrity is paramount. The thread-forming TRS design with Tri-Lobe shank cross-section creates strong, permanent threads in plastic substrates without generating chips or debris that could compromise electronic components. The black-oxide steel construction provides sufficient corrosion protection for indoor industrial environments while maintaining the high tensile strength needed for durable fastening. The T15 Torx drive system enables higher torque application than Phillips or slotted drives, preventing fastener damage during installation in automated assembly processes. These screws are particularly valuable in plastic fabrication, electronics enclosures, automotive trim, and appliance manufacturing where vibration resistance and long-term reliability are critical performance requirements.

Specification Summary & Compliance

These fully threaded screws feature a No. 6 size with 0.138" thread diameter and 19 TPI thread pitch, designed with right-hand thread direction and blunt tip for optimal performance in plastic materials. The pan head style with standard rounded profile provides a low-profile finish with 0.27" head diameter. Manufactured to precise dimensional standards with Class 2A thread tolerances, these screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring they meet current environmental and safety standards for industrial applications.
