S-92400A430 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Exceptional holding power in plastic materials due to the advanced tri-lobe shank design that creates secure, vibration-resistant threads
• High-torque installation capability with external hex drive head for reliable fastening and easy removal when needed
• Reduced installation stress through thread forming technology that displaces material without cutting or creating chips
• Full-length fastening engagement with completely threaded blunt tip design for consistent clamping force along the entire length
• Wide bearing surface distribution from the 0.52" flange diameter for enhanced load distribution and material protection
• Environmental compliance assurance meeting RoHS 3 and REACH standards for responsible manufacturing and global acceptance

Professional Applications & Engineering Value

These 1/4"-10 zinc-plated steel TRS tapping screws deliver exceptional engineering value for plastic fastening applications where reliability is critical. The thread forming design eliminates the weakness of cut threads by cold-forming mating threads in plastic substrates, creating stronger connections that resist loosening under vibration. The tri-lobe shank cross-section generates necessary interference while minimizing stress concentration, preventing material cracking in brittle plastics. With zinc-plated corrosion protection, these hex head screws maintain integrity in humid or mildly corrosive industrial environments. The fully threaded blunt tip ensures maximum thread engagement for superior pull-out resistance, making them ideal for plastic assembly in automotive components, electrical enclosures, and consumer products where durable fastening is essential.

Specification Summary & Compliance

This tapping screw features precise 1/4"-10 thread configuration with right-hand thread direction and TRS (Thread Rolling Screw) design for optimal performance in plastic materials. The screw maintains dimensional accuracy with 5/8" length, 3/8" head width, and 0.52" flange diameter for consistent installation. Manufactured to work with 5.5mm drill bit size (0.2165"), this fastener demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring regulatory acceptance for industrial applications worldwide.
