S-90380A245 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the thread-forming Tri-Lobe shank design that creates strong, reliable threads without pre-tapping
• Enhanced corrosion resistance provided by zinc-plated steel construction, extending service life in various industrial environments
• Efficient installation and reduced cam-out with Phillips No. 2 drive that ensures secure tool engagement and consistent torque application
• Maximum thread engagement through fully threaded design, distributing load evenly along the entire fastener length
• Optimized for plastic applications with blunt tip and specific thread geometry that prevents material cracking and splitting
• Simplified assembly process using standard No. 15 drill bit (0.18" diameter) for precise hole preparation and secure fastening
• Reliable performance in demanding applications with 14 threads per inch providing excellent pull-out resistance in plastic substrates

Professional Applications & Engineering Value

These No. 10 x 5/8" zinc-plated steel TRS tapping screws are specifically engineered to address common challenges in plastic assembly applications. The thread-forming Tri-Lobe shank design eliminates the need for pre-tapped holes while creating strong, permanent threads in plastic materials. This innovative approach prevents material stress concentration that often leads to cracking in brittle plastics. The Phillips drive system ensures consistent installation torque, reducing the risk of overtightening that can compromise plastic integrity. With full threading along the 5/8" length, these screws distribute clamping forces evenly, providing superior resistance to vibration loosening in automotive components, electronic enclosures, and consumer products. The combination of zinc-plated steel construction and optimized thread geometry delivers reliable performance in industrial environments where moisture and chemical exposure are concerns.
