S-95893A623 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability
• High-torque installation capability via Torx T8 drive, reducing cam-out and tool wear for efficient assembly
• Secure, vibration-resistant fastening in plastics due to the Tri-Lobe shank design that forms strong, lasting threads
• Flush, low-profile installation with standard flat head and 82° countersink angle for smooth, finished surfaces
• Full-length threading ensures maximum grip and uniform stress distribution along the entire fastener length
• Simplified installation process with pre-specified No. 44 drill bit size, reducing errors and improving workflow
• Compliance with global environmental standards including RoHS 3 and REACH, ensuring safe and sustainable use

Professional Applications & Engineering Value

This No. 4-20 TRS plastic tapping screw is engineered to address common challenges in plastic assembly, such as material cracking and thread stripping. The thread forming Tri-Lobe shank displaces plastic material without cutting, creating robust, high-strength threads that resist loosening under vibration. Made from 18-8 stainless steel, it offers excellent corrosion resistance, making it suitable for outdoor, marine, or chemically exposed applications. The Torx T8 drive enables higher torque application compared to Phillips or slotted drives, reducing assembly time and improving fastener integrity. Ideal for electronics enclosures, automotive trim, and consumer products, this screw ensures reliable performance in plastic fastening where durability and precision are critical.

Specification Summary & Compliance

This thread forming screw adheres to inch system specifications: No. 4-20 thread size with 20 threads per inch, 3/4" length, and right-hand threading. The flat head features an 82° countersink angle for standard flush mounting. Manufactured to precise dimensional tolerances, it is designed for use with a No. 44 drill bit (0.086" diameter). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
