S-92400A180 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic due to the thread-forming Tri-Lobe shank design, which creates strong, reliable threads without pre-tapping.
• Corrosion-resistant zinc-plated steel construction ensures long-term durability and reliability in various industrial environments.
• Easy and secure installation with the 1/4" external hex head, allowing for high torque application and reduced risk of stripping.
• Optimized for plastic materials with a blunt tip and fully threaded design, minimizing material stress and preventing cracking during assembly.
• Precise fit and reduced installation time as it is designed for use with a No. 32 drill bit (0.116" diameter), ensuring accurate pilot holes.
• Compliance with global environmental standards including RoHS 3 and REACH, making it safe for use in regulated industries.
• Consistent performance with 19 threads per inch and right-hand threading, providing reliable fastening in high-vibration applications.

Professional Applications & Engineering Value

This No. 6 zinc-plated steel TRS 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 to create strong, permanent threads, eliminating the need for inserts and reducing assembly costs. Its zinc-plated finish offers excellent corrosion resistance, ideal for electronics enclosures, automotive components, and consumer appliances. The external hex drive ensures quick installation with standard tools, while the blunt tip and precise thread design minimize stress concentration, making it perfect for brittle plastics. This screw provides a reliable, RoHS and REACH compliant solution for high-volume manufacturing in plastic applications.

Specification Summary & Compliance

This screw features a No. 6 size with a 0.138" thread diameter and 19 threads per inch, ensuring precise fit in plastic materials. It is fully threaded with a right-hand thread direction and complies with standard inch measurements. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free from hazardous substances. Designed for use with a No. 32 drill bit (0.116" diameter), it ensures accurate installation and reliable performance in industrial settings.
