S-90417A123 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior thread forming capability with TRS design creates permanent, vibration-resistant threads in plastic materials without chips or debris
• Enhanced corrosion resistance from Black-Oxide Steel finish provides durable protection in various industrial environments
• Maximum torque transmission through No. 2 Phillips drive prevents cam-out and ensures secure installation
• Optimized plastic fastening with Tri-Lobe shank design reduces installation torque while increasing pull-out resistance
• Full 1/4" thread engagement delivers consistent holding power across the entire screw length for reliable plastic assembly
• Precision thread geometry with 19 TPI ensures smooth installation and superior thread retention in plastic substrates
• Industry compliance assurance meeting RoHS 3 and REACH regulations for global manufacturing applications

Professional Applications & Engineering Value

These TRS thread forming screws are specifically engineered for plastic fastening applications where traditional fasteners fail. The Tri-Lobe shank cross-section and thread forming design displace plastic material rather than cutting it, creating zero clearance threads that significantly reduce stress cracking in brittle plastics. The Black-Oxide Steel construction provides essential corrosion protection while maintaining the dimensional stability required for precision plastic assemblies. With 0.138" thread diameter and 19 TPI thread pitch, these screws deliver optimal performance in thermoplastics and other plastic substrates, solving common issues of strip-out, vibration loosening, and material failure in automotive, electronics, and consumer product manufacturing.

Specification Summary & Compliance

This No. 6 TRS tapping screw features a 0.138" thread diameter with 19 threads per inch and 1/4" fully threaded length. Manufactured from Black-Oxide Steel with standard thread forming specifications for plastic applications. The screw is designed for use with 1/8" drill bit size (0.125" diameter) and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring restricted substance compliance.
