S-92400A450 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the unique tri-lobe shank design that creates secure, vibration-resistant threads
• Easy installation and removal with the external hex drive that provides excellent torque transmission and tool engagement
• Corrosion-resistant protection through zinc plating that extends service life in various industrial environments
• Efficient thread forming action that eliminates chip formation and ensures clean, strong threads in plastic substrates
• Full threading along the entire 1" length for maximum grip and uniform stress distribution in plastic assemblies
• Precise installation guidance with recommended 5.5mm drill bit size for optimal performance in plastic applications
• Reliable flange design providing increased bearing surface and preventing over-insertion in plastic components

Professional Applications & Engineering Value

These 1/4"-10 zinc-plated steel TRS thread forming screws are specifically engineered to address common challenges in plastic assembly applications. The tri-lobe shank cross-section creates compressive forces during installation, generating strong, permanent threads in plastic materials without creating chips that could compromise electrical components or contaminate sensitive environments. The external hex drive ensures high torque capability, reducing the risk of cam-out during installation in dense plastics. This combination of thread forming technology and robust zinc-plated steel construction provides exceptional resistance to vibration loosening and pull-out forces, making these screws ideal for automotive plastic components, electronic enclosures, and industrial equipment where reliable fastening in plastic substrates is critical.

Specification Summary & Compliance

These TRS thread forming screws feature precise 1/4"-10 thread pitch with right-hand threading and blunt tip design. Manufactured to exacting dimensional standards with 3/8" hex head width and 0.24" head height for consistent performance. The products are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The fully threaded design and 0.52" flange diameter provide enhanced clamping force distribution in plastic applications.
