S-92400A110 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding environments.
• Excellent thread retention in plastic due to the TRS thread forming design, reducing the risk of loosening and stripping.
• High torque transmission and easy installation provided by the external hex head and Tri-Lobe shank cross-section.
• Reliable fastening in pre-drilled holes using a standard No. 44 drill bit (0.086" diameter) for precise, secure assemblies.
• Full-length threading ensures maximum grip and uniform stress distribution along the entire 1/4" length.
• Enhanced material displacement control with a blunt tip, minimizing cracking in plastic substrates during installation.
• Compliance with major environmental regulations including RoHS 3 and REACH, ensuring safe and sustainable use.

Professional Applications & Engineering Value

Engineered for high-performance fastening in plastic assemblies, this No. 4 TRS tapping screw utilizes thread forming technology to create strong, permanent threads without cutting away material. The Tri-Lobe shank design and zinc-plated steel construction provide exceptional resistance to vibration and corrosion, addressing common failure points in automotive trim, electronic enclosures, and consumer goods. Its external hex drive and blunt tip ensure quick, controlled installation with reduced risk of plastic fracture, making it an ideal plastic fastener for automated or manual assembly lines seeking reliability and efficiency.
