S-92400A330 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic thanks to the Tri-Lobe shank design that displaces material to create permanent, vibration-resistant threads
• Corrosion-resistant durability provided by the zinc-plated steel construction, ensuring long-term reliability in various environments
• Effortless installation and high torque capability with the external hex drive, allowing for quick assembly with standard tools
• Reduced risk of material cracking or stress due to the thread forming (TRS) tapping method, which forms threads without cutting and removing material
• Consistent, full-length fastening engagement with fully threaded design, providing uniform clamping force along the entire 1" length
• Secure environmental compliance meeting RoHS 3 and REACH standards, making them safe for regulated industries and applications
• Optimized for plastic assemblies with a blunt tip and specific No. 21 drill bit size (0.159"), ensuring precise fit and preventing damage during installation

Professional Applications & Engineering Value

These No. 10-14 x 1" zinc-plated steel TRS tapping screws are engineered to solve common fastening challenges in plastic assemblies. The thread forming technology and Tri-Lobe shank work in tandem to cold-form strong, clean threads in plastic materials, eliminating chips and providing exceptional resistance to loosening under vibration—a critical advantage in automotive, electronics, and appliance manufacturing. The zinc-plated steel offers a protective barrier against corrosion, extending the life of products exposed to humidity or harsh conditions. With an external hex drive for high-torque applications and a blunt tip that aligns easily without piercing through thin plastic walls, these screws streamline production, reduce assembly errors, and enhance the structural integrity of plastic components.

Specification Summary & Compliance

This No. 10-14 x 1" plastic tapping screw features a 0.19" thread diameter with 14 threads per inch and is fully threaded for maximum grip. It adheres to standard inch measurements with a hex head (0.312" width, 0.151" height) and 0.414" flange diameter for increased bearing surface. Manufactured as a thread forming (TRS) screw with a right-hand thread direction, it is designed for use with a No. 21 drill bit (0.159" diameter). The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it meets stringent environmental and safety regulations for hazardous substances.
