S-90286A321 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior sheet metal fastening with thread forming design that creates strong, permanent threads without chips, ensuring reliable connections in thin materials.
• Easy installation and removal thanks to the external hex/slotted drive head combined with a 3/8" hex, providing multiple tool options and high torque capability.
• Enhanced load distribution and vibration resistance from the integrated 0.52" flange, reducing the risk of loosening in dynamic applications.
• Full thread engagement along the 2-1/2" length with a pointed tip for quick starting and precise alignment in pre-drilled 5.5mm holes.
• Durable and compliant construction meeting RoHS 3 and REACH environmental standards, ensuring safe use in regulated industries.
• Optimized for 0.025" maximum drilling thickness with No. 14-10 thread specifications, delivering consistent performance in standard sheet metal assemblies.

Professional Applications & Engineering Value

This No. 14-10 thread forming tapping screw is engineered to address common challenges in sheet metal fabrication, such as material stripping and weak thread retention. The Type A thread forming method displaces metal to form robust internal threads, eliminating chip-related contamination and enhancing joint integrity. With a fully threaded shank and pointed tip, it ensures rapid penetration and secure fastening in pre-drilled holes using a 5.5mm drill bit. The hex head with slotted drive offers versatility for high-torque applications, while the flanged design increases bearing surface to prevent pull-through in thin-gauge metals. Ideal for HVAC, automotive, and electronics enclosures, this screw provides reliable, vibration-resistant performance in demanding environments.

Specification Summary & Compliance

This screw adheres to standard inch measurements with a No. 14 thread diameter (0.242") and 10 threads per inch, ensuring precise fit in sheet metal applications. It features a right-hand thread direction, fully threaded length of 2-1/2", and is designed for use with a 5.5mm (0.2165") drill bit. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), confirming it is free of hazardous substances and suitable for global industrial use.
