S-90286A257 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior load distribution with integrated flange design that eliminates the need for separate washers and prevents material pull-through
• Exceptional thread-forming performance creates precise, permanent threads in sheet metal without chip removal for vibration-resistant assemblies
• Optimized for 0.025" maximum drilling thickness when used with No. 21 drill bit (0.159" diameter) for precise installation in thin sheet metal applications
• High-torque installation capability through external hex drive combined with slotted option for versatile driving tool compatibility
• Full 3-inch threading provides maximum engagement length and superior holding power across the entire fastener length
• Environmental compliance assurance with RoHS 3 and REACH regulations for use in regulated industries and international markets
• Right-hand thread direction with 12 threads per inch delivers reliable, standardized fastening performance in sheet metal assemblies

Professional Applications & Engineering Value

This No. 10 hex head tapping screw delivers exceptional value in sheet metal fastening applications where vibration resistance and material integrity are critical. The thread forming technology (Type A) creates strong, permanent threads through material displacement rather than cutting, eliminating metal chips that could cause electrical shorts or contamination in sensitive assemblies. The flanged design with 0.414" diameter provides superior load distribution, reducing stress concentrations and preventing pull-through in thin gauge materials. With fully threaded construction and pointed tip, installation is streamlined while maintaining consistent clamping force across the entire 3-inch length. These engineering features make this external hex drive screw ideal for HVAC systems, electrical enclosures, automotive panels, and industrial equipment where reliable, long-term fastening performance is essential.

Specification Summary & Compliance

This tapping screw features No. 10 size with 0.19" thread diameter and 12 threads per inch in right-hand direction. Manufactured as a Type A thread forming screw with fully threaded shank and pointed tip for optimal sheet metal penetration. The hex head measures 0.313" width with 0.151" height, compatible with standard external hex drivers. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for international markets and regulated industries.
