S-90410A240 10-24 x 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Self-tapping efficiency with F-type thread cutting design eliminates pre-tapping needs, reducing installation time and labor costs in brass, cast iron, and sheet metal.
• Exceptional corrosion resistance from 410 stainless steel construction ensures long-term reliability in demanding industrial environments.
• Optimized drive engagement with No. 2 Phillips drive provides secure torque transmission and reduces cam-out risks during high-speed assembly.
• Full-threaded shank design maximizes thread contact and pull-out resistance for superior holding power in coarse UNC threading applications.
• Standard pan head profile offers low-profile seating and consistent clamping force distribution across fastened surfaces.
• Precision-engineered dimensions including 0.373" head diameter and 3/8" length ensure compatibility with standard UNC 10-24 threaded holes.
• Regulatory compliance assurance with RoHS 3 and REACH standards meets international environmental and safety requirements for industrial procurement.

Professional Applications & Engineering Value

These 10-24 UNC thread cutting screws deliver critical engineering advantages in metal fabrication and assembly operations. The 410 stainless steel composition provides inherent corrosion resistance that prevents degradation in humid or chemically exposed environments, while the F-type thread cutting geometry creates precise mating threads in ductile materials like brass, cast iron, and sheet metal without requiring separate tapping operations. The Phillips pan head design combines efficient drive engagement with a low-profile installation that clears obstructions in confined spaces. Manufacturers benefit from reduced assembly time and improved joint integrity when securing electrical enclosures, machinery components, and structural metal assemblies where vibration resistance and long-term fastener performance are paramount.

Specification Summary & Compliance

Manufactured to UNC coarse thread standards with Class 2A fit tolerances, these fully threaded screws maintain dimensional accuracy across all critical parameters including 0.19" thread diameter and No. 25 drill bit compatibility. The fasteners conform to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring compliance with international restrictions on hazardous substances for industrial and export applications.
