Professional Applications & Engineering Value

These 10-24 UNC partially threaded pan head screws deliver critical engineering solutions where corrosion resistance and structural integrity are paramount. The passivated 18-8 stainless steel construction prevents galvanic corrosion and withstands chemical exposure in marine, food processing, and outdoor applications. The partially threaded design provides an unthreaded shoulder that acts as a precision pilot, preventing cross-threading while allowing components to seat firmly against the screw head. With coarse UNC threading and Class 2A thread fit, these fasteners maintain secure connections in high-vibration environments common in machinery, electrical enclosures, and transportation equipment. The combination of 70,000 psi tensile strength and standard pan head profile ensures reliable performance in both structural and non-structural fastening applications across multiple industries.

Specification Summary & Compliance

This 4" length screw features precise Class 2A thread fit with UNC coarse thread spacing (10-24 thread size) and partial threading up to 1½" minimum thread length. Manufactured to ASME B18.6.3 dimensional standards with Rockwell B70 hardness and 70,000 psi tensile strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring unrestricted use in international markets. The passivated surface treatment on 18-8 stainless steel provides enhanced corrosion protection while maintaining the material's inherent strength characteristics.
