- Partial threading design allows for controlled clamping force in specific assembly scenarios
Professional Applications & Engineering Value
These 10-24 Phillips Truss Head Screws deliver critical engineering solutions where corrosion resistance and structural integrity are paramount. The Passivated 18-8 Stainless Steel construction prevents rust and degradation in demanding environments including marine applications, food processing equipment, and outdoor structures. The unique truss head profile provides a larger bearing surface than standard rounded heads, distributing clamp load more effectively across joined materials while maintaining a low-profile appearance. With UNC coarse threading and partial threading design, these screws offer superior pull-out resistance in softer materials and prevent over-tightening in precision assemblies. The combination of 70,000 psi tensile strength and controlled hardness makes these fasteners ideal for vibration-resistant applications where maintaining clamp load is critical to long-term performance.
Specification Summary & Compliance
Manufactured to exacting ASME B18.6.3 specifications with Class 2A thread fit tolerances ensuring precise thread engagement. These 10-24 x 2-1/2" screws feature UNC coarse threading with minimum thread length of 1-1/2" and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The partially threaded design provides controlled fastening characteristics while maintaining the mechanical properties required for industrial applications.
