S-91772A254 10-24 x 2 1/4" ASME B18.6.3 Stainless Steel Pan Head Phillips Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with passivated 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Exceptional mechanical strength offering 70,000 psi tensile strength and Rockwell B70 hardness for reliable load-bearing performance in demanding assemblies.
• Optimized thread engagement with UNC coarse threading and Class 2A fit ensures faster installation and reduced cross-threading risks.
• Secure and efficient driving via Phillips No. 2 drive style, providing excellent torque transfer and minimizing cam-out during high-speed assembly.
• Versatile partial threading design allows for precise clamping force control and prevents over-tightening in multi-material applications.
• Regulatory compliance assurance meeting ASME B18.6.3 manufacturing standards while being RoHS 3 and REACH compliant for global supply chain integration.
• Dimensional precision with standardized pan head profile (0.373" diameter) and 2-1/4" length delivering consistent performance in automated assembly systems.

Professional Applications & Engineering Value

Engineered for industrial durability, these 10-24 UNC coarse thread pan head screws solve critical fastening challenges in machinery, electrical enclosures, and structural assemblies. The passivated 18-8 stainless steel construction provides inherent corrosion resistance that withstands chemical exposure and humidity, eliminating premature fastener failure. The partially threaded design creates controlled clamping zones while the coarse UNC threading maintains holding power in soft materials and vibration-prone environments. With Phillips No. 2 drive compatibility, these screws enable rapid installation in high-volume production while the rounded pan head profile distributes bearing stress evenly. These characteristics make them ideal for OEM equipment, marine components, and food processing machinery where corrosion-resistant screws must maintain integrity under continuous operational stress.

Specification Summary & Compliance

Manufactured to ASME B18.6.3 specifications with Class 2A thread fit tolerances ensuring interchangeability.
