S-91858A247 10-24 x 1" ASME B18.6.3 Stainless Steel Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh chemical and marine environments
• Enhanced durability and longevity from passivated surface treatment that increases protection against oxidation
• Reliable fastening performance with 70,000 psi tensile strength and Rockwell B80 hardness for heavy-duty applications
• Quick installation and secure fit thanks to coarse UNC threading and Class 2A thread fit for consistent engagement
• Flush mounting capability with standard 82° countersink angle flat head design for smooth surface finishes
• Broad industrial compliance meeting ASME B18.6.3 specifications and environmental regulations including RoHS 3 and REACH
• Full thread coverage across the entire 1" length provides maximum grip strength in demanding applications

Professional Applications & Engineering Value

These 316 stainless steel flat head screws deliver exceptional value in corrosive environments where standard fasteners fail. The combination of passivated finish and marine-grade stainless steel provides critical protection against saltwater, chemicals, and industrial contaminants that cause premature fastener degradation. With fully threaded 10-24 UNC coarse threading and Class 2A thread fit, these screws offer superior pull-out resistance in soft materials and faster installation in production environments. The 82° countersink angle ensures proper seating in standard chamfered holes, creating flush surfaces essential for machinery, marine hardware, and food processing equipment where protrusions cause operational hazards or cleaning difficulties. These industrial fasteners maintain structural integrity in high-moisture applications while meeting rigorous industry standards.

Specification Summary & Compliance

Manufactured to precise inch system dimensions with Class 2A thread fit tolerance per UNC standards. Complies with ASME B18.6.3 mechanical specifications for flat head screws, ensuring dimensional accuracy and performance reliability. Meets RoHS 3 (2015/863/EU) compliance for restricted hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. Features include 1" length, 10-24 UNC coarse threads, 82° countersink angle, and full threading throughout the shank length.
