S-91500A245 10-24 x 3/4" ASME B18.6.3 Stainless Steel Phillips Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments due to 316 stainless steel construction
• High tensile strength of 70,000 psi ensures reliable, long-lasting fastening under load
• Passivated finish enhances surface durability and provides an extra layer of protection against corrosion
• Class 2A thread fit and UNC coarse threading offer easier assembly and reduced risk of cross-threading
• 82° countersink angle and flat head design allow for a flush, secure fit in tapered seats
• Phillips No. 2 drive enables efficient installation with common tools, minimizing slippage
• Full threading along the 3/4" length provides maximum grip and holding power across the entire fastener

Professional Applications & Engineering Value

Engineered for demanding industrial settings, these 10-24 UNC flat head screws in 316 stainless steel excel where corrosion resistance is critical, such as in marine, chemical processing, and food-grade equipment. The passivated finish further boosts durability against oxidants and chlorides, preventing premature failure. Their coarse thread design ensures quick, secure fastening in softer materials or where vibration is a concern, while the 82° countersink provides a clean, flush finish for aesthetic and safety requirements. With a Rockwell B80 hardness and high tensile strength, they maintain integrity under stress, making them a reliable choice for structural assemblies, machinery, and enclosures exposed to harsh conditions.

Specification Summary & Compliance

This flat head screw adheres to ASME B18.6.3 specifications, ensuring dimensional accuracy and performance reliability. Threading conforms to UNC coarse standards with a Class 2A thread fit for consistent engagement. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing it is free of hazardous substances and safe for various industrial applications.
