S-91773A249 10-24 x 1 1/4" ASME B18.6.3 Stainless Steel Round Head Phillips Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ensuring long-term reliability in harsh environments.
• High tensile strength of 100,000 psi provides exceptional load-bearing capacity and resistance to mechanical failure.
• Rockwell B100 hardness offers excellent durability and wear resistance for repeated use in demanding applications.
• Coarse UNC threads with Class 2A fit enable quick, secure installation and reliable fastening in various materials.
• Fully threaded design ensures consistent grip and maximum holding power along the entire screw length.
• Phillips drive (No. 2 size) allows for efficient, controlled driving with standard tools, reducing installation time.
• Rounded head profile provides a smooth, finished appearance while minimizing snagging in assembled products.

Professional Applications & Engineering Value

These 10-24 UNC rounded head Phillips screws are engineered to address critical industrial fastening challenges where corrosion resistance and high tensile strength are paramount. The 18-8 stainless steel material, combined with a passivated finish, effectively resists oxidation and chemical exposure in marine, food processing, and outdoor equipment applications. The coarse thread design ensures reliable performance in softer materials or where vibration resistance is needed, while the fully threaded construction provides uniform stress distribution. These screws deliver consistent performance in assembly lines, machinery maintenance, and structural frameworks where ASME B18.6.3 compliance is required for quality assurance and interoperability.
