S-91770A246 10-24 x 7/8" ASME B18.6.3 Stainless Steel Truss Head Phillips Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with passivated 18-8 stainless steel construction for long-lasting performance in harsh environments
• Enhanced load distribution through the wide truss head design that reduces surface pressure and prevents material damage
• High-strength fastening solution delivering 70,000 psi tensile strength and Rockwell B70 hardness for demanding applications
• Quick installation and removal with Phillips No. 2 drive that provides secure tool engagement and prevents cam-out
• Reliable thread engagement through fully threaded UNC coarse thread design that ensures maximum holding power
• Precision thread fit with Class 2A tolerance for consistent performance and easy assembly in industrial settings
• Broad compatibility with standard 10-24 UNC coarse thread systems commonly used across multiple industries

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 10-24 UNC coarse thread screws with rounded truss heads provide exceptional engineering value in applications where vibration resistance and material integrity are critical. The passivated 18-8 stainless steel construction offers superior corrosion protection, making them ideal for outdoor equipment, marine applications, and chemical processing facilities where exposure to moisture and corrosive elements is common. The unique truss head profile distributes clamping force over a wider surface area than standard flat heads, preventing damage to softer materials while providing a low-profile finish. With fully threaded design and Class 2A thread fit, these fasteners ensure maximum thread engagement and reliable performance in high-vibration machinery, electrical enclosures, and structural assemblies where loosening under dynamic loads is a primary concern.

Specification Summary & Compliance

These industrial-grade fasteners feature precision 10-24 UNC coarse threads with Class 2A thread fit tolerance for consistent performance. Manufactured to ASME B18.6.3 specifications, they ensure dimensional accuracy and interchangeability. The screws maintain full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety. Right-hand threading direction and fully threaded construction provide standardized installation across industrial applications, backed by material certifications for the passivated 18-8 stainless steel composition.
