S-90585A031 10-24 x 2" ASME B18.3 Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction and passivated finish, ideal for harsh chemical and marine environments
• Exceptional mechanical strength delivering 70,000 psi tensile strength and Rockwell B55 hardness for reliable load-bearing performance
• Precision Class 3A thread fit ensures secure fastening with minimal backlash in high-vibration applications
• Full threading along 2" length provides maximum grip depth and adjustment flexibility in assembled components
• Hex drive design with 1/8" drive size enables high-torque installation without cam-out risks
• Standard 82° countersink angle allows flush mounting in precision-machined surfaces
• Compliance with major industrial standards including ASME B18.3 for dimensional consistency

Professional Applications & Engineering Value

These 10-24 UNC flat head screws solve critical challenges in industrial applications where corrosion resistance and mechanical reliability are paramount. The 316 stainless steel composition combined with passivated surface treatment creates a protective barrier against chlorides and acidic environments, making these hex drive screws ideal for chemical processing equipment, marine hardware, and food processing machinery. The coarse UNC thread profile with Class 3A fit maintains secure connections in high-vibration settings while the fully threaded design along the entire 2" length ensures maximum engagement in thick materials. Engineering teams specify these flat head fasteners for applications requiring flush mounting without compromising on 70,000 psi tensile strength or regulatory compliance.
