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.
- Exceptional mechanical strength offering 80,000 psi tensile strength and Rockwell B80 hardness for heavy-duty, high-stress applications.
- Reliable coarse UNC threading with Class 2A fit for quick, secure installation and reduced risk of cross-threading.
- Optimized flush mounting thanks to the standard flat head profile and 82° countersink angle, providing a smooth, unobtrusive finish.
- Durable slotted drive design for straightforward installation using common tools, minimizing assembly time.
- Partial threading allows for precise clamping force control, ideal for materials requiring specific grip lengths.
- Full regulatory compliance with ASME B18.6.3, RoHS 3, and REACH, ensuring safety and environmental standards are met.
Professional Applications & Engineering Value
Engineered for demanding industrial environments, these 10-24 UNC flat head screws in 18-8 Stainless Steel provide a robust fastening solution where corrosion resistance and high tensile strength are critical. The passivated finish enhances durability against chemicals and moisture, making them ideal for machinery, automotive assemblies, and outdoor equipment. The coarse thread design ensures rapid installation and secure holding power in soft materials or where vibration resistance is needed. With a 2 1/2" length and partial threading, they offer flexibility in applications requiring specific unthreaded shank sections, reducing the risk of material damage while maintaining consistent Class 2A thread fit for precision assembly.
Specification Summary & Compliance
This screw adheres to ASME B18.6.3 specifications, with precise Class 2A thread fit and UNC coarse threading for consistent performance. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Dimensions include a 10-24 thread size, 2 1/2" length, and 82° countersink angle, manufactured to exact tolerances for reliable industrial use.
