Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
- High tensile strength of 80,000 PSI ensures reliable fastening in heavy-duty applications without failure
- Class 2A thread fit provides consistent engagement and easier assembly while maintaining precision tolerances
- External hex drive design allows for high-torque installation with standard tools for efficient assembly operations
- Partially threaded shank enables precise clamping force distribution and prevents joint loosening under vibration
- Coarse UNC threading offers faster installation and reduced cross-threading risk in production environments
- Rockwell B70 hardness maintains thread integrity and prevents stripping during repeated use
Professional Applications & Engineering Value
These 18-8 stainless steel hex head screws deliver exceptional performance in demanding industrial applications where corrosion resistance and mechanical strength are critical. The 1/2"-13 UNC coarse thread configuration provides superior engagement in various materials while the external hex drive enables high-torque installation without cam-out. Engineered with partial threading, these screws concentrate clamping force precisely where needed, preventing joint failure in vibrating machinery, structural frameworks, and heavy equipment assemblies. The combination of 80,000 PSI tensile strength and Rockwell B70 hardness ensures these fasteners maintain integrity under extreme loads, making them ideal for construction, manufacturing, and marine applications where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to exacting ASME B18.2.1 standards with Class 2A thread fit tolerances for consistent performance. These inch system screws feature 1/2"-13 UNC coarse threads with minimum thread length of 1-1/4" and overall length of 2". Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets.
