Key Features & Benefits at a Glance
- Exceptional corrosion resistance from 17-4 PH Stainless Steel, ideal for harsh industrial environments and outdoor applications.
- Superior mechanical strength with 130,000 psi tensile and 105,000 psi yield strength for reliable performance under high-stress conditions.
- Optimized for efficient assembly with a coarse UNC thread and Class 2A fit, ensuring quick installation and reduced risk of cross-threading.
- Durable external hex drive provides a secure grip for high-torque applications, minimizing tool slippage and head stripping.
- Full threading along the 1-1/2" length offers maximum grip and uniform clamping force across the entire fastener.
- Consistent hardness (Rockwell C28) ensures long-term wear resistance and maintains thread integrity through repeated use.
- Compliance with major industry standards including ASME B18.2.1, RoHS 3, and REACH, guaranteeing material safety and regulatory acceptance.
Professional Applications & Engineering Value
This 3/8"-16 UNC Hex Head Screw is engineered from 17-4 PH Stainless Steel to address critical challenges in demanding sectors like heavy machinery, construction, and marine equipment. Its high tensile strength (130,000 psi) and corrosion-resistant properties prevent failure in environments exposed to moisture, chemicals, and stress. The coarse thread design and Class 2A thread fit facilitate rapid installation in tough materials, reducing assembly time while maintaining a secure, vibration-resistant connection. The external hex drive allows for high torque application with standard tools, making it a reliable choice for structural frames, industrial assemblies, and equipment requiring durable, fully threaded fasteners that meet stringent ASME B18.2.1 specifications.
Specification Summary & Compliance
This hex head screw features a 3/8"-16 UNC coarse thread with a Class 2A thread fit, ensuring dimensional accuracy and interchangeability per ASME B18.2.1. It is manufactured from 17-4 PH Stainless Steel (ASTM F593 Grade 630) and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for global industrial use without hazardous substances.
