- Reliable coarse threading with UNC 1 1/4"-7 thread and Class 2A fit ensures easy installation and secure, vibration-resistant connections.
- Optimized partial threading provides enhanced grip and clamping force where full thread engagement isn't required.
- Heavy-duty hex head design (1 7/8" width, 25/32" height) with external drive allows for high-torque application with standard tools.
- Long 9-inch length accommodates thick materials and assemblies, offering versatile fastening solutions.
- Full regulatory compliance with RoHS 3 and REACH standards, ensuring safety and environmental responsibility.
Professional Applications & Engineering Value
This heavy-duty hex head screw is engineered to solve critical fastening challenges in demanding industrial settings. The 18-8 Stainless Steel material provides excellent corrosion resistance, making it suitable for outdoor, marine, and chemical-exposed applications where durability is paramount. The coarse UNC thread and Class 2A fit facilitate quick assembly and reduce the risk of cross-threading, while the partial threading design concentrates clamping force for more secure joints in structural frameworks, machinery, and construction projects. With an 80,000 psi tensile strength and external hex drive, it withstands extreme vibrations and loads, ensuring long-term reliability in heavy equipment, transportation, and infrastructure applications.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent dimensional accuracy and ease of assembly. It is manufactured in the inch system with a thread size of 1 1/4"-7, a minimum thread length of 3 inches, and a total length of 9 inches. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets strict environmental and safety standards for industrial use.
