Key Features & Benefits at a Glance
- Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh environments and chemical exposure.
- High tensile strength of 70,000 psi ensures reliable load-bearing capacity and structural integrity in demanding applications.
- Excellent durability provided by Rockwell B70 hardness, resisting wear and deformation under stress.
- Secure and efficient installation with an external hex drive and standard 15/16" head width for easy torque application.
- Optimized coarse (UNC) thread design enables faster assembly and reduced risk of cross-threading.
- Precise Class 2A thread fit guarantees consistent engagement and vibration resistance in assembled joints.
- Compliance with major industry standards including ASME B18.2.1, RoHS 3, and REACH for safe, regulated use.
Professional Applications & Engineering Value
This 5/8"-11 UNC hex head screw in 316 Stainless Steel is engineered to address critical challenges in industrial settings, such as corrosion from moisture, chemicals, and saltwater exposure. The partially threaded design provides a non-threaded shank section for precise clamping force, reducing stress concentration and improving joint stability. With its coarse thread and external hex drive, it allows for quick, high-torque installation in heavy machinery, structural steel frameworks, and marine equipment. The combination of 70,000 psi tensile strength and Rockwell B70 hardness ensures long-term performance under dynamic loads, making it a dependable choice for engineers and procurement specialists seeking durable, ASME B18.2.1 compliant fasteners.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit tolerances per UNC standards, with a thread size of 5/8"-11 and a minimum thread length of 1 1/2". It is manufactured in accordance with ASME B18.2.1 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for global industrial use.
