Professional Applications & Engineering Value

This flanged socket head cap screw delivers critical engineering advantages in demanding applications where corrosion resistance and structural integrity are paramount. Manufactured from 18-8 stainless steel, it effectively combats rust and chemical degradation in manufacturing equipment, marine hardware, and food processing machinery. The 1/2"-13 UNC coarse thread with Class 3A fit ensures rapid assembly and superior vibration resistance, while the integrated flange provides increased bearing surface to prevent joint loosening under dynamic loads. With 80,000 PSI tensile strength and Rockwell B83 hardness, this fastener maintains clamping force in high-stress environments, making it an optimal choice for machinery frames, structural assemblies, and heavy equipment where reliability cannot be compromised.

Specification Summary & Compliance

This inch-system fastener features 1/2"-13 UNC coarse threads with precision Class 3A thread fit for consistent engagement. The partially threaded design provides a 3/4" threaded section and 1-1/2" grip length within the overall 2-1/4" length. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for industrial applications worldwide.
