Professional Applications & Engineering Value
This 18-8 stainless steel socket head cap screw is engineered to address critical challenges in precision assembly and high-stress applications. The combination of a Class 3A thread fit and coarse 1/4"-20 thread ensures rapid installation with minimal risk of stripping, while the passivated finish significantly enhances corrosion resistance in demanding environments such as aerospace, automotive, and heavy machinery. The hex socket drive accommodates high torque tools, providing secure fastening in tight spaces where wrench clearance is limited. Its 80,000 PSI tensile strength makes it suitable for structural components, fixtures, and equipment subjected to dynamic loads, reducing maintenance needs and improving operational reliability.
Specification Summary & Compliance
This socket head cap screw features a 1/4"-20 coarse thread with Class 3A fit for precise tolerance, a partially threaded design with minimum thread length of 1", and meets specifications including MS16995-54, NAS1352C4-24, NASM16995, and Fed. Spec. FF-S-86. It is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations for industrial use.
