Professional Applications & Engineering Value
This 1/4"-20 x 6" stainless steel rounded head screw is engineered to address critical challenges in demanding industrial settings. The 18-8 stainless steel material combined with a passivated finish provides excellent resistance to oxidation and chemical exposure, making it suitable for applications in marine, chemical processing, and food equipment where corrosion is a concern. The UNC coarse thread and Class 3A fit ensure a tight, precise connection that withstands vibrational stresses common in machinery and structural assemblies. Its fully threaded design and hex drive facilitate quick, secure fastening in deep or hard-to-reach areas, reducing assembly time and improving overall structural integrity. Ideal for heavy-duty industrial fastening, it delivers reliable performance where high tensile strength and durability are non-negotiable.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with a Class 3A thread fit for high precision and strength. It is manufactured in accordance with ASME B18.3 specifications, ensuring consistent dimensional accuracy. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards.
