Professional Applications & Engineering Value
These 1/4"-20 UNC flat head screws in 18-8 Stainless Steel are engineered to address common industrial challenges such as corrosion, vibration, and assembly efficiency. The passivated finish enhances the innate corrosion resistance of stainless steel, making these screws ideal for applications in marine, chemical processing, and outdoor equipment where moisture and chemicals are prevalent. The hex drive and coarse UNC threads facilitate quick, secure installation in metals, plastics, and wood, reducing assembly time while maintaining high tensile strength. This combination of durability and precision threading ensures reliable performance in machinery, automotive, and structural assemblies, minimizing maintenance and downtime.
Specification Summary & Compliance
This product features a 1/4"-20 UNC thread with Class 3A fit for high precision, a length of 1/2", and full threading. It complies with Fed. Spec. QQ-P-35 (referencing MS24671-28) for quality assurance, and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use in global markets.
