Professional Applications & Engineering Value
Engineered for demanding industrial applications, these 1/4"-20 UNC hex head screws deliver critical performance where corrosion resistance and structural integrity are paramount. The 18-8 stainless steel composition prevents degradation in moisture-rich or chemical-exposed environments, while the coarse thread design provides superior holding power in softer materials and faster installation cycles. With partial threading and Class 2A thread fit, these fasteners eliminate unnecessary thread engagement points, reducing stress concentration and preventing material damage in assembly-critical components like machinery frames, structural supports, and equipment housings. Their 80,000 psi tensile strength ensures long-term reliability in high-vibration settings, making them ideal for manufacturing, construction, and heavy equipment maintenance.
Specification Summary & Compliance
This 1/4"-20 UNC hex head screw features precise Class 2A thread fit per ASME/ANSI standards, ensuring dimensional accuracy and interchangeability. The partially threaded configuration with 3/4" minimum thread length provides controlled engagement depth. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, guaranteeing safe usage across global markets. The external hex drive and right-hand thread orientation maintain industry-standard installation practices.
