Professional Applications & Engineering Value
Engineered for industrial machinery, electronic enclosures, and automotive assemblies, this 1/4-20 UNC truss head screw solves critical fastening challenges. The 18-8 stainless steel material combined with passivated finish provides exceptional resistance to corrosion and chemical exposure, extending service life in demanding conditions. The unique low profile rounded head distributes clamping force over a wider area (0.755" diameter), preventing surface damage to softer materials while maintaining a streamlined appearance. With fully threaded coarse pitch design and Class 2A thread fit, these screws ensure rapid installation and reliable performance in vibration-prone applications where maintenance access may be limited.
Specification Summary & Compliance
This truss head screw features precise 1/4"-20 UNC coarse threads with Class 2A thread fit per inch-system standards. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial applications. Dimensions include 0.755" head diameter, 1/2" length, and low-profile truss head design with slotted drive configuration.
