Professional Applications & Engineering Value
Engineered for demanding industrial applications, these zinc-plated steel truss head screws address critical fastening challenges where vibration resistance and surface protection are paramount. The wide truss head design distributes clamping force over a larger area, preventing damage to softer materials while maintaining secure fastening. With UNC coarse threads and Class 2A thread fit, installation is streamlined while maintaining precise tolerances for heavy-duty assembly operations. The combination of 60,000 psi tensile strength and Rockwell B69 hardness ensures these slotted drive screws withstand substantial mechanical stress in machinery, electrical enclosures, and structural applications where reliability cannot be compromised.
Specification Summary & Compliance
This 1/4"-20 x 1" fully threaded screw features precise Class 2A thread fit per UNC standards with coarse thread spacing for optimal performance. Manufacturing complies with ASME B18.6.3 specifications ensuring dimensional accuracy and interchangeability. The product is RoHS 3 (2015/863/EU) compliant and meets REACH (EC 1907/2006) requirements for environmental and safety standards, making it suitable for global industrial applications requiring regulatory compliance.
