Professional Applications & Engineering Value
These black oxide steel screws deliver exceptional engineering value in industrial assembly where corrosion resistance and high tensile strength are critical. The fully threaded UNC coarse pattern ensures rapid installation and superior pull-out resistance in metal fabrication, machinery, and equipment manufacturing. The Phillips No. 3 drive provides reliable torque transmission while the rounded pan head design offers a low-profile finish that won't snag on components. With Class 2A thread fit precision, these screws maintain consistent clamping force in vibration-prone applications, making them ideal for automotive, construction, and heavy equipment assemblies requiring durable fastening solutions.
Specification Summary & Compliance
This 1/4"-20 x 3/4" screw features Class 2A thread fit tolerances with UNC coarse threading and complies with ASME B18.6.3 manufacturing specifications. The product meets RoHS 3 (2015/863/EU) compliance standards and is REACH (EC 1907/2006) compliant for hazardous substance restrictions. Manufacturing controls ensure dimensional accuracy across all critical parameters including 0.492" head diameter and fully threaded design for consistent performance in industrial applications.
