Professional Applications & Engineering Value
These Grade 5 hex head screws deliver exceptional engineering value in industrial settings where reliability is paramount. The black oxide finish on steel construction provides superior corrosion protection, making them ideal for machinery, equipment assembly, and structural applications exposed to moderate environmental conditions. The UNC coarse threading with Class 2A fit ensures rapid installation and maintains integrity under vibration, while the external hex drive allows for high torque application without stripping. With 120,000 PSI tensile strength and full threading, these industrial screws distribute stress evenly, preventing point failures in critical joints and reducing maintenance frequency across manufacturing, automotive, and construction applications.
Specification Summary & Compliance
This 1/4"-20 hex head screw features precise Class 2A thread fit with UNC coarse threading standards, ensuring dimensional accuracy and compatibility. Manufactured to meet ASME B18.2.1 and SAE J429 specifications for Grade 5 fasteners, it delivers consistent mechanical properties including Rockwell C25 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) environmental regulations, making it suitable for various industrial applications requiring certified components.
