Professional Applications & Engineering Value
Engineered for industrial machinery, equipment manufacturing, and structural assemblies, these 12-24 UNC coarse thread hex head screws address critical fastening challenges through their robust material composition and precision threading. The steel construction with zinc plating provides essential protection against environmental corrosion, while the coarse thread profile ensures rapid installation and superior holding power in various substrates. The external hex drive facilitates high-torque applications without stripping, making these fasteners ideal for maintenance operations and production lines where reliability and speed are paramount. With full threading along the 3/4" length, these screws offer maximum engagement depth for secure connections in vibration-prone environments.
Specification Summary & Compliance
These hex head screws feature precision 12-24 UNC coarse threads with Class 2A fit, ensuring proper clearance and consistent performance across industrial applications. Manufacturing adheres to ASME B18.6.3 specifications for dimensional accuracy and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, confirming the absence of restricted substances. The combination of 60,000 PSI tensile strength and Rockwell B69 hardness validates their suitability for high-stress fastening requirements in professional settings.
