Professional Applications & Engineering Value
This black-oxide steel hex nut is engineered to address critical challenges in industrial assembly and heavy machinery. The M14 x 1.25mm extra fine metric thread delivers enhanced sealing capability, preventing fluid or gas leakage in hydraulic systems and pressurized equipment. Its Class 8 strength grade withstands high tensile and shear stresses, making it ideal for structural frameworks, automotive components, and conveyor systems where vibration resistance is paramount. The black-oxide surface treatment provides a durable barrier against rust and chemical exposure, reducing maintenance frequency in corrosive environments like marine or outdoor installations. Compliant with DIN 934 standards, it ensures seamless integration with other metric fasteners, streamlining procurement and assembly processes for engineers and OEMs.
Specification Summary & Compliance
This hex nut features M14 x 1.25mm extra fine metric threading with a Class 6H thread fit per ISO standards, ensuring precise tolerance and reliable engagement. Manufactured to DIN 934 specifications, it maintains consistent dimensions of 22mm width and 11mm height. The fastener is fully compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) directives, confirming adherence to environmental and safety requirements for industrial use.
