Overview
This heavy-duty hex nut is engineered for critical structural and machinery assembly applications requiring superior clamping force and vibration resistance. Manufactured from high-grade carbon steel and heat-treated to achieve a Grade 10 property class, it delivers exceptional tensile strength and reliable performance under sustained loads. The nut conforms to the DIN 6923 standard, which specifies dimensional tolerances and mechanical properties for hex nuts with a washer face, ensuring a precise and stable fit against mating surfaces. The black oxide finish provides a layer of protection against corrosion in indoor or controlled environments. Sold in a convenient pack of 25, it is an essential component for maintenance, construction, and manufacturing operations.
