Overview
This heavy-duty hex nut is engineered for critical bolted connections where failure is not an option. Manufactured from high-grade 30CrMo alloy steel and heat-treated to achieve a Grade 10 property class, it delivers exceptional tensile strength and reliable performance in high-stress, high-vibration environments. The black oxide finish offers a baseline of corrosion protection and a clean, professional appearance. Supplied in a convenient pack of 25, this nut is a fundamental component for industrial assembly, construction, and heavy machinery maintenance.
