Overview
This Grade 4 carbon steel hex nut is engineered for demanding industrial and construction applications where a high-strength, fine-threaded, and low-profile fastener is required. Its metric M30 thread with a 1.5 mm pitch provides a precise fit and superior clamping force in assemblies sensitive to vibration. The zinc-plated finish offers a protective layer against corrosion, ensuring longevity in various environments. Packaged in quantities of 500, this nut is supplied for efficient bulk procurement and high-volume usage.
Key Features
Manufactured from Grade 4 carbon steel for high tensile strength and durability Fine thread pitch of 1.5 mm (approximately 16.9 threads per inch) for secure, vibration-resistant connections Low-profile, thin design for use in spaces with limited clearance Zinc plating provides a reliable barrier against rust and corrosion Standard hex design allows for easy installation and removal with common wrenches Bulk packaging of 500 units supports continuous production and project needs
