M12 1.75 60mm Flanged Hex Bolt AOESIN 10point9 Steel, 4pcs

Description

Product Overview

The M12 1.75 mm pitch flanged hex bolt from AOESIN is engineered for demanding industrial applications where strength, durability, and precision are paramount. Constructed from high‑grade 10.9 alloy steel, each bolt undergoes a rigorous heat‑treatment process to achieve optimal tensile strength and hardness. A black oxide coating further enhances corrosion resistance, extending service life even in humid or chemically active environments. The bolt features a partial coarse thread that balances ease of installation with secure load‑bearing capacity. Its large flange washer head, measuring up to 26.6 mm in diameter, distributes stress evenly across the fastening surface, reducing the risk of material deformation or failure. Packaged in convenient sets of four, these bolts are ready for immediate use in a variety of projects.

Usage

Designed for versatility, the M12 flanged hex bolt excels in indoor mechanical assemblies, machinery maintenance, and structural connections. Whether you are securing metal frames, mounting equipment, or reinforcing joints in a fabrication workshop, the bolt’s robust construction ensures reliable performance. Its partial thread length provides a strong grip while allowing for quick installation with standard hex wrenches (18 mm drive). The black oxide finish makes it suitable for environments where exposure to moisture or light chemicals is expected, such as automotive workshops, HVAC installations, and general manufacturing settings. The 4‑piece packaging offers flexibility for batch projects or spare inventory, ensuring you have the right fastener on hand when needed.
