Carbon Steel M16×300 Grade 8.8 Galvanized / Black Full Threaded Bar

Precision M16×300 Sizing for Global Compatibility
With exact M16 diameter and 300mm length, this fully threaded bar adheres to strict Metric system tolerances for seamless integration with standard nuts, couplers, and anchor plates. The continuous threading allows flexible positioning and secure fastening at any point along the bar—saving time during assembly and adjustment on-site.

Dual Surface Protection: Galvanized or Black Finish
Choose the coating that matches your environment.
Our hot-dip galvanized (Galv) option provides a thick zinc layer for exceptional rust resistance in outdoor, marine, or high-humidity conditions. Prefer a sleek, cost-effective solution. The black oxide (Black) finish offers basic corrosion protection with reduced glare—ideal for indoor industrial use. 
Both treatments ensure smooth thread engagement and extended service life.

OEM/ODM Customization Supported
Your project, your specifications. We fully support OEM/ODM customization, allowing you to tailor length, thread pitch, coating, packaging, or material grade to match unique engineering requirements. 
From prototype development to large-scale production, our flexible manufacturing ensures you receive exactly what your application demands.

Trusted Across Critical Industries
These M16×300 threaded bars are widely deployed in oil and gas offshore piping systems, where vibration resistance and corrosion protection are non-negotiable. 
They also excel in general industry equipment assembly, structural bracing, and heavy industry applications like mining, power generation, and infrastructure construction. When failure isn't an option, choose a fastener built for the job.
