Why Your Projects Demand Precision: M8 Threaded Rod Technical Superiority

M8 rods (8mm diameter) deliver 1.25mm pitch perfection – the Goldilocks zone between M6’s fragility and M12’s overkill. Our ISO 898-1 certified rods withstand 12,500 N tensile load – 18% stronger than industry averages. Need a nut? The 1/2 threaded rod nut size pairs seamlessly for vibration resistance.

FAQS on m8 threaded rod size

Q: What is the standard size of an M8 threaded rod?

A: An M8 threaded rod has a nominal diameter of 8mm, with a standard thread pitch of 1.25mm or 1.0mm. It is commonly used in light to medium-duty applications.

Q: How do I choose the right size threaded rod for my project?

A: Select a threaded rod size based on load requirements and application. For example, M8 suits lighter loads, while M12 or 1/2-inch rods handle heavier structural needs.

Q: What are the dimensions of an M12 threaded rod?

A: An M12 threaded rod has a 12mm nominal diameter and a typical thread pitch of 1.75mm. It is stronger than M8 and ideal for medium to heavy-duty uses.

Q: What nut size fits a 1/2-inch threaded rod?

A: A 1/2-inch threaded rod requires a 1/2-inch nut, with a thread pitch of 13 threads per inch (UNC) or 20 threads per inch (UNF). Always match the nut to the rod’s threading.

Q: Is an M8 threaded rod compatible with a 1/2-inch nut?

A: No—M8 (metric) and 1/2-inch (imperial) have different diameters and thread pitches. Use metric M8 nuts for M8 rods and imperial nuts for 1/2-inch rods.
