Our HDG Threaded Rod come in different specs and strength grades—they work for all kinds of uses, like industrial jobs, construction, or everyday repairs. Thread sizes cover common standards: metric goes from M3 to M48, and imperial from 1/4 inch to 2 inches. Lengths are usually 100 millimeters to 6 meters, but we can cut them to your needs too. Key parameters are pitch (coarse or fine) and rod diameter, so they fit standard nuts and washers easily.
Strength grades follow industrial standards. The regular commercial grade (like DIN 975) is for general use—plenty strong enough for daily tasks. High-strength grades (8.8, 10.9, etc.) are made of alloy steel, good for structural supports, heavy machinery, or load-bearing jobs. We also offer more precise products, which are suitable for precision equipment with strict requirements for assembly accuracy.
All specs meet standards like ISO 4017 and ASTM, so batch quality stays consistent.With these various specifications and grades, these products are suitable for installation, suspension, support or connection - whether for home repairs or large industrial projects.
Product quality control
We have a step-by-step quality check process for making our HDG Threaded Rod. First off, we test the raw materials—things like component analysis and mechanical performance checks—to make sure stuff like tensile strength and hardness hits the standard requirements.
Next, we do a size inspection. We use special tools to measure thread size, pitch, diameter, and length, so they line up with standards like ISO 4017 and ASTM.
We also check the thread quality carefully. We need the threads to be smooth and the dimensions right, so there’s no trouble during installation. At the same time, we inspect the surface—looking for scratches, burrs, or any other flaws that might mess with how they work.
Every batch gets a random sampling test, and we keep full inspection records so we can trace things if needed. Through these steps, we strictly control the quality of HDG Threaded Rod, ensuring their stability and reliability, whether you are using them for everyday tasks or industrial purposes.
Order of Q&A
Q: What strength grades are available for your HDG Threaded Rod?
A:For the threaded rods sold by the steel factory, the standard performance grades are 4.8, 8.8 and A2-70 (suitable for stainless steel). Grade 8.8 is a common choice for high strength. The appropriate grade selected for the products you purchase can ensure that they can withstand the expected tensile and shear loads.
