What is all thread and some common questions about threaded rods

July 12, 2024

Allthread is also commonly known as threaded rod or threaded studs. It is typically used within building, maintenance and plumbing applications to stabilise objects that are made from wood, metal or other materials.

Thread rod. Do fasteners deal with every day, but many people will always ask why the same thread rod size price is not the same, what is the difference between them, why this will be more expensive than that, often said that the thread angle of what it means and so on a series of questions, so now I will be on the weight of the relationship between the weight of the thread rod, the relationship between the thread rod angle and the single weight of the thread rod of the several common problems to answer your questions.

  First of all, the thread has a large diameter (d), small diameter (d1), small diameter (d1) is a size of our screw under the thread rolling before, and large diameter (d) is a size of the screw rolling after a size of the nominal diameter is on behalf of the diameter of the thread size. For example, we often say 3/8 thread rod, din 975, M12 these are large diameter (d).

Why two thread rods of the same size will have different weights and different prices?

Thread rod with the same diameter of the same small diameter is different, the depth of its thread is also different, the thicker the diameter, the shallower the thread, its weight will become larger, the use of raw materials will become more products, so in the same size, the thicker the diameter of the price and the weight will become higher. (The following picture has a real shot display, you can more intuitively see the difference between large diameter and small diameter)

So this is why two thread rods of the same size but the price and weight are different reasons.

Relationship between thread rod angle and thread rod weight

The above mentioned small diameter of the thread rod and thread depth and weight of the relationship, while the thickness of the small diameter is to determine the angle of the thread rod teeth, the small diameter of the thread rod is thick, the angle of the teeth will become larger, the relative threads will become shallower, then the unit weight will become higher.

For example, a one-meter-long 3/8 thread rod with a 60° 3/8 thread rod angle will have a higher unit weight than a one-meter-long 3/8 thread rod with a 30° angle, because the small diameter of a 60° angle 3/8 thread rod is thicker than the small diameter of a 30° angle 3/8 thread rod.

Said so much so how do we go to choose the right thread rod?

Hebei Yunteng has a variety of angles of various sizes of thread rod, such as: 3/8 thread rod, din975, etc., the above description of some of the common problems of the thread rod. Yunteng suggests in the choice of thread rod in the budget as far as possible to choose a single weight high thread rod as our first choice, the same size in the single weight of the low thread rod will be more than a single weight high thread rod for some fastening operations easier to loosen, the occurrence of hazards, such as: the collapse of the house, machinery and equipment, damage to the bridge collapse, and so on.

If you are not sure what kind of thread rod you need, you can consult Hebei Yunteng, who has been in the fastener industry for more than 30 years, and has excellent professional technology, many production lines and enough stock.
