The standards for astm a36 threaded rod cover multiple parameters such as nominal diameter, lead and length. When designing, it is necessary to select the appropriate specifications according to the specific application requirements and load capacity.
a193 b7 all thread a449 threaded rod nominal diameter:
a449 threaded rod have a wide range of nominal diameters, and common specifications standard threaded rod sizes product are 12, 14, 16, 20, 25, 32, 40, 50, 63, 80, 100, 120, etc. However, it should be noted that most manufacturers mainly have spot stocks of diameters from 16 to 50, and most of the other diameters are futures, that is, they are produced according to orders, and the delivery period is usually between 30 and 60 days, which may be 2 to 2.5 months for Japanese products and 3 to 4 months for European and American products. The nominal diameter is basically proportional to the load capacity, that is, the larger the diameter, the greater the load capacity. When designing, the concepts of dynamic rated load and static rated load should be referred to, where the dynamic rated load refers to the rated axial load in the moving state, and the static rated load refers to the rated axial load in the static state. In actual use, the rated load is not the maximum load. The smaller the ratio of the actual load to the rated load, the longer the theoretical life of the screw.
stainless steel threaded rod astm Lead
also known as pitch, refers to the distance the nut moves linearly for each rotation of the screw. stainless steel threaded rod astm manufacturer Common lead specifications include 1, 2, 4, 6, 8, 10, 16, 20, 25, 32, 40, etc. The spot products of small and medium leads are generally only 5 and 10, while large leads are mostly futures. Lead is related to linear speed. When the input speed is constant, the larger the lead, the faster the speed.
astm f593 threaded rod Length
The length of the astm f593 threaded rod products includes two concepts: the total length and the thread length. When designing and drawing, the total length of the screw can be roughly accumulated according to the following parameters: total length of the screw = effective stroke + nut length + design margin + support length at both ends (bearing width + locking nut width + margin) + power input connection length (if a coupling is used, it is roughly half the length of the coupling + margin). It is particularly important to note that if the length of the screw is very long (greater than 3 meters) or the aspect ratio is very large (greater than 70), its design and application may need special consideration.
