Threaded rods proof load capacities in metric units.
Computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread.
It is also quenched and tempered at 800 f leading to its strength.
Grade 8 steel threaded rods are about 25 stronger than medium strength steel rods.
There are astm specifications that have similar strength properties which may be easier to find in the form of all thread rod than their sae equivalent.
Mass and weight the difference.
Our grade 8 threaded rods vary in length from 10 to 52 depending on the diameter of the rod.
Grade 8 has 0 28 0 55 carbon 0 030 max phosphorus and 0 050 max sulfur.
Sae threaded rods do not require permanent grade markings on the ends of the rods like many astm specifications do.
Where d equals nominal diameter in in.
Astm a354 is the classification for grade 8 threaded rod made of high strength steel quenched and tempered.
1 the maximum loads in the table above are based on allowable tensile stress of 12 kpsi reduced by 25 to 9 kpsi allowable stress.
