Grade 5 Threaded Rod Tensile Strength
Grade a 396 18 8 102.
Grade 5 threaded rod tensile strength. As 0 7854 d 0 9743 n squared. Grade 8 steel threaded rods are about 25 stronger than medium strength steel rods. And n equals thread per inch. Threaded rod tds version date.
5 tpi threaded rods. For technical drawings and 3 d models click on a part number. This table shows the mechanical properties of b7 grade 5 and grade 8. Note that hangers supporting steam water air or gas piping systems should be able to carry the weight of piping insulation valves and other equipment.
Computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread. 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. 1 kg 9 81 n. It is classified as astm a449.

Zinc yellow chromate plated steel threaded rods resist corrosion in wet environments.
Common finishes include plain black zinc plated and hot dip galvanized for grades 2 and 5. Mass and weight the difference. Threaded rods proof load capacities in metric units. Black oxide steel threaded rods have a dark surface color and are corrosion resistant in dry environments.
Sae threaded rods do not require permanent grade markings on the ends of the rods like many astm specifications do. Astm a354 is the classification for grade 8 threaded rod made of high strength steel quenched and tempered. Grade 8 is typically provided plain finish only due to the potential risk of hydrogen embrittlement when plated or galvanized. The stronger and more heat resistant grade 5 threaded rod is made of medium carbon steel quenched and tempered.
For proof load yield and tensile strength values for threaded rod refer online to the astm.
