Grade 8 Threaded Rod Strength

The threads per inch tpi also varies on the diameter of the rod as follows.

Grade 8 threaded rod strength.

Black oxide steel threaded rods have a dark surface color and are corrosion resistant in dry environments. 1 kg 9 81 n. For proof load yield and tensile strength values for threaded rod refer online to the astm sae and iso mechanical requirements for steel fasteners chart or the industrial fastener institute website and handbook which can be found in resources. 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.

Our grade 8 threaded rods vary in length from 10 to 52 depending on the diameter of the rod. Mass and weight the difference. Zinc yellow chromate plated steel threaded rods resist corrosion in wet environments. And n equals thread per inch.

Proof load tensile strength for grade 2 5 8. Lug all permatex cabinets scoop drawers polyboxes. All america threaded products will dual certify to astm a354 bd and sae j429 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.

Threaded rods proof load capacities in metric units. Grade 8 steel threaded rods are about 25 stronger than medium strength steel rods. Rod diameter threads per inch. High strength steel threaded rods.

Astm a354 bd is used for structural bolts while sae j429 grade 8 is an automotive specification. Sae threaded rods do not require permanent grade markings on the ends of the rods like many astm specifications do. Grade 8 has 0 28 0 55 carbon 0 030 max phosphorus and 0 050 max sulfur. Common finishes include plain black zinc plated and hot dip galvanized for.

Threaded rod tds version date. Astm a354 is the classification for grade 8 threaded rod made of high strength steel quenched and tempered. With a minimum tensile strength of 150 ksi and minimum yield of 130 ksi grade 8 has a greater tensile and yield strength compared to other steel grades such as grade 2 grade 5 and b7. Computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread.
