M5 x 1m zp 8 8 ht ftr. It is also quenched and tempered at 800 f leading to its strength. M36 x 3 metre long studding threaded rod. Technically all thread rod made from a36 steel should be ordered to a fastener specification such as a307 grade a a307 grade b f1554 grade 36 or sae j429 grade 2.

Astm a354 is the classification for grade 8 threaded rod made of high strength steel quenched and tempered. Threaded rod high tensile 8 8 steel galvanised din 975 2411392. 3m rite lok lockfast high strength ind. 84 3075 nzd each m6 x 1m blk 8 8 ht ftr.

With a minimum tensile strength of 150 ksi and a minimum yield of 130 ksi grade 8 has a higher tensile and yield strength than other steel grades such as grade 5 and b7. High tensile grade 8 8 fully threaded galvanised studding. And n equals thread per inch. Steelmasters is a manufacturer distributor of threaded rod high tensile 8 8.

Grade 8 steel threaded rods are about 25 stronger than medium strength steel rods. However some companies stock all thread rod manufactured from a36 steel and can certify it as such upon. For technical drawings and 3 d models click on a part number. 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.

The appropriate fastener specification will depend on the application. Grade 8 has 0 28 0 55 carbon 0 030 max phosphorus and 0 050 max sulfur. Proof loads and tensile strengths are computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread. Black oxide steel threaded rods have a dark surface color and are corrosion resistant in dry environments.
