Grade 8 Threaded Rod Strength

Steelmasters is a manufacturer distributor of threaded rod high tensile 8 8.

Grade 8 threaded rod strength.

The appropriate fastener specification will depend on the application. Zinc yellow chromate plated steel threaded rods resist corrosion in wet environments. Threaded rod high tensile 8 8 steel galvanised din 975 2411392. The second figure signifies that the fastener will begin to yield at 80 of the ultimate tensile strength i e.

As 0 7854 d 0 9743 n squared where d equals nominal diameter in in. M36 x 3 metre long studding threaded rod. 84 3075 nzd each m6 x 1m blk 8 8 ht ftr. Proof loads and tensile strengths are computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread.

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. Black oxide steel threaded rods have a dark surface color and are corrosion resistant in dry environments. M5 x 1m zp 8 8 ht ftr. Grade 8 has 0 28 0 55 carbon 0 030 max phosphorus and 0 050 max sulfur.

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. High tensile grade 8 8 fully threaded galvanised studding. For technical drawings and 3 d models click on a part number. Grade 8 steel threaded rods are about 25 stronger than medium strength steel rods.

It is also quenched and tempered at 800 f leading to its strength. And n equals thread per inch. In the case of a 8 8 grade bolt the first figure signifies that the tensile strength is at least 800mpa. Astm a354 is the classification for grade 8 threaded rod made of high strength steel quenched and tempered.

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.
