Grade 5 threaded rod yield strength.
Astm a354 is the classification for grade 8 threaded rod made of high strength steel quenched and tempered.
The stronger and more heat resistant grade 5 threaded rod is made of medium carbon steel quenched and tempered.
Grade b heavy hex bolts and studs intended for flanged joints in piping systems with cast iron flanges.
6al 4v grade 5 titanium is much stronger than commercially pure titanium but still has the same stiffness and most of the same thermal properties it is much lower in 6al 4v grade 5 than other alloys.

This table shows the mechanical properties of b7 grade 5 and grade 8.
5 tpi threaded rods.
Grade a headed bolts threaded rods and bent bolts intended for general applications.
Sae threaded rods do not require permanent grade markings on the ends of the rods like many astm specifications do.
Common finishes include plain black zinc plated and hot dip galvanized for grades 2 and 5.
Grade 2 requirements for diameters ranging from 1 4 through 3 4 only apply to headed fasteners up to and including 6 in length and to studs of all lengths.
Proof loads and tensile strengths are computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread.

Zinc yellow chromate plated steel threaded rods resist corrosion in wet environments.
And n equals thread per inch.
Grade 8 is typically provided plain finish only due to the potential risk of hydrogen embrittlement when plated or galvanized.
It is classified as astm a449.
