Grade 5 Threaded Rod Equivalent
Same as grade 5.
Grade 5 threaded rod equivalent. Common finishes include plain black zinc plated and hot dip galvanized for. Strength is similar to grade 5. Bolts meet astm a325 type 1 standards for structural steel joints. Grade b7 threaded stud rod.
Grade 8 has 0 28 0 55 carbon 0 030 max phosphorus and 0 050 max sulfur. It is classified as astm a449. Strength exceeds grade 5. Grade grade 5 astm a193 b7 chromium molybdenum grade 8 heat treated after threading tensile strength 120 000 psi minimum 125 000 psi minimum 1 100 f tempering temp 150 000 psi minimum yield strength 92 000 psi minimum 105 000 psi minimum minimum 130 000 psi minimum rockwell hardness c25 c34read more.
Use with grade 2h and grade c nuts. 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. 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.
The threads per inch tpi also varies on the diameter of the rod as follows. Steel threaded rod grades and specifications the most common steel threaded rod classified as astm a307 is grade 2 threaded rod made from low carbon steel. Grade a 396 18 8 102 304 1 316 59 651 2 6061 10. Our grade 5 threaded rods vary in length from 6 to 36 depending on the diameter of the rod.
Grade c nonheaded anchor bolts either bent or straight intended for structural anchorage purposes. 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. Zinc yellow chromate plated steel threaded rods resist corrosion in wet environments.
1 1 2 6 5 12 11630 10370 performance data grade a headed bolts threaded rods and bent bolts intended for general applications. This grade is for fittings flanges valves and pressure vessels. It is also quenched and tempered at 800 f leading to its strength. For technical drawings and 3 d models click on a part number.
This chromium molybdenum steel has similar strength to sae grade 5 fasteners however it is specifically used in high temperature and pressure applications. Grade 8 steel threaded rods are about 25 stronger than medium strength steel rods. Strength exceeds grade 2. Sae threaded rods do not require permanent grade markings on the ends of the rods like many astm specifications do.
This table shows the mechanical properties of b7 grade 5 and grade 8.
