Grade 5 threaded rod equivalent.

Our grade 5 threaded rods vary in length from 6 to 36 depending on the diameter of the rod. The threads per inch tpi also varies on the diameter of the rod as follows. Common finishes include plain black zinc plated and hot dip galvanized for. This table shows the mechanical properties of b7 grade 5 and grade 8.

1 1 2 6 5 12 11630 10370 performance data grade a headed bolts threaded rods and bent bolts intended for general applications. Rod diameter threads per inch 3 8 24. Sae threaded rods do not require permanent grade markings on the ends of the rods like many astm specifications do. Grade b heavy hex bolts and studs intended for flanged joints in piping systems with cast iron flanges.

The stronger and more heat resistant grade 5 threaded rod is made of medium carbon steel quenched and tempered. For technical drawings and 3 d models click on a part number. It is also quenched and tempered at 800 f leading to its strength. This chromium molybdenum steel has similar strength to sae grade 5 fasteners however it is specifically used in high temperature and pressure applications.

Grade a 396 18 8 102 304 1 316 59 651 2 6061 10. Black oxide steel threaded rods have a dark surface color and are corrosion resistant in dry environments. 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. Same as grade 5.

Zinc yellow chromate plated steel threaded rods resist corrosion in wet environments. This grade is for fittings flanges valves and pressure vessels. Strength exceeds grade 5. Strength exceeds grade 2.

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. Strength is similar to grade 5. Grade b7 threaded stud rod. Grade 8 steel threaded rods are about 25 stronger than medium strength steel rods.

Bolts meet astm a325 type 1 standards for structural steel joints. Grade c nonheaded anchor bolts either bent or straight intended for structural anchorage purposes. 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. Use with grade 2h and grade c nuts.

Grade 8 has 0 28 0 55 carbon 0 030 max phosphorus and 0 050 max sulfur.
