1 2 Threaded Rod Strength

The appropriate fastener specification will depend on the application.

1 2 threaded rod strength.

Black oxide grade b7 steel fully threaded round rod 3 8 16 diameter x 36 00 length 1 pc. However some companies stock all thread rod manufactured from a36 steel and can certify it as such upon. They meet the pressure and temperature requirements of astm a193 and are often used to secure pressure tanks valves and flanges. Threaded rods proof load capacities in metric units.

Din 975 meets german standards for threaded rods. Astm f593 meets standards for stainless steel bolts hex cap screws and studs of diameters 1 4 to 1 1 2. 1 kg 9 81 n. Note that hangers supporting steam water air or gas piping systems should be able to carry the weight of piping insulation valves and other equipment.

Proof loads and tensile strengths are computed by multiplying the proof load stresses and tensile strengths stresses by the stress area of the thread. 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. Grade b16 threaded rods maintain their strength at higher temperatures than grade b7 threaded rods. Made of alloy steel that has been heat treated they are typically used in high pressure applications such as valves and pressure vessels in petroleum and chemical equipment.

Mass and weight the difference. It also covers socket head cap screws 1 1 2 and smaller. And n equals thread per inch. As 0 7854 d 0 9743 n squared where d equals nominal diameter in in.

The rod features an electro galvanized finish and has a 3 500 lb. Each piece is 10 ft. Threaded rod is classified by the american society for testing and materials international by grade material and strength. Black oxide grade b7 steel fully threaded round rod 1 2 20 diameter x 12 00 length 2 pcs.

Black oxide grade b7 steel fully threaded round rod 3 8 16 diameter x 72 00 length 1 pc. 1 the maximum loads in the table above are based on allowable tensile stress of 12 kpsi reduced by 25 to 9 kpsi allowable stress. Astm a193 grade b7 fully threaded rods and studs provide high wear resistance high temperature resistance and high strength. Long with a 1 2 in.
