What is the standard for threaded rod?
The most common steel threaded rod, classified as ASTM A307, is Grade 2 threaded rod made from low carbon steel. The stronger and more heat resistant Grade 5 threaded rod is made of medium carbon steel quenched and tempered. It is classified as ASTM A449.
What is A36 threaded rod?
A36 is an ASTM specification covering common mild steel round bar which all thread rod is commonly manufactured from. However, it is a steel grade, not a fastener specification. The best option is to find the relevant ASTM standard that covers all thread rod, such as A307 Grade A, A307 Grade B, or F1554 Grade 36.
How are threaded rod sizes measured?
To measure the diameter of screws and bolts, you measure the distance from the outer thread on one side to the outer thread on the other side. This is called the major diameter and will usually be the proper size of the bolt.
What are the sizes of threaded rod?
Threaded Rod Sizes Chart
|Thread Size||Major Diameter||Thread Pitch (mm)|
What are the different grades of threaded rod?
There are three grades: A, B, and C*, which denote tensile strength, configu- ration, and application. Refer to the Mechanical Properties Chart for the subtle strength differences within each grade. Grade A Headed bolts, threaded rods and bent bolts intended for general applications.
What is the shear strength of threaded rod?
The shear strength of 1/4-20 threaded rod is 1,590 pounds.
Is A307 threaded rod weldable?
A307 bolts, rods, and studs are not always weldable. For this grade to be weldable it must meet the supplementary requirement S1 of the ASTM A307 specification. This supplement provides assurances of weldability by additional chemical composition restrictions and by a carbon equivalent formula.
Where is threaded rod used?
Threaded rods are used in a variety of sectors and for several purposes such as construction, plumbing, manufacturing, marine, agricultural, oil extraction and contractor work.
How wide are threads?
The major diameter is the outer diameter at the top of the thread crests. Thread sizes are given in nominal sizes, not in the actual measurement. The exact measurement is slightly below the named or nominal size. For example, a 6mm bolt may measure 5.8mm or 5.9mm, but it is called 6mm bolt.
What size is #10 threaded rod?
|Diameter in inches:||0.190″|
What size is a #8 threaded rod?
32 x 36 in
#8-32 x 36 in.
How do I specify a threaded rod?
When specifying a threaded rod, the length comes after the class of fit. The two are commonly separated by an “x” (read as “by”). Length should be in units of inches for Inch-Standard fasteners and millimeters for Metric fasteners.
How big is an ASTM A307 thread rod?

What kind of fastener do I need for a thread rod?
* ASTM A36 is a steel grade, not a fastener specification. Technically, all thread rod made from A36 steel should be ordered to a fastener specification such as A307 Grade A, A307 Grade B, or F1554 Grade 36. The appropriate fastener specification will depend on the application.
Are there different grades of all thread rods?
There are three common grades (2, 5 and 8) that readily available or can be made as fully threaded rods. 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.
How tall is a Portland bolt thread rod?
Stock grades are indicated by part number below in black text. Red part numbers indicate all thread rod that can be made to order but is not stocked. All grades of stock all thread rod can be shipped in 6’, 10’, or 12’ lengths, or cut to length prior to shipping.
