Williams 150 ksi All Thread Bar

Williams all thread bar of 150 ksi has been widely used in many industrial applications which requires high tensile and yield strength. With the right material, heat treatment would make the steel rod exceed post tensioning bar and rock anchoring conditions, and after it passed 500,000 times of loading, it makes a very suitable fastener to help create large bond strength to grout or concrete.

• AASHTO M275
  This specification covers Type I and Type II high-strength steel bars intended for use in prestressed concrete construction or in prestressed ground anchors. Bars are of a minimum ultimate tensile strength level of 1035 MPa [150,000 psi].
• ASTM A722
   This specification covers Type I and Type II high-strength steel bars intended for use in prestressed concrete construction or in prestressed ground anchors. Type I bars have a plain surface. Type II bars have surface deformations. Bars are of a minimum tensile strength level of 150 000 psi [1035 MPa].

Longteng 150 Ksi All Thread Rod

AGICO is a high strength steel product supplier in China, we mainly supplies high tensile strength steel rod and bar products such as anchor rod, stud bolt, hexagonal bolt etc. AGICO has developed equivalent fully threaded bar according to the famous William 150 ksi bar, usually our 150 ksi all thread rod tensile strength exceed the standard value of 1026 Mpa. Our all thread bar and bolt products have super high yield strength(up to 1100 MPa) and tensile strength(up tp 1220 MPa). Regarding impact energy, our grade 8.8 anchor bolt everages 60J , grade 10.9 everages 35J which means our products performance much higher than standard requirements.

Q: I’m designing a process that must be able to handle a high load at about 1000F. I’m planning to use A286, but I now need to know what bolt length 

size

to use to make this machinery stable. I’d like to use as short 

small

of a bolt as possible so how many threads do I need to make a strong connection? And should I use fine or coarse threads?See also:

What strength are thread bars?

A: This is two separate questions. First let’s look at fine compared to coarse thread. Fine threads have more threads per inch so this will give you more gripping area in a smaller length. For example a 1/4″ bolt comes in 1/4″-20 which is coarse thread – and has 20 threads per inch. Whereas a 1/4″-28 finely threaded bolt has 28 threads per inch. A finely threaded bolt will allow you more threads on a shorter bolt.  The other major advantage of a fine thread bolt is that it has a larger minor diameter.  This will give the bolt a larger cross-sectional area and allow the bolt to take a larger load (both tensile and shear).  Because of this – fine thread screws are always stronger compared to the coarse thread option of the same diameter.

Now since you want to use as short 

small

of a bolt as possible it’s important that you have the necessary amount of threads in order to handle your load. The answer here can vary but typically we recommend about 6 threads to provide a secure connection. When you apply load to a bolt, it actually will stretch minutely, which causes the first thread to bear 

bare

the most load, then it decreases from there.  After about 6 threads (give or take), it will not improve the bolt’s load capacity
