How do I calculate the length of the bolt that I need?

• For A325 is attached link
• For A307 a good rule is to take your grip length (link to grip length page), add one bar diameter (for nut) add 1/8” for each washer and add ¼” to ½” thread length past nut.

Can I galvanize A193 B7, A325, or Gr5 Bolts or Material?

Yes, material with tensile strength of 130ksi and under should galvanize but we strongly recommend the following:

1. Use a fastener manufacturer or supplier that is familiar with the process involved in doing this.
2. Confirm that the Galvanizer performing this work is aware of how to avoid hydrogen embrittlement, the specification that they are galvanizing to.

What is the difference between A563 DH nut and A563 2H nut?

ASTM A563 Grade DH nuts and ASTM A194 Grade 2H nuts are commonly used with the following ASTM Bolts:
• A307 Grades A and B
• A449 Type 1
• A325 Type 1
• A354 Grades BC and BD
• A490 Type 1
• F1554 Grade 36, 55, and 105
Due to A563-DH’s lack of Availability, A194-2H is commonly substituted when A563-DH is unavailable, but both can be substituted for each other.
There is only one instance where they cannot replace one another and is when using A193-B7 Bolts, you MUST use A194-2H Nuts, A563-DH Nuts cannot be used with A193-B7 Bolts.

What is the difference between Gr5 and A193 B7?

• 5 is primarily used in OEM applications, mainly the automotive industry, A193-B7 is used for many anchor bolting systems as well as Valves and flanges.
• In regards to strength A193-B7 is slight stronger than Gr. 5 as seen below:

How long does it take to make non-stock or custom bolts?

Generally Pacific Bolt tries to manufacture product as fast as possible but a good rule when planning for projects is:
-1 week for bare metal products –
-1 week for heat treat – anything forged that Gr5, A325, A193 B7
-1 week for galvanizing
In emergency cases we have been able to manufacture, heat treat and galvanize product in 2 to 3 days but

What is Hydrogen embrittlement and how does it happen?

Hydrogen embrittlement is the loss or partial loss of ductility in steel due to the possibility of atomic hydrogen being adsorbed by the steel.
Steels susceptibility to hydrogen embrittlement is influenced by many factors: steel grade, heat treating, cold working, size, design, etc. During the acid pickling reaction of the galvanizing process there is the potential to introduce hydrogen atomic which may result in embrittlement happening. Hydrogen Embrittlement generally is only a factor in steel with a 150KSI yield or greater or material that has been severly bent or formed. Pacific Bolt will not galvanize material with tensile greater than 145 KSI Tensile and takes extra steps in preparing steel with 105 KSI or greater Tensile to limit any chance of embrittlement on these items.
Recommend Reading ASTM A 143 – Standard Practice for Safeguarding Against Embrittlement of Hot-Dip Galvanizing.

How to I calculate torque?

What is Charpy Impact Testing? Can you do it?

Charpy or Charpy V-Notch is a standardized test which determines the amount of energy absorbed by a material during fracture. The test is designed to measure a materials’ toughness and temperature-dependent ductile-brittle transition. The Charpy tests report shows the results for the value of Joules at a given temperature. This test is common for bolts or fasteners used in cold temperature applications. Example: 20 joules @ -20 Deg Celsius

Yes, Pacific Bolt does this testing using a third party accredited testing facility. With our years of experience we can generally advise if the bolts being produced will pass or fail a charpy test based on the material and Charpy test requirements provided.

Can Pacific Bolt cut threaded rod to length for me or is it more cost effective to do it myself?

Yes, Pacific Bolt can cut your threaded rod to length and we can save you money doing it because our equipment is built for it. We can cut, chamfer, and stamp (A193 B7) much faster than a person can do it in the field.
You pay for the material you need and not the crops.
All our A193B7 or alloy threaded rod is stamped with a grade marking on the end so you know what it is and avoid the costly mistake of mixing up product or trying to figure out what is what.

Can Pacific Bolt arrange delivery?

Yes, on request we can arrange your delivery! We find that because we ship so many orders daily, most of the freight companies give us great rates. We’ll find the best rate and schedule delivery for when you need it, saving you time and money!
