Questions & Answers


will it rust?

Asked by Mike April 16, 2021

Hello Mike, ATR5/8X36ZP threaded rod has zinc plated finish which doesn't provide adequate corrosion resistance for exterior applications. It should only be used in interior dry conditions. Hope this helps. Regards.

What threads per inch does this have

Asked by Vnick January 28, 2020

The ATR7/8x12ZP has a 7/8-9 thread (9 threads per inch). Thank you!

How many threads per inch and what size bolt will thread on to the rod?

Asked by dynomike12 September 23, 2019

The ATR1x36ZP has a 1-8 thread. Thank you!

Looking to use it as a small axle cart with 2 axle, 4 tires, is it durable enough to hold up to 300 pounds?

Asked by Tom1911 August 19, 2019

The ATR threaded rods are rated for axial tensile load only and the primary loading that this rod would see in the application you are requesting would be a bending and/or torsional action. What we can offer is to let you know that the ultimate tensile strength of these rods is 58,000 psi and the yield strength is 36,000 psi. From a tension standpoint, this particular threaded rod (5/8” diameter) has an allowable tensile capacity of 6,675 lb. The bending and torsion capacity is out of the scope of what we can provide. Thank you!

How many threads per inch. is it 13, is it 18?

What grade of steel is used in these?

Asked by Tom February 25, 2019

We source a few different specifications for the all-thread rod, but all with a minimum tensile (Fu) of 58,000 psi and minimum yield (Fy) of 36,000 psi. Typically it is ASTM F1554 Grade 36. Thank you!

Asked by USMCBULLDOG August 15, 2018

There is not a general rule...the anchor embedment must be specified by the Engineer of Record and there are many factors that come into play (type of adhesive used, concrete strength, how close to the edge/end, spacing, etc.). Thank you!

Asked by Builder November 17, 2017

Torque values for ATSM 1554 are generally not given. The book says that whatever tightening that can be accomplished by an ironworker with a spud wrench is sufficient. If you don’t know what a spud wrench is, think of a crescent wrench with a spike for a handle.

Asked by paul August 25, 2017

Unfortunately I cannot use them. I needed 5/8-18 rods. Although I New the rods were 18 inches long, I assumed the TPI was as well. I could not find any TPI information in the description during the purchase. But the shipping was fast.

Threaded Rod
This was very well packed and very nice but it was too large for my use so I am replacing it with a 1/2 by 36 inch threaded Rod. Overall it was very high quality and would have been useful if I had needed a one inch diameter threaded rod so I am returning it. I will give it a good review as it seems to be very well built and would be useful for someone who needed such a product.
