Question about Jack Posts

Greetings!

Contractors installed a single jack post (Peak Products, Model 2314) in my basement to hold the first floor.

They used only one bolt to fasten the telescopic extension:

However, in the pictures on the manufacturer's website it is fastened with two bolts:

Do you know if this is fine?

I am worried that the whole weight is sitting on just one bolt. Thanks.

Not an expert on this brand, but I've seen lots of basements with a single post using a single bolt.
Generally the load it would be supporting would be the deciding factor.

I'd rather be outdoors camping, kayaking, and mountain biking ...

Where would you put a second bolt?

I've used a brand that only had one provided pin (not bolt).
It appears of similar diameter.
There would be no method to add a second.

That is what I was thinking.
Multiple holes seem to align with the manufacturer's photo, but not the OP's.

The 2 bolt usage from your peak products link is new. For many years it has been one pin.
From your picture you don't have a post with holes punched for multiple bolts/pins usage.
The pic does show a bolt in place of a pin - and that, imo, is not ok.
If it was a high strength bolt I could accept it ... but not with using a std. bolt in today's world, as they can easily be of cheap quality.
I would replace the bolt with a pin to alleviate ANY fears you may have. This Jack Post Cross Pin for example.

It would depend on what this bolt looks like as it may be a custom pin with a hexhead and threaded end to ensure it is secure in place ... similar to what they refer to as a "shoulder bolt".

I would be really surprised to find it to actually be a fully threaded bolt in this application, design wise ... next time I see one I should take a closer look.

Agreed.
It is simply a way to hold it in place.
Something like a hitch pin would work too.
There are many ways to do it.
