Great for sizing and sorting nuts and bolts

Verified Purchase

All the thread checkers actually worked!!!! This was the forth sizer I bought and the first I didn’t return. The others had one or more checker that would not accept screws or nuts.

The screw sizer on the bottom is not very useful once mounted on the wall.

A Durable Product that is and does what it is billed to do.

Review: The Wall Mounted Thread Checker *****
What can I say? This product does exactly what it was built do to and has stood up the abuse of it. We have had the thread checker now almost six months now. There is nothing less that comes close. We have looked. How did we put it through its paces? Hire two high school students to help clean and organize a small boat building shop that’s been in need of it over twenty years. You know how crusty old guys get about knowing “where everything is in the shop”. Well now that he needs to write notes as reminders all the time, that’s not the case anymore. Enter the “summer interns”.

Not knowing what a fastener even is and that they may threads, we needed this type of product. And a small sheet of plastic with holes wasn’t going to cut it. After going through bins upon bins and thousands of screws, nuts, bolts, etc. they can now tell the difference between #6 and #8 screw or nut. What taught them and expedited the project? The Wall Mounted Thread Checker.

What more can be said? It looks damn good too. Hell it’s a modern art master piece you don’t mind looking at. It looks good mounted on wall.

Review: Ascent Distribution *****
I need to put in a quick statement about Ascent Distribution, Outstanding customer service. The original order was lost by UPS. Ascent couldn’t have been more helpful and making sure we received a new one. They went way beyond what most companies would do to ensure satisfaction, calling after hours and with follow up emails. These people work their butts off even reopening the investigation when UPS closed it down. Thank you Ascent Distribution and specifically John. Consider them for your gauge and die needs.

Review: UPS **
UPS as a company may care as to if your package is delivered, but the Los Angeles distribution center, “don’t like it, call a competitor, ha, ha, ha! … <click>!” There needs to be a serious shake of management there. I would like to give a higher rating but I can't since my packages have to go through the LA center.

After opening an investigation into the lost package, UPS closed it and left it at that. It took both myself and the seller, Ascent Distribution, to put pressure on UPS to reopen it. The follow up consisted of my driver arriving a few days later saying, “I don’t know what happened to your package because I delivered it here and a woman signed for it”. Really no woman was here that day. “Sign this form saying you didn’t receive the package, but if you do then from here on a signature will be required for every package”. Nice blackmail move driver. To make it better, during this exchange, my neighbor comes up to us with a package and hands it to the driver. The UPS driver had just delivered a package next door that belonged to the address down the street. I no longer wondered what had happened to my original package.

I called the only number available for UPS, the national call center. I would have preferred to speak with someone locally because that is where the problem lies. Now the national call center actually cared enough to force a second review and was really upset over that exchange. They apologized profusely for it and promised someone from the LA office would call too. That did happen and within an hour. You saw the end quote above from our two minute conversation, of which I remain calm and composed throughout the call. The drive had made a mistake and was reacting badly to it. However and obviously management’s attitude permeates down to the drivers, “Look the package is being listed as lost, what do you care? It’s up to the driver if he wants to force a signature for all packages. Don’t like it, call a competitor, ha, ha, ha! … <click>!”

I normally don’t write reviews, in the past always took a sample screw or nut with me to hardware store to make sure I got the right one. This is nicer than the one they have. Awesome!

exactly what i needed for all those miscellaneous nuts

Reviewed in the United States on November 1, 2023

exactly what i needed for all those miscellaneous nuts , i have used it countless times already.. I like how narrow and compact it is. It was easy to find a small verticle wall area to hang the thread checker. The unit has a slight bow like other buyers have noted but nothing that affects its use. maybe they could insert a length long steel or aluminum square tube along the center spine to give the plastic body some additional rigidity?

Great tool, not made of wood.

Reviewed in the United States on August 27, 2018

This is a good niche tool. I'm cleaning and organizing my shop, and in the process, I'm trying to recover and sort all the bolts and nuts and screws I've been finding. This is going to be instrumental in helping me sort them quickly.

Some people have been down-rating the thread checker because its warped when it arrives. Honestly, that's some nonsense nitpicking. Yes, it may be warped, but once it's screwed to the wall (mine is going on the support post in my shop), the warping won't matter.

From what I can tell, it's not made of wood. The back plate that the threads are mounted to is 0.46in/11.8mm thick. It appears to be some kind of thermoplastic, maybe HDPE or polystyrene. Using my soldering iron, it gets soft at 350*F, though I couldn't go lower so I couldn't find the exact glass transition point.

It gets pretty melty in the 450*F neighborhood, then will start to yellow and char over 500*F. Cutting off a slice and hitting it with a blow torch (which I did before the soldering iron test) resulted in it just shrinking and burning though, I couldn't get it to maintain its own flame or drip so I thought it was originally a thermoset plastic.

The text on the label appears to be applied to the backside, so the user-facing side protects it. I put a couple drops of B12 Chemtool (primarily acetone with some tolulene and 2-butoxyethanol) and wiped it off after 30 seconds and the plastic label didn't even get gummy and the text was untouched. The label is about 8 mil (0.008in) so it can tolerate some bumps and scrapes, but I don't imagine it'll withstand gouging with tools. So, just don't throw your tools and fasteners at it.

The inserts feel solid. I couldn't find any wiggle in any of them. They are threaded in and they are inserted the full thickness of the back panel (~1/2"). I just got am M5 bolt jammed in one and when I used a screw driver to remove it, the insert threaded out. I grabbed it with a channel lock and removed the bolt, then threaded it back in. It looks like they used a little locktite, but this one didn't have much, so I applied more.

This is a solid tool. In short, this thing should last a long time especially if its mounted up out of the way.

SUPER Handy

Reviewed in the United States on June 26, 2023

We have all seen and used this device in the hardware store.

Now I'm VERY happy I finally purchased this thread checker tool.

Mine is mounted on the door jamb to my workshop storage room using three ¼"x2" hanger bolts, washers and hand tightened nuts permitting easy removal for remote usage.

Others had mentioned curvature of the PVC board. Mine was flat when removed from the box, but had a slight curve prior to being mounted. It was easy to again being flat when tightening the mounting hardware.
