## Overview

The Ruelle Screw Chek'r SAE/Inch Size Gauge is a compact, heavy gauge steel tool designed for fast, accurate identification of screw sizes from No. 1 to 5/16 inch. Featuring satin chrome plating and a protective case, it measures diameter, pitch, and length for various screw types including machine, wood, and sheet metal screws.

## Description

The SAE/ Inch Screw Checker is a precision threaded tool for complete instant identification of both coarse and fine thread metric screws. This quality tool made of heavy gauge steel is satin chrome plated, expertly machined and American made. All do it yourselfers, handymen, mechanics and maintenance people have too often experienced the frustration and loss of valuable time and money by mistakenly identifying a screw. With this easy to use, pocket sized tool you can kiss those problems goodbye. No more headaches, cursing, and multiple trips to the hardware store. Unlike their plastic counterparts, these screw checkers, made of heavy gauge steel, will last for a very long time without the worry of wearing out the threads after a few uses.

Review: Fast, Simple, Reliable, Reasonable Price, Well Made - I own multiple screw sizing tools of various types. Each has its strong and weak points. I found myself reorganizing my bolts and screws, exchanging the plethora of bins, drawers, and boxes for a simpler system. I thought this would be easy until I realized what a mess the contents of all those bins and drawers were. Also, when I started adding a number of Metric screws my ability to immediately know which was what went bye-bye. My new plan was to use 3x6 inch very tough, clear zip-closing plastic bags. I purchased 1000 of from desertcart. Each identical item would go into a single labeled bag. These bags would be collected by size and type into larger labeled bags and then into clear plastic boxes. I would never again spend hours looking through 40 thousand bins looking for what I want. The entire collection of all fasteners of every type fits into 6 boxes in 25% of the spaces. Boy was I surprised. The problem was really how long it was taking me to sort using my existing sizing tools: thread gauges, diameter gauges, length gauges, micrometer, and taps and dies when I was really confused. So I purchased a full set of the three gauges Screw Check'r makes, one SAE and two Metric. This really sped the process up. And it also made some sense out of the nonsense of Metric Screwdome. SAE screws are a very orderly system. Metric is bizarre, especially the odd sizes that are supposed to come close to duplicating popular SAE sizes. 1/4-inch by 20 threads per inch is one of these SAE sizes that are poorly mimicked in metric. Another area that confuses folks is the SAE #12-24, #12-28 and the 1/4"-28 size. It is hard to find the #12 sizes in home centers and hardware stores, but they have been very common in electronic equipment racks. Of course so are metric 6 mm by 1 mm pitch screws and cage nuts. They look similar, but never the twain shall meet. The good news is that what looked like a project that was going to take several weeks of spare time was reduced to two days of spare time. I could not be happier with these Screw Check'r sizing tools. The new organization system has all sorts of surprising benefits. I find the exact screw in seconds. I usually use a number of similar screws in one project and they all usually come from one box--not multiple bins. The screws, nuts, washers, wood screws, sheet metal screws stay clean and orderly. They don't walk between bins. When I use a bag of screws up, it goes into my pocket for ordering replacements. Are Screw Check'r perfect? Nope. They could be better. They could also cost a lot more. As with most quality tools, however, these should last my life time if I take care of them. Positives: Clearly marked, the holes are organized. Study them for a minute before freaking out. Metric is screwy. Get over it. The machining is good. The plates are a heavy, which I like. Sizing a screw is fast. Stores easily in a plastic bag. Negatives: The markings are silk-screened on, not laser etched. However they are coated with a very tough clear finish that seems to be hardened with a silica additive. The use I put them through did not impact the finish at all. It still looks new. A tiny bit of thread on a few of the holes split off, making slight burrs that I cleaned up with a needle file. The thickness of the plate does not provide many threads on some sizes, but there seems to be enough. I would not use one of these plates to clean damaged threads. Nor would I force a screw just because I was certain it had to be a specific size. I would rather throw a recalcitrant screw away, clean it with a file, or rethread it with a die. Probably the biggest shortcoming of these is that they only work on screws, not nuts--and I would never try to size a tap with it. The best part is that it is very fast and certain if you have both an SAE and Metric plate. And I love that.
Review: A huge help in sorting - Maybe with enough practice, you all can sort bolts. Maybe I can too. But it's hard for me to just eyeball the difference between 8-32 and 10-32. And hard, unless side-by-side, for me to see the difference between 4-40 and 5-44. So this has been really useful. I'm sorting my dad's fasteners, to make it easier for me to find things and this plate has been great. Seems sturdy and even helps chase threads for things that are slightly messed up (they don't advertise this, I wouldn't make a habit of it). Note that there's nothing metric on here so if you want that you'll need another plate...

## Questions & Answers

**Q: Lots of bad reviews. Are the latest ones actually 1/8" thick and good quality?**
A: This screw checker is actually 0.080" thick, which is considerably smaller than 1/8" (0.125"). It is made of steel. It works fine for its intended purpose. They need to change the specs to match the actual product though.

**Q: Is this tool for machine type bolts and screws, or can it also be used for wood and sheet metal screws as well?  I saw one review saying so.**
A: The numbered, unthreaded holes down the left side are used to size machine screws or wood screws.

**Q: is their a chart to measur pop rivits to bolt size**
A: Are you asking what size Pop Rivet to use to replace a bolt or screw? Pop Rivets are usually specified two ways. The first is the "diameter" of the hole that is drilled in the two (or perhaps more)for them to fit in. The other is the "grip range" of the thickness of the two pieces being joined. So if you want a Pop Rivet to replace bolt/screw, first measure the diameter of the hole(may use a dill bit for this if you lack other tools) and then the thickness parts you are joining. Good Luck and remember once you Pop Rivet something the only way to take it apart is to drill the Rivet out.

**Q: Are the numbers printed on the surface or embossed into the metal?**
A: It looks very much like they are printed on the surface, maybe with epoxy ink, maybe not, but the thing comes in a nice clear plastic envelope, and I
keep mine in that envelope. I don't use it all that frequently anyway--most screws I recognize, but if I don't, this is a real handy gadget. If you're 
seriously worried about losing the printing, you could Xerox or scan the thing when you first get it, and keep a copy in some safe place.
