## Description

The Metric 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 & 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 counter parts, 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: Great tool for identifying those small metric screws - This is great for all of my hobby work - I should have added this to my toolbox years ago! When you are trying to tell if a screw is a M2 or an M2.5 or an M3 this is indispensable. Small metric screws are more difficult for me to distinguish than the imperial ones I deal with. This tool takes out the guesswork, which is especially important if you need to order some screws to match what's on a part you are working with. This is well made. It is heavy gauge steel with a nice finish and markings. Someone commented that the 'case' is a ziplock bag - well it is, but it's a heavy/thick one that is the exact size of the tool. I think it is appropriate for the purpose. It protects the tool's finish, but doesn't take up a lot of extra room in the toolbox. It also allows you to keep the reference card together with the tool so it handy and keeps it from getting lost (it's not the end of the world if you lose it, but it does have some handy information).
Review: Wonderful but the texture makes me go (shudder) - Fabulous little screw sizing guide and thread tester. Very well thought out and designed, good information. Looks to be sturdy and should hold up (threads shouldn't gall out) for quite some time. Excellent little asset to have around a shop. My one complaint is the texture of the (sintered? Cast?) aluminum it's made out of gives me the heebie jeebies...like fingernails on a blackboard sort of sensation. On the plus side, since my wife hates that feeling even more than I do (can't even stand to touch sandpaper) I can chase her around the garage with it for a laugh.

## Questions & Answers

**Q: Are the hole actualy threaded?**
A: The holes on the left side are the drill sizes needed to make a 'thru hole', and the holes on the right are actually threaded holes, which can be used to check an unknown screw for thread size.

**Q: Do you like these better than the plastic type?**
A: Don't waste your money on plastic. Another advantage, besides durability, is with fine thread you can easily damage plastic by cross threading or inserting the wrong size pitch in the checker. You would have to force the screw in harder for the steal unit before damaging it.

**Q: are the numbers engraved or printed? the reviews say both.**
A: The numbers on my checker are printed. On the standard screw checker are printed also. I bought it 12 years ago, alot of use and abuse and it still looks good. Thanks for reminding me that I could take care of it alittle better.

### ⭐⭐⭐⭐⭐ Screw that
*by C***T on December 17, 2012*

Like many DYI or tinkerers, I have a ton of screws and bolts laying around, usually in cans, jars, or something other unsorted pile. This screw checker helps me sort them all out, so I can organize them into correct sizes, and know if I need to make trip to the hardware store or not. It's also very helpful if a screw gets lost and I don't know what the size was but have one of the same type. Being made of metal, it holds up really well, can be stuck to my toolbox with a magnet, and cleans the threads on the old crusty screws in a decent enough manner. The small size and hard material let it sit in travel toolbox easily without worry of it getting damaged. Overall, very quality item.
