WEN 10481 81-Piece Steel Gauge Block Set with Case

I've bin a machinest.For 3 decades.I always use Jo blocks ,to. Compare, set tools,calibrate.I bought this set.Just for my box.I can say good Quality,the blocks were individually wrapped with rust prevention. Nice case.Great stuff.

These are cheap shop grade gage blocks, but they all appear to be well within 0.00005". I was genuinely curious how close these sets are, and compared them carefully to a set of AS-2 grade blocks with a 0.00002" dial comparitor installed in an ancient bench micrometer, in a temperature controlled environment. I definitely trust these for comparitive measurement to +/- 0.0001" in small stacks. For basically any home shop use they are going to be accurate enough to serve as a shop standard. They wring together decently well, the plastic case they come in is well made enough to use permanently to hold them. The serial numbers and sizes are clearly marked. All the blocks were rust free. The inspection cert these come with is clearly bogus -- you can stack up the outliers and compare with an equivalent stack to see for yourself, you just need a tenths DTI to do it. No surprise there though, since you can't get a single block certified for what this whole set cost. I think everyone understands that with these import sets.

I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now. DR

This is an incredible deal. I'm a woodworker, so my tolerances aren't as tight as a machinist. These work perfect for my needs. I love the case, also. The only thing that kept me from giving 5-star: I wish the face that is marked was more consistent to indicate which is the measuring face. The gages are individually laser-etched w/ their size marking. But the face that is labeled is sometimes the gage face, sometimes it's the non-gage face. This is confusing since the gage face changes after 0.25"

Love this set, precise and work as they are supposed to . Yes, they can be wrung together. Proud to own them. Just take your time cleaning the blocks and apply light oil for storage.

This is not the most precise set you might possibly purchase. Some of the ones that arrived were off by a significant margin. That said, however, it does come with a handy sheet giving the precise measurements of each block to four decimals. So with that to calculate correction factors it's a perfectly good set for the hobbyist or small shop and the small amount of additional effort to use them is more than offset by the price.

Tested these against the metrology tools at work. Very accurate for the price.

Measured every single block with a .00005" mic. About 90% were within .00005", 10% within a .0001". Plenty accurate for my needs. Case is pretty nice. Pretty hard to beat the value of this set relative to cost.

Uso este juego de bloques patron en piso, principalmente para posicionar piezas y usar la mesa de senos, y la verdad me ha funcionado muy bien. Otras opciones estaban en 20 mil las economicas, y este la verdad cumple la funcion.

I am a hobby machinist and this was affordable and seems like a quality set of gauge blocks. I am happy with the purchase and would buy again. There was no corrosion and they ring nicely.

Parami están bastante bien buena calidad aunque sean económicos

Given the low price of these gauge blocks, I was hesitant to buy them; but they happened to be on sale and so I decided to try them. After all, Amazon has a good return policy on Prime items. I have a (out of control) hobby machine shop. I had seen a "similar" Mitutoyo set at a commercial machine shop before, and those had cost them $4800. I got the Wen set within a couple days, and I left it overnight to acclimatize. The next day I randomly picked 10 of the blocks, cleaned them, and checked them using a digital micrometer and a vernier micrometer. (It was a good excuse to compare the readings on my digital mic to the old-school type.) Of the 10 I tested, 7 measured spot-on, and 3 measured less than a 1/2 tenth (0.00005) out. It's also worth mentioning that the ones measuring oversize were also showing oversize on the inspection sheet that came with the set. The finish on the blocks is excellent and they easily wring together to make a stack. For my purposes, these blocks are definitely more accurate than what I need, given the measuring tools I have. Both of my micrometers can only measure to within 1/2 tenth, and beyond that it's pretty subjective. I'm super happy with my purchase.
