    I'm not a machinist but I use these for setting up jigs for welding and other things and just spray some anti spatter on them everytime before use. They are cheap enough I don't worry about if they get dinged up or weld spatter on them.Would definitely recommend them won't find them cheaper then this.While I can't confirm if they are accurate to +/- 0.0000001" but they are plenty accurate for my use.

    4.0 out of 5 stars Oily

    A.C. · April 4, 2025

    very oily, needs time to dry out but great once it does. Don’t wash it unless you plan to dry very well, it’ll rust.

    5.0 out of 5 stars Good product, no issues yet!

    The media could not be loaded. Very versatile and easy to use and they look good. I’ve used them as machinist’s jacks, for squaring up stocks, as a vise stop and for other things as well. They were well worth the $ and I plan on getting another pair.

    5.0 out of 5 stars Very accurate

    These are very accurate and there's not a whole lot to say because if you're buying this you know what they are forI personally depend very heavily on reviews that are posted on Bolo, as do many other consumers. I not only read what reviewers say, but look to see what their pictures reveal about a products true quality and description. I aim to not only feature the products I review in many different aspects, analyzing many qualities, I also provide my own opinions on ALL the good AND bad experiences I have with the product I review. I take time to learn and use a product as it was intended before I review it, and I have used this specific product thoroughly.My rating system:5 - Met all my expectations. Was described and pictured perfectly. Exactly what I wanted and needed. Extremely useful product and a great value. Would recommend to family and friends.4 - Very good product. Exactly as described. May have a minor flaw, mentioned in the review, that does not detract from the products perceived value. Would recommend to family and friends.3 - Average product. Not exactly as described, or misleading advertising or product pictures. Possibly substandard build quality, or something else explained in the review. Would mention as an option to family and friends, but not recommend.2 - Wouldn't recommend this product. Poor build quality, not close to being as described. Flimsy and fragile. Difficult to use due to product flaws.1 - Do not purchase whatsoever. Usually only given if product lasts only a few hours/days/etc. I do not leave 1 star reviews without contacting the seller. I will be returning the product.I did NOT receive ANY discount for this product. I simply enjoy reviewing every one of my purchases.

    5.0 out of 5 stars Sturdy, accurate and useful.
