TEXALAN(R) Steel Pin Gage Set Minus Heat Treated with Storage Case M1 190pcs 0.061"-0.250"

Nice box, accurate pins.

i load my own ammunition for a variety of revolvers, each with potentially different chamber mouth diameters, forcing cone diameters and barrel groove diameters. trying to measure the internal diameter of cylindrical holes to the thousandth (0.001) to determine the correct bullet size for a particular revolver is problematic with a 0.001 dial caliper. these minus size pin gauges are perfect for this purpose. they also will easily identify if the chamber mouths are the same diameter as the others in a particular cylinder, and if undersize, what size reamer is necessary. i've already learned more about my firearms. if you reload or do light gunsmithing, you will find these worth the price. randomly measuring five gauges with a micrometer reveals them to conform to the specification of zz minus.

Upon receiving I immediately took a Mitutoyo micrometer to the 0.250", 0.187" and 0.125" pins and all were exactly to size minus 0.00015".Very impressed, great value

gauge pins made nice. only thing im not happy with is the corner radius is big.

Nice range of pins. Seem to be pretty close tolerance wise.

Great

I've been using this brand for years now. I used them in the last machine shop I worked in, I changed jobs and now have to buy my own tools. Knowing how perfect these were I had no worries with making the purchase. I wish they came with the go, no go holder. I purchased that separately for around $15 and it fits in the case.

The set was well packed. Pin accuracy is right on, based on the dozen I spot checked. Some minor variations in chamfering on some of the pin ends (no big deal).

I purchased this pin gage set to learn and explore how to measure known small dimensions with a barrel micrometer. This set, which is reasonably price, ticks those boxes. I also wish to use the set to measure the small passageways found in Solex carburetors.The pins are made of ferrous metal so I must keep them away from humidity or they will rust. If you purchase this kit be very careful opening the box. If you spill the contents you will have a lot of difficulty returning them to their correct spots. I might colour code them just in case I make a mistake and mix them up. I plan to always return one to its spot before removing a second one.
