TEXALAN Class ZZ Steel Pin Gage Set Minus (250PCS (0.251-0.500) M2)

Very useful tool; exactly what I wanted. Appears to be precise, well made and the numbers are easy to read.

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. ive 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.

Only started to use the pin gages to measure diameter of bored holes. Measuring pin gages with a caliper, the gages Ive used appear to be right on in diameter.

You basically get what you pay for. The pins themselves are ok but the beveling on the edges of each pin are not consistent. Some have deeper bevels while others barely have any. Found a couple that had sharp edges. Might be best to spend a little more to have better maid gauge pins.

Love them, Can I buy replacement pins for this?

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.

Great product

Well packaged, easy to access the pins and all the pins I have measured have been spot on size wise. Excellent value.

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).

Solid kit.
