HEMCO Chrome gages provide a substantially longer life than plain steel or other imitation chrome
plated gages – almost 400% longer!

HEMCO gages are supplied with a Certification of Compliance at No Charge.

The Go Ring gage simultaneously checks all the thread elements of form, lead and pitch diameter so that the cumulative effect of errors can be determined. The Not Go Ring gage checks one thread element only-the pitch diameter. The Minor diameter and the Major diameter are cleared beyond those of the Go ring gage. Thus the Go ring gage, in going on the part, insures that the lead and form are correct, and the size is smaller than the maximum permitted pitch diameter of the part. The Not Go gage, in refusing to go on the part, insures that the size is larger than the minimum permitted pitch diameter.
