1/4-20 UN(J)C 3B THREAD LIMIT GAGE TIN
Go/NoGo w Handle, Class X ANSI B1.2
Description
Inch plug thread gages are used to inspect pitch diameter and pitch accuracy of internal threads. OSG inch plug gages are manufactured to Class X tolerances per ANSI B1.2. Go and No-Go gages from OSG are ground from premium HSS and hardened to 64Rc to ensure superior wear resistance. Gages are available with short form certifications. To order gages with a short form certificate, use the standard EDP number.
