Unified Thread Ring Gage Size from No.0-80UNF to 1/2-13UNC

UNS thread gauge is Unified Special Pitch thread gauge; UNEF thread gauges is Unified National Extra Fine thread gauge; UNF thread gauge is UNIFIED NATIONAL FINE thread gage; UNC thread gage is Unified National Coarse thread gage with 60 degree thread angle; UN thread gauge is Unified Constant Pitch thread gauge.
Application of Unified Thread Working Plug Gauge: Comprehensive inspection of unified internal threads specified in ANSI B1.1-1982 and FED-STD-H28, H28/3 (1978)
ANSI unified thread working plug gauge inspection environment: standard temperature 20°C ± 1°C, standard condition measurement force is zero.
Unified Thread Working Plug Gauge Inspection Method: The length measuring instrument uses the “three-needle method” to detect a single mean diameter. The universal tool microscope can detect pitch, half angle, minor diameter, and clearance groove.
