NPG SCREW POSITION GAUGE
Quick and easy position measuring of screw holes.

The accuracy of measuring is 土3um.
High-precision screw position measuring to proceed higher quality production and processing.
 
l  Effective on cost and time reduction.
l  "Knurled handle" will not require any tool for detaching.
l  Point of origin can set by using screw holes.
l  Accurate measurement in fast and cost-cutting method.
 
FEATUERS
l  The position and pitch of screw holes can be measured with high accuracy
l  Fixed with “Knurled handle” to avoid touching the gauge with bare hands
l  The bottom of the measured amount of the screw position gauge has an R surface shape, and the screw position gauge is carried to the center of the screw hole
*In order to measure with high accuracy with a screw position gauge, chamfering that is processed at the same time as the screw part is required.
 
ACCURACY
l  The measuring part (pin gauge) is within土0.003 mm with respect to the outer diameter, and the coaxiality (runout accuracy) between the threaded part and the measuring part is within 0.01 mm
l  The screw grade is equivalent to JIS2 grade (JIS B 0205)
 
METERIAL
l  Gauge steel SKS. The threaded part is machined (non-heat treated).
