End-Viewing Target
The 717 Series paired line target has a pattern which is machine engraved and black-filled on white acetyl plastic. The target is centered within ±0.0005" (0.013 mm) of the centerline of the plug. This target is very useful when sighting an optical instrument directly on the center point of a tooling reference hole.
Standard plug diameter is 0.250" although as with many of our targets, special variations are available on request.
Please refer to the table below for a listing of target pattern spacings (distance between the target lines) and corresponding order number.
