SMALL DIAMETER INTERNAL FUNCTIONAL SIZE/PITCH DIAMETER GAGES The SPG-6000 line of thread inspection gages measures internal and external functional size and pitch diameter of thread diameters between .625″ and 1.500″. Mainly, these gages are used on ANSI and ISO standard straight thread forms. Primarily among these groups, the gages are used on the ACME, Stub Acme, Stub ACME Modified-1 & -2, Metric & MJ, and UN, UNJ, & UNR Series of threads. However, these gages are versatile in that they can be modified to inspect nearly any type of thread in our .625″ to 1.500″ size range. The SPG-6000 can be equipped with either thread rolls or contact points. Contact points are applied for pitch diameter measurement, while thread rolls inspect functional size. Pitch diameter inspection requires the addition of contact point arms to hold the contact points. Contact point arms are sold in sets of two. Our standard contact point arms require straight shank contact points. Contact point arms designed for threaded shank contact points are available at additional cost. For functional size inspection, thread rolls attach directly to the gage. Thread rolls for certain thread types may have a designated set for internal threads or external threads, while other thread types have one set of rolls for both internal and external. The SPG-6000 can be set using our MIC TRAC™ gage setting systems, rod standards, calipers, gauge blocks, or micrometers. For best results, Gagemaker recommends our MIC TRAC™ gage setting systems or rod standards. For gage setting dimensions regardless of setting method or selecting additional contact points, our helpful, easy-to-use TDWIN™ thread engineering software program may be required. Contact points, contact point arm sets, thread roll sets, gage setting devices, and software are all sold separately.

These contact point arms are required for pitch diameter inspection. Threaded shank contact point arms are available and require threaded shank contact points for use. Sold separately from gage as a set of 2. Specify straight or threaded shank contact point arms when ordering. Contact points are not included.
