Product Description

0.5TH Series SMR Adapters

Fits 1/8″ – 3/8″ and 4mm – 10mm diameter holes

The 0.5TH series of magnetic adapters provide nests (for 1/2″ diameter SMRs) which mount in holes having diameters from 1/8″ – 3/8″, and from 4mm to 10mm.  Shank diameters are held to very close tolerances for precision slip fits.  The adapter holds the centerpoint of a 0.5″ diameter SMR on centerline of the shank to a tolerance of ±0.0005″ (0.013mm).  Shank diameters are held to very close tolerances for precision slip fits.  Various diameters and offsets are available – see table below for descriptions and part numbers.
 
Choose any “A” value from the table below, and pair with any “B” value below right to create the item number for the product that you want. For example, 0.5TH-25MM-.375.
