• Inch reading sets
• With finished wood case

These sets have been put together for your ordering convenience, but you
can mix and match other Starret test or back-plunger indicators and
attachments with the No. 657A Magnetic Base and Swivel Post Assembly to
suit your needs.

Universal Back-Plunger Dial Indicators is one of the
most versatile indicators available, and it is the “granddaddy” of them
all.

Over the years this tool has been improved by methods and materials
but the basic design is unchanged.

The design is older than most of you
and has withstood the test of time and beaten all challengers because
it is: Accurate and reliable, simple to operate, rugged, with few moving
parts, smooth in operation, inexpensive-the best indicator value you
can buy.

Snug Complete PT18718 Post hole has a 5/16″ diameter and
3/32-1/4″ holding capacity.

Can be used on our no. 252 height transfer
gauge, nos. 57 and 257A and B surface gauges, on no. 657A magnetic base
and swivel post assembly.
