MICROMETER HEADS AND
BENCH MICROMETERS
The following pages show the full line of
Starrett standard micrometer heads and
bench micrometers that have been
designed and developed over the years
working with the needs of our
customers. The micrometer heads are
invaluable for use on electronic
equipment, machine tools, fixtures,
special gaging and other equipment
where precise movement and
adjustment are required.
Special features are described with each
tool, but all of these tools have these
features that benefit the user.
◆ Starrett satin chrome finish – no glare
– resists rust on all reading surfaces
◆ Advanced sleeve design with
staggered lines and distinct figures
for precise and easy readability
◆ Quick-reading figures on all inch
reading tools
◆ Extremely hard and stable one-piece
spindle (the heart of our accuracy and
long life)
◆ Micro-lapped measuring face for
flatness and squareness
◆ Quick and easy adjustment
◆ Starrett workmanship
Standard heads and
bench model.
Special Heads
In addition to standard micrometer
heads, Starrett has also designed and
manufactured many special types of
micrometer heads for widely diversified
applications requiring micrometer
accuracy in settings and adjustments.
These special heads are designed to
exact specifications for specialized
usage with wavemeters and other
equipment in the electronics industry,
machine tools, fixtures, special gages,
tools, and all special mountings. They
can be furnished to suit your particular
requirements in a wide choice of sizes,
range and graduations.
We design and build to your special
need, so if you don’t see what you want,
please ask for it.

spindles
No. 261L 0-1/2
No. 261ML 0-13mm
Because the spindle does not rotate, these
tools are useful in driving positioning tables
directly without an intermediate connecting
device. They are also useful in gaging jobs
where scratches on the work surface
cannot be tolerated or where there is risk
of distortion when spindle meets work – as
in measuring soft or elastic materials.
Spindle wear is also reduced since there
is no rotational friction as its face contacts
the work.

No. 262 Series 0-1
No. 262M Series 0-25mm
Because the spindle does not rotate, this
tool is useful in driving positioning tables
directly without an intermediate connecting
device. It is also useful in gaging jobs
where scratches on the work surface
cannot be tolerated, or where there is risk
of distortion when spindle meets work – as
in measuring soft or elastic materials.
Spindle wear is also reduced, since there is
no rotational friction when its face contacts
the work.

MICROMETER HEADS
Direct-Reading, Large
Micrometer Heads
0-1⬙ / 25mm Ranges
0-2⬙ / 50mm Ranges
These large micrometer heads are
designed for use with electronic equipment
requiring ultra-fine adjustment for machine
tools, fixtures, special gages and tools,
special mountings, or wherever micrometer
accuracy in setting and adjustment is
required.
The micrometer heads with 2 1/16⬙
(52mm) thimble diameter have widely
spaced .0001⬙ or 0.002mm graduations.
The micrometer heads with 4 1/16⬙
(103mm) thimble diameter have
graduations up to .000050⬙ or 0.001mm.
Another highly useful feature is the spindle
adjustment, which permits adjusting the
spindle length approximately ±1/16⬙
(1.5mm). If the spindle is to be located
against a definite stop and a different zero
position is required, first loosen the cap
screw in the end of the thimble, position the
spindle to the desired location, then holding
the spindle in position, rotate the thimble to
zero and retighten the cap screw. In
achieving this adjustable feature, we have
still retained our positive taper-lock large
thimble bearing.
Readability, Accuracy and
Long-Life Features:
◆ All graduations are direct reading – no
vernier lines to match
◆ All reading surfaces have Starrett satin
chrome finish as the no-glare
background for the sharp lines and
figures
◆ All graduations on sleeves and thimbles
have advanced styling with staggered
graduations for easy reading
◆ The spindle is carbide faced for long life
◆ Thimble and sleeve are made of
aluminum to reduce weight
◆ Furnished with a speeder (not a ratchet)
for quicker adjustment
◆ Extremely hard and stable one-piece
spindle for accuracy and long-life
◆ Micro-lapped measuring face for
flatness and squareness
◆ Quick and easy adjustment
◆ Starrett workmanship
(Top) No. T465XSP-1 (inch model) and (bottom) No. T468XSP-1 (inch model) with
double figures in red and black on sleeve and thimble for reading both ways.
No. 465 Series 0-2⬙
No. 465M Series 0-50mm
No. 468 Series 0-2⬙
No. 468M Series 0-50mm
The No. 468 Series micrometer heads are
exactly the same as the No. 465 Series,
except that they have double figures in red
and black on the sleeve and thimble,
permitting reading both ways with the
spindle moving in either direction. This
feature is invaluable on many instruments
and microwave applications.
These heads have 2 1/16⬙ (52mm) thimble
diameter with widely spaced .0001⬙ or
0.002mm graduations for direct reading.
