Tools . . .
there's
a
tool
to
avoid
these
tight fits
!
aha!
there
you
are!
i thought i
was stuck here
forever
!
epairmen, if you have trouble identifying bolt sizes and thread pitches, the
Army has the tool for you: a combination bolt sizer/thread pitch gauge.
The tool will not only help you pick the right wrench for each job, but also
help you identify a fastener for a quick fix.
The pocket-sized tool comes in both standard and metric models. The standard
model measures bolt diameters from
1
/
4
inch to one inch in
1
/
16
-
in increments. The metric version starts at five millimeters
and runs to 24 millimeters. Both models
measure thread pitch in millimeters from
0.8 to 3. Both tools also tell you what
wrench size you need. A guide on the back
of both gauges lists the bolt grade symbols.
The gauge is being added to the following tool kits: Gen-
eral Mechanics, Bradley Turret Mechanics, and the Artillery
and Turret Mechanics.
Order the standard gauge with NSN 5210-01-455-2936, and the metric with
NSN 5210-01-455-2937. Each costs less than $33.
Except in emergency situations,
never substitute bolts for the ones called
for in your equipment TMs.
That’s asking for trouble. The wrong bolt can snap
and cause serious damage to your equipment and maybe you.
echanics, the magnetic retrieving tool, NSN 5120-00-545-4268, in the general
mechanic’s tool kit is handy for recovering small items that fall into hard-to-
reach places.
Unfortunately, the retrieving tool is too bulky to reach into
very
small holes
and, even with a flashlight, you usually can’t see what you’re trying to retrieve.
Take heart. The new inspection and parts retrieval tool kit, NSN 5180-01-452-
6076, is coming to your rescue.
The kit includes a 10-in flexible light shaft that passes through openings as
small as
1
/
4
inch. A plastic extension wand extends the reach to 24 inches and
doubles as a protective cover for the light shaft.
An attachable magnet lets you retrieve small parts while a clip-on magnetic
mounting device allows hands-free use of the tool. A separate penlight, attach-
able reflector, and carrying case complete the kit.
Use Appendix A of CTA 50-970 as your ordering authority.
