aluminum tubing.
Putty Knives/Scrapers - correct answer ✔✔ Step Hold the knife in one hand at an effective angle
to the work, and scrape the gasket off using smooth, even strokes.
Diagonal Cutters - correct answer ✔✔ are small pliers used to cut wire cotter pins, and other
items made of light material that are inaccessible with other types of cutters.
Tin Snips - correct answer ✔✔ They are used to cut light-gauge sheet metal where the shape,
position, or location prevents the use of power metal-cut- ting tools.
Red- handled aviation snips cut to the - correct answer ✔✔ Left
Green-handled aviation snips cut to the - correct answer ✔✔ Right
,Yellow-handled aviation snips cut a - correct answer ✔✔ straight line.
Dies - correct answer ✔✔ are used to cut external threads on bolts and rods.
Taper taps - correct answer ✔✔ are used when starting tapping operation or when tapping
through holes. They have a chamfer length of 8 to 10 threads.
Thread Gauges - correct answer ✔✔ also known as screw pitch gauges are used to measure the
pitch of threaded fasteners.
Sheave Gauges - correct answer ✔✔ Are used to measure the side wall wear of a belt sheave.
Packing Pullers - correct answer ✔✔ used remove packing mate- rial from valves, pumps, and
some motors.
Extractors - correct answer ✔✔ Use ____ if the screw or tap is broken near or below the surface
of the work
Spiral Screw Extractors - correct answer ✔✔ or easy-outs, are reverse- threaded to remove
right-hand threaded screws or bolts.
Portable grinders - correct answer ✔✔ Maintence craftworkers use ___ for beveling

angle from the handle.
Grinder accessories - correct answer ✔✔ When selecting a grinding wheel for a given job, two
factors must be considered. wheel must be suited to the material being ground, and the maxi-
mum rotational speed of the wheel must be rated higher than the rotational speed of the
grinder. correct wheel can be identified by referring to the manufacturer code stamped or
printed on the wheel.
Safty warning grinding - correct answer ✔✔ Always grind with the direction of the bevel and
position the wheel to the bevel, so that if it kicks off, it will kick off from you.
PIPE THREADING MACHINES - correct answer ✔✔ multipurpose power tools that center, hold,
and rotate pipe, conduit, or bolt stock while cutting, reaming, and threading operations are
performed.
Correct threads - correct answer ✔✔ If the threads are correct, you should be able to screw a
fitting three and a half revolu- tions by hand onto the new threads.
Thread classes - correct answer ✔✔ Classes each 3A other and by 3B the allow degrees of
minimum tolerance distinguished clearance and permitted.
Nominal size - correct answer ✔✔ Approximate diameter of the fastener.
buttress thread - correct answer ✔✔ One side of the thread cut square and the other cut at a
slant. It has great strength along the thread axis in one direction only. This thread form is used
to screw thin tubular parts together
Grade markings - correct answer ✔✔ Generally, the higher-quality steel fasteners have a greater
number of marks on the head.
