____ are useful for holding parts square and steady during layout operations.

Angle plates

____ are used to scribe lines parallel to the edge of material.

Hermaphrodite calipers

____ are simply bars with opposite sides that are parallel within very close tolerances.

Parallels

____ are used to lay out circles or arcs that are too large for dividers.

Trammels

After layout, the ____ punch can be used to enlarge the prick punch mark to aid in drilling operations.

center

The ____ is used to find the center of a cylindrical part.

center head

The ____ is used to draw circles, radii, and arcs.

divider

The solution to being able to see layout lines on rought, hard, or shiny materials is to coat the material with layout ____.

fluid

The ____ gage is used with a surface plate to measure and mark off horizontal lines in precision layout work.

height

The advantage of the ____ protractor is that it is smaller and flatter, and this can enable angle layout in places that other protractors cannot.

plain

The ____ punch can be used to mark the intersections of lines that locate the center points of circles or arcs.

prick

The most common tool used to mark straight layout lines is the ____.

scriber

The ____ gage is made up of a base and a scriber mounted on a spindle that can be adjusted to different positions by a swivel bolt and fine adjustment screw.

surface

The ____ plate provides a reference plane for layout just as it does for measurement tasks.

surface

The____ protractor can be used to lay out angles with an accuracy of 5 minutes (1/12 of a degree).
