Some may call this drawings Blueprints, In Manufacturing Blueprints are copies of these.
Technical Drawing
A hole that passes completely through a part
Through Hole
The grade of a fastener can quickly be determined by adding this # to the number of tick marks on the head
+ 2
This is A flat plane that is perpendicular to the direction of a measurement
Reference Plane
12 inches is also called a
foot
These are the 3 methods used to create technical drawings
Sketching, Instrument, Computer-Aided Drafting
This drawing view represents the internal features of a part by cutting it into pieces so that the inside of the part can be drawn as object lines
Sectional View
This part of the fastener protects the threads from being damaged
Shank
Depth, Width, Height and diameter are all types of this
physical dimension
3 feet is also called
a yard
This is a form of free hand drawing that does not use any special tools
Sketching
The plane that divides an object so that the sectional view can be shown.
Cutting Plane
This is attached to a bolt to keep it from falling out of a part.
Nut
Holes are measured using this
A millimeter is used in this measure system
SI Metric
These drawings are created using rulers,templates, squares and other specialized tools
Instrument drawings
ANSI stands for
American National Standards Institute
Washer
Every dimensional measurement has two parts, they are:
a # and a unit of measure
This is a dimensional measuring device made from a strip of steel
Machinist's rule
This type of drawing is done with a computer
Computer-aided drafting
The part of the fastener that a tool grips to to turn the fastener
Head
These threads are on the outside of the fastener as seen on a bolt or screw
External
The system of measure used around the world
SI Metric System
This is the most common measuring instrument in manufacturing because it can be easily carried in a pocket and provides quick measurement
Machinist's rule
