A headed and externally threaded fastener designed to be paired with a nut
Flats from finger tight
Also known as working position. The configuration of the machine when working in the
field.
A reference position in which the given sealing surfaces or components are making
contact with each other. The fitting has been tightened by hand to a point where the
fitting is no longer loose and cannot be tightened further by hand
Joint Industrial Council: A standards body that developed standard sizing and shape for
the original 37° flared fitting
Not applicable
National Pipe Thread: A style of fitting used for low-pressure port openings. Threads on
NPT fittings are uniquely tapered for an interference fit
An internally threaded fastener designed to be paired with a bolt
O-ring boss: A style of fitting commonly used in port openings on manifolds, pumps,

Tall end divider
An axial load placed on a bolt or screw, usually measured in Newtons (N) or pounds (lb.).
This term can also be used to describe the force a belt exerts on a pulley or sprocket
Turns from finger tight
The product of a force * the length of a lever arm, usually measured in Newton-meters
(Nm), foot-pounds (lbf∙ft), or inch-pounds (lbf∙in)
A tightening procedure in which a fitting is assembled to a specified tightness (usually
finger tight) and then the nut is turned farther by a specified number of degrees until it
achieves its final position
The relationship between the assembly torque applied to a piece of hardware and the
axial load it induces in a bolt or screw
The configuration of the machine when it is being transported between fields.
A thin cylinder with a hole or a slot located in the center, used as a spacer, a load
distribution element, or a locking mechanism
