Cage nut
A cage nut or caged nut( also called a captive or clip nut) consists of a( usually square) nut in a spring steel cage which wraps around the nut.
The cage has two wings that when compressed allow the cage to be inserted into the square holes, for example, in the mounting rails of equipment racks.
When the wings are released, they hold the nut in position behind the hole.
Cage nuts conforming to this description were patented in 1952 and 1953.
This design requires insertion tools to install the cage nut into the hole.
Newer designs featuring a squeeze- and- release tab allow for tool- less installation.
The square- hole cage nut can be used wherever a square hole can be punched.
An older type of captive- nut uses a spring clip that holds the nut and slides on the edge of a thin sheet.
While this type of cage nut can only position the nut a fixed distance from the edge of a thin plate, it works equally well with square and round holes.
A patent for such a nut was granted in 1946.
Using cage nuts provides several benefits over threaded holes.
It permits a range of choice of nut and bolts size( e.g. metric vs imperial) in the field, long after the equipment has been manufactured.
Second, if a screw is over- tightened, the nut can be replaced, unlike a pre-threaded hole, where a hole with stripped threads becomes unusable.
Third, cage nuts are easy to use on materials too thin or soft to be threaded.
The nut is usually slightly loose in the cage to allow for minor adjustments in alignment.
This reduces the likelihood that the threads will be stripped during equipment installation and removal.
The dimensions of the spring steel clip determines thickness of the panel to which the nut may be clipped.
In the case of square- hole cage nuts, the clip dimensions determine the range of hole sizes to which the clip will securely hold the nut.
In the case of slide- on cage nuts, the clip dimensions determine the distance from the panel edge to the hole.
Serrated face nut
A serrated face nut is a locknut with ridges on the face of the nut that bite into the surface it is tightened against.
The serrations are angled such that they keep the nut from rotating in the direction that would loosen the nut.
Due to the serrations they can not be used with a washer or on surfaces that can not be scratched.
Sometimes both faces of the nut are serrated, permitting either side to lock.
The Nut Farm
The Nut Farm is a 1935 American film directed by Melville W. Brown.
The Nut (1921 film)
The Nut is a 1921 American silent film comedy directed by Theodore Reed.
Fairbanks biographer Jeffrey Vance writes, "Admittedly a minor work, "The Nut" is frequently dismissed in critical assessments of Fairbanks's career.
This is unfortunate, for it contains some fascinating sequences and reveals much about the actor-producer's state of mind at the time it was made."
Vance also notes, "The picture is like a chaotic funhouse, filled with magical masquerades, illusions, and gimmicks of great momentary amusement."

Castellated nut
A castellated nut, sometimes referred to as a castle nut, is a nut with slots( notches) cut into one end.
The name comes from the nut ’s resemblance to the crenellated parapet of a medieval castle.
Castellated nuts are sometimes referred to incorrectly as castigated nuts.
While castellated nuts are often referred to as slotted nuts, from a technical perspective, slotted nuts differ slightly from castellated nuts.
Castellated nuts are formed with a round section at the top where the slots are located.
Slotted nuts do not have this rounded modification.
The flat sides of slotted nuts extend fully from the top to the bottom of the nut.
Both castellated and slotted nuts are designed to use a pin( usually a cotter pin) that fits through the slots and through a hole in the screw to which the nut is attached.
This pin prevents the nut from turning and loosening.
Compared with slotted nuts, castellated nuts allow the cotter pin to be confined closer to the margins of the nut itself, providing added secureness.
The bolt has one or two holes drilled through its threaded end.
The nut is torqued properly and then, if the slot is not aligned with the hole in the fastener, the nut is rotated forward to the nearest slot.
The nut is then secured with a split pin/ cotter pin, R-clip or safety wire.
It is a positive locking device.
Castellated nuts are used in low- torque applications, such as holding a wheel bearing in place.
List of Fred and Anne Jarvis Award winners
Named after former National Union of Teachers( NUT) General Secretary Fred Jarvis and his late wife, the Fred and Anne Jarvis Award was established in 2007 and first awarded in 2008.
It was originally presented annually by the NUT to individuals outside the NUT who campaign on education and related issues but in 2017 the award was made to an NUT member.
From 2019 the award has been presented by the National Education Union, which has succeeded the NUT.
