Fasteners are the pervasive and unseen force holding our China
Non-standard shaped bolts Suppliers industrial world together. Only gravity
can claim a greater responsibility for keeping things together. When one speaks
of fasteners, one refers to all manner of screws, bolts, anchors, Velcro,
threaded bars, and so on. Fasteners hold two or more objects in place, with the
aim of allowing zero movement. A fastener joins two things as one. You might
sometimes wonder: why don't people just build things as one piece in the first
place? Why use the middleman of fasteners? The answer is that not everything is
small enough to erect, ship, or otherwise manipulate. Without fasteners, there
would be no skyscrapers. There would be no cars. There would be no Velcro tennis
shoes or quick-release stage costumes.
There are many different types of fasteners, made of varying materials. The
most recognizable fastener is the screw. As everyone knows, it is comprised of a
head, a shank, and threads for both guiding the screw into place and for keeping
it in there. The head can take many forms, including those that allow the screw
to be removed after it has been inserted, and those that prevent people from
removing the screws at all. The lengths, widths, and pitches of the threads all
vary. (The pitch is the angle at which the thread is set; low pitches allow for
easier and more gradual insertions, while high pitches are better suited to
Most fasteners are made of metal, but there are many instances for which
plastic screws will do the trick, or when are just as powerful a material to
replace a metal screw. Plastic fasteners are non-conductive, and, in many cases,
Whatever kind of fastener you need, there is one out there for every kind of
job imaginable. Just think: humans are tool users, and fasteners are arguably
one of the single most vital tools in history. If there were no fasteners, you
probably wouldn't be alive today.

Early on in our Mexico experience, we still had not learned much
Spanish. In fact, when we arrived, our huge Spanish vocabulary consisted of
about two words: si and no.
We were in Villahermosa for about a month before we felt
comfortable in most situations and that was only because we were experiencing
full immersion learning of the language.
One big encouragement to learning the language is that we ate in
the hospital cafeteria three meals a day. Unfortunately, they did not eat at the
times that we expected meals. So, for the first couple of days we made it to
about one meal a day.
I can tell you that an empty stomach is a strong reason to learn
During that early time, one lady asked my wife if she could use
the baño. My wife, knowing that
baño means the bath, told her that
she could not use the baño until the
next day. However, the lady was asking to go to the bathroom. She was not really
interested in waiting until the next day!
While the local Mexicans were laughing at that, they told us about
a minister that had come over from Florida and had the church service while he
was there. He showed up late and told the people that he was muy embarasado for
showing up late. Unfortunately the words for embarrassed and pregnant are very
close. He had used the wrong one.
We asked a lot of people and nobody could tell us what his sermon
My father in law was driving down in Mexico as a tourist one time
when he suddenly was stopped by soldiers at a check point. The soldier came up
and forcefully asked him something in Spanish. My father in law was all
flustered and blurted out, "No speaka de English!" The soldier laughed and waved
The problems work the other way too.
I had a teacher in high school who was from Germany. He had been
taught English from the time he was in grade school. However, some of the
subtleties still escaped him.
When he first came to the United States he was asked to introduce
a speaker for some meeting. He told us that this lady was quite large. In fact
she was very large. She was also fairly important. Her reputation was of being
simply tremendous. So, he proceeded to introduce here like this: "I want to
present to you a lady who is simply enormous."
You might think that I am trying to tell you not to bother trying
to learn or speak a foreign language. However, nothing could be further from the
I am trying to tell you that along the way you may give other
people a good laugh. But it is a rare individual who will take offense at you
slaughtering their mother tongue.
And, you can take comfort in the fact that when you screw up, you
are certainly not alone.
