How is a bolt made?

We don’t know, we just sell the things

In all seriousness, we really don’t know.

All joking aside,

What is tensile strength?

Queen wrote a famous song about this called “Under tension”….actually, no they didn’t. That was under pressure which is completely different to what we are talking about here. Tensile strength is really the complete opposite to what we think of when we talk about pressure. When most people think of pressure they have in mind a force that is bearing down on something whereas tensile pressure/stress is when…..

we could literally go throught this wikipedia article and use it to make jokes: https://en.wikipedia.org/wiki/Ultimate_tensile_strength

Fastener coatings and their applications

We have a lot of different coatings of fasteners, but what do they all mean to you?

What is shear strength?

Let us begin with the wikipedia entry, it pads out the content nicely…

In engineering, shear strength is the strength of a material or component against the type of yield or structural failure when the material or component fails in shear. A shear load is a force that tends to produce a sliding failure on a material along a plane that is parallel to the direction of the force. When a paper is cut with scissors, the paper fails in shear.

So, while tensile strength (link to the tensile strength blog post) relates to the amount of force that a fastener can take…………

What is the difference between a bolt and a screw?

It seems pretty obvious, right? A bolt is something that you do up with spanners or wrenches and a screw is something that needs a screwdriver. Well, like everything else in the world, the answer is not so simple as that…..
