Welcome back to Albany County Fasteners - Fasteners 101
I'm Bob and today we're going to talk about shoulder bolts.
Also, we're going to reveal the winner of the cool creations at the end of the video. Let's get started.
So I have here shoulder bolts. I have here 3/8" socket shoulder bolt
which is pretty much the most common shoulder bolt out there.
Shoulder bolts are measured by the shoulder.
So if you were to see listed a 5/8" by 2 inch shoulder bolt,
that would be indicating the diameter would be 5/8 of an inch okay
and the 2-inch would be the length from under the head to the end of the shoulder.
That does not include the threaded portion.
Shoulder bolts are always measured in that fashion. The threaded section, either you get this
shoulder bolt in two inches a half-inch five inches long,
the thread portion will always be the same in length.
So in this scenario here on a 5/8 bolt it's
approximately 3/4 of an inch in length for the thread.
When you have a 5/8 shoulder your threaded portion is going to be 1/8 less than the 5/8. In this case,
half-inch thirteen. Half-inch being the thread diameter and the 13 being the thread pitch.
On the 3/8, in this scenario,
again measure 3/8 by 2 inches long the 3/8 would be as far as the threaded portion will be
5/16-18 as you can see here typically a shoulder bolt or called stripper bolts, are used to create a pivot point.
They use these when you put in bearings on machines, many mechanical applications in which shoulder bolts are used.
Typically you would find them with a socket head that's fairly large, also, the heads are always knurled.
You can use the shoulder bolt with the flat washer along, if you want to use a lock washer
and then you put a finish nut on or you can use a nylon lock nut.
So you wouldn't have to use a lock washer or a regular finish nut.
That would be in lieu of the finish nut and lock washer. You can also purchase shoulder bolts
in hex head. They're available in several other heads
There are several different varieties of styles that you can get.
So I just wanted to demonstrate to you and show you the different shoulder bolts
