DISCUSSION BOARD - FASTENERS:
A fastener is "a hardware device that mechanically joins or affixes two or more objects together. In general, fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components." There are several different key parts of fastenings with different counterparts. Starting with the screw section There are wood screws, sheet metal screws, hex bolts, and carriage bolts. These are the main part of the fastening that goes through the actual object. another category id the drive types such as Phillips, flat head, and (Socked, hex, or Allen.) These help you decide what tool to use drive your bolt or screw through the object. The next category is the washers. A washer helps protect the object you are fastening from the bolt or screw or if need be used as a makeshift spacer. The last common type of spacer is the nut. Two examples of this are the Hex and wing nuts. These are the other ends of strictly bolts, (Not screws) they help ensure that the bolt will not fall or slide out of the object and apply pressure to the fastening. I have satisfied this course when I was working on my wheelchair design, I had to make a thin Hex nut to fasten to a bolt to hold the swivel wheels to the frame. Future working goals for this standard are to make a working Nylon Insert Lock-nut. I still am a little unfamiliar with the point of J-Bolts.
