Workshop 4 10/11/16

Screw- goes thinner towards the end and pointy, doesn’t stick out the other side of the wood so you have to make sure you get the correct size.

Bolt- it is like a screw but has a flat end, comes out the other side of the piece of wood and a knut is screwed onto it.

Knut- it screws onto the end of the bolt to keep the bolt in place.

Washer- it is like a guard in between the knut and the piece of wood to stop the knut from damaging the material.

There are different types of screw and bolts you can get that totally change the look of the fitting, there are:

  • Pan head- has a flat head and sits on top of the material.
  • Counter sink- sinks into the hole so that the fitting can not be felt above the surface.
  • Slot head- a normal fitting but has a slot in the top of it, has a slot screwdriver needed for it as well.
  • Allen head- you can get at a counter sink or a button head, both have an allen key that goes with them.
  • Cross head- has a cross in the stop of it which has the same type of screw driver.
  • Pop rivet- has a shaft and a ball that cant be took apart easily to change. Needs pop rivet pliers to put the fittings in place.
  • Tap- makes a mark on the inside by cutting the thread inside, makes it into a knut for the bolt.

Apoxy resin glue- sticks anything together but isn’t really used on wood.

PVA wood glue- sticks wood together but doesn’t stick any other materially together as it will just peel off the material.
