[Mark IV]

We see many people have a complete lack of understanding of "thread length vs. grip length". While the local hardware store is handy, they likely do not have the proper grip length available in the size/strength needed for applications such as halfshafts, etc. We have I.D.' the needed hardware and carry an inventory from Aircraft Spruce for our internal needs. The AN screws and nuts (and a 'bolt' is a 'screw' until a nut is installed....) are also less expensive than the local ironmonger's pricing. The AN washers are also far superior to the thicker, softer washers from the hardware assortment.
