Fasteners Workbench

Introduction
Usage is pretty straightforward:
 * 1) Install the Fasteners Workbench via the Addon Manager
 * 2) Start a new document in FreeCAD. Select the Fasteners workbench from the drop-down list.
 * 3) A series of screws will show on the toolbar.

Simple Usage: Clicking on any of the screws will create this screw in the origin position with default size. To change size/length select the newly created screw, then go to the data tab in the property panel, there you can change diameter and length.
