This joint is quick to make with production line machinery and so is a very common joint in factory-made furniture. Cross dowel joint: A threaded metal dowel is inserted into a drilled slot. A screw is then inserted through an ...
Hollow spring pins provide a weaker shear strength than a solid dowel pin, and the strength may be varied by varying the wall thickness. This limited shear strength specification is designed to sustain normal operation, but then give way in the event of excessive shaft torque, thus protecting the rest of the machine from damage.

Use the text button to add text to your diagram. The next 9 buttons are used to add shapes and lines to the diagram. Experiment with them: they are pretty much self explanatory. Below is a drop down list that allows you to choose from several groups of special objects that can be used in your diagram.
Pins have extra sharp tips for penetrating thick iron-on patches; their size and length also make them suitable for quilting; they have glass heads that will not melt if pressed in an iron. Quilting pins: 30 (0.6 mm) 1 + 7 ⁄ 8 in (48 mm) Quilting pins are exceptionally long and often have glass heads. Silk pins: 0.5 mm: 1 + 7 ⁄ 16 in (37 mm)
A spring pin (also called tension pin or roll pin) is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the diameter of the hole they are intended for, and a chamfer on either one or both ends to facilitate starting the pin into the hole.
