If you are as fastidious about your workstation as Martha Stewart is about her table setting, you always ensure that there is never a screw out of place or a wobbly chair at your desk. Framing fasteners are the vital connectors that keep materials and machinery secure. For example, when we commit to piecing together DYI Ikea furniture, we are scrupulous in employing the myriad bits and pieces as directed. While we may fret and fume during the assembly process, nuts and bolts ensure the end product looks and functions as advertised.
Bolt vs. Screw
Bolts are externally threaded fasteners installed with the use of proper nuts that are fitted using torque. Bolts are typically used to couple unthreaded objects. The threads spiraling on the circular surface of the bolts provide exceptionally sturdy bonds in conjunction with a nut.
Screws are also externally threaded fasteners. They can be inserted into premade holes or perforated surfaces and sometimes create threads during installation.
