Abstract
A nut is a hardware fastener with a threaded hole. Nuts are used with bolts to secure two objects together. Bolts go through two pieces of material. Bolts keep the pieces of material from separating. Bolts can keep two pieces from sliding against one another. Bolts connect objects together. Nuts stabilize the bolts. Nuts loosen over time. Washers are used with nuts to help keep them tight. Lock washers prevent a nut from loosening. Flat washers prevent the material from cracking from the pressure. However, occasionally, nuts must be tightened. Nuts are tightened with a wrench and a screwdriver. Loose nuts can cause stretchers and operating chairs to wobble. Very loose nuts can cause the bolts to fall out and the device to come apart.
