1.Product Description

 

Hex nuts and bolts, screws with the use of the connecting mechanical fastening effect. 1 of the most widely used type hexagon nuts, C-level nut for rough surface, on to less precision machinery, equipment or structures; A and B grade nuts for relatively smooth surface of high precision machine , equipment or structure. Type 2 hex nut thickness m thick, used often require frequent disassembly occasions. Hexagon thin nut m thickness thinner, used to be connected to parts of the surface of the space-constrained applications. Anodic oxidation and chemical into black oxide black, anodized black to be powered, the ultimate goal is to generate the metal surface oxide film is a dense black, to beautify the appearance, improve corrosion effect.

Hex nuts are six sided general purpose fasteners with internal screw threads.

The most common hexagonal fastener with internal threads that screws on to the shank of a bolt or a hex cap screw.

3.Application

 

In normal use, a nut-and-bolt joint holds together because the bolt is under a constant tensile stress called the preload. The preload pulls the nut threads against the bolt threads, and the nut face against the bearing surface, with a constant force, so that the nut cannot rotate without overcoming the friction between these surfaces. If the joint is subjected to vibration, however, the preload increases and decreases with each cycle of movement. If the minimum preload during the vibration cycle is not enough to hold the nut firmly in contact with the bolt and the bearing surface, then the nut is likely to become loose.
