Product Introduction

Hex nuts are one of the most common nuts available and are used with anchors, bolts, screws, studs, threaded rods and on any other fastener that has machine screw threads.Hex is short for hexagon, which means they have six sides.Hex n uts are almost always used in conjunction with a mating bolt to fasten multiple parts together.The two partners are kept together by a combination of their threads' friction (with slight elastic deformation), a slight stretching of the bolt, and compression of the parts to be held together.

  • carbon steel hex nut

     

  • zinc plated hex nut

     

  • coarse thread hex nut

     

To ensure full thread engagement with the hex nut, bolts/screws should be long enough to allow at least two full threads to extend beyond the nut face after tightening.Conversely, there should be two full threads exposed on the head side of the nut to make sure the nut can be properly tightened.

 Applications

Hex nuts can be used for many different applications that include fastening wood, steel, and other construction materials for projects such as docks, bridges, highway structures, and buildings.

 

 Black-oxide steel screws are mildly corrosion resistant in dry environments.Zinc-plated steel screws resist corrosion in wet environments.Black ultra-corrosion-resistant-coated steel screws resist chemicals and withstand 1,000 hours of salt spray .Coarse threads are the industry standard; choose these Hex nuts if you don’t know the threads per inch.Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.

 

The  Hex nuts is designed to fit a ratchet or spanner torque wrenches allowing you to tighten the  nuts to your exact specifications.Grade 2 bolts  tend to be used in construction for joining wood components.Grade 4.8 bolt s are used in small engines.Grade 8.8 10.9 or 12.9 bolt s provide high tensile strength.One advantage nuts  fasteners have over welds or rivets is that they allow for easy disassembly for repairs and maintenance.
