Quality Inspection for Round Head Hex Bolt - Stainless Steel Serrated Flange Nuts – Chuanyi Detail:

Description

flange 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. Flange is which means they have flange bottom. Metric Flange Nuts resemble and are frequently used with Flange Bolts. They share the same flange that flares to a diameter that’s larger than the hex section and machine screw threads that are either coarse or fine; the bearing surface can be smooth or serrated. Use serrated to resist loosening. Steel strength grades include Class 8 and 10 with a plain or zinc plated finish.

To ensure full thread engagement with the flange nuts, 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

flange 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 flange 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 bolts are used in small engines. Grade 8.8 10.9 or 12.9 bolts provide high tensile strength. One advantage nuts fasteners have over welds or rivets is that they allow for easy disassembly for repairs and maintenance.
