Stainless Steel 304 Plain Color Serrated Hex Flange Nuts for Pipe Connections​

1. Product Description

Serrated flange nuts are hex flange nuts with a serrated bearing surface. The nut turns freely until the serrations contact and displace material on the mating surface as the nut is tightened; less torque is needed to install than remove because the gripping action of the serrations create a ratchet-type locking feature that is resistant to vibration. If the mating surface is painted or plated, corrosion can occur if the nut's wiping action removes the surface treatment. The protruding circular flange increases the bearing surface of the nut allowing it to be used with irregular and oversized holes. Used in commercial and industrial applications, serrated flange nuts are also called:serrated face lock nuts, serrated tooth nuts, spin lock nuts, whiz lock nuts.

Because the serrations must contact the mating surface to "lock", serrated flange nuts are not used with flat or lock washers.

Threads are standard right-hand and Unified inch coarse series (UNC, Unified National Coarse) or Unified inch fine (UNF, Unified National Fine).

Serrated flange nut size refers to its nominal thread diameter. Typically, sizes range from about #6 to 5/8". Sizes less than 1/4" are listed as a number size (the larger the number the larger the size) while sizes that are 1/4" and larger are specified in inches, usually fractional rather than decimal.

Nut width and thickness vary with the size of the serrated flange nut.

the flanged nut is much less prone to damaging the soft metal surface than a traditional nut.

Another popular reason for using a hex flange nut is the ability to place the nut into a socket wrench and then reach into hard-to-access areas without dropping the nut. The flange sits tightly against the edge of the socket wrench and prohibits the nut from sinking deeply into the socket. The socket can be used as an extension of the user's arm in order to start the nut onto the bolt. Combined with a magnetic socket wrench, a hex flange nut is nearly impossible to drop out of a socket wrench.

3. Application

The flange nuts are available in most common metal types including brass, stainless steel and titanium. Course and fine thread nuts are also available in the flanged design, making the fastener a viable option for most fastening requirements. The serrated bottom of the locking flange nut design is a popular choice with electronics fasteners. The serrated flange bites and holds electrical fasteners in place. When used on a fragile surface, such as aluminum, the flanged nut is much less prone to damaging the soft metal surface than a traditional nut.

Often used when a separate locking nut and washer would be difficult to employ, the hex flange nut allows the user to start the fastener with one hand even when in a difficult location to access. Once started, the hex flange nut is easily tightened into place using a socket wrench and an air tool. Most assembly line manufacturing jobs enlist the aid of hex flange nuts to speed the assembly process along the line. Workers are much faster placing a single fastener onto a bolt or stud than compared to placing a locking washer and a nut onto a comparable bolt or stud. This makes the line run smoother and requires less stops due to missed fasteners or cross-threaded fasteners, which are nuts that are forced crookedly onto bolts as a worker rushes to stay caught up with the assembly line.
