Cage Nuts Specifications and Its Applications


Introduction to cage Nuts

A cage nut is used on a rack that has square mounting holes. You would use a cage nut when you need to mount a product in your rack that requires a threaded hole. A cage nut is nothing more than a square nut that has threaded holes wrapped in a piece of spring steel designed like a cage. This spring steel has two flanges that when pressed together allow the cage nut to be inserted into the square hole and simply clip in. When this done you now have a square hole that is threaded. The nut is typically loose in the cage to allow for adjustments when installing the screw.

Cage nuts combine the classic elastic properties of fasteners used for assembly with the strength of multi-threaded steel nuts. Cage nuts are designed to be used in any kind of assembly including blind assemblies and are particularly common in equipment racks. They can be fastened within their housing using bolts and subjected to considerable tightening torque or axial forces. No special tools or specialized fitters are required to mount these nuts. Once mounted in the rectangular hole the cage stays in place while the captive nut can move within the cage to permit assembly.

What are cage nuts used for?

Cage nuts are great for protecting your equipment from stripped threads and allow for convenient mounting of your server rack equipment. A cage nut houses a standard nut in a cage with a spring. The cage has two wings that can be pinched together to allow the cage nut to be inserted into a square hole.

Design of Stainless-Steel Cage nuts

Stainless Steel Cage Nuts mainly has a wide variety of designs. Depending on the use of the nut the shape and other features are designed. The purpose of these designs is that the nuts are useful for the bolts that will be used to tighten them. For instance, in some cases, the square nuts are used to tighten the parts with the square bolts. Each nuts fastener has a different specification and design. Each nuts fastener also has a different use for which they are designed

HEX NUTS AND ITS SPECIFICATION

Image
v   What are Hex Nuts? One of the most common nuts available are the Hex nuts that are used with anchors, bolts, screws, studs or any other fastener which has machine screw threads. This Nuts are widely used for industrial and commercial use. Hex, as the name suggests, is short-form off Hexagon. Hex nuts have six sides in the shape of a Hexagon. Hex Full Nuts, Finished Hex Nuts are some of the names given to Hex Nuts. Hex Nuts are required for fastening purpose. Though, the design of a hex nuts is simple but they are created to deliver high end efficiency and Performance. The size of hex Nuts, typically varies from ¼” to about 2 ½” and are available in different Strength Grades. The Grades are given on the basis of Strength and cost of the nuts.   Stainless steel hex nuts and bolts/screws used together are susceptible to thread galling and seizing. While it may not be completely preventable, it can be substantially reduced. A thread lubricant is the most effective m

Manufacturing Process for Fasteners in 7 steps

Image
A fastener is a hardware component used universally for fixing joints with two or more things non-permanently. In general, fasteners are used to create non-permanent joints i.e. joints that can be removed or dismantled without harming or damaging the joining components.  Welding is an example of creating permanent joints. Fastener holds the joints of fixtures form holding the chairs & tables to automobile parts. Applications of fasteners are very diverse in the range from regularly used items like boxes, envelope where fasteners are used for closing them to hi- tech gazebos & special-purpose closing devices like the bread clip etc. Fasteners exporter in Germany will discuss the manufacturing process of fasteners. Step-1: Raw material inspection & storage Raw material for the bolt to be decided upon the designer based upon where it is to be used. Material to be used to be inspected & then proper storage location to be identified in order to avoid rust forma

Different types of Fasteners

Image
Bolts : Bolts are used to make a bolted joint. A bolted joint is created by a bolt and a nut together. Where a Nut is used to tighten the grip between the flange or such product where bolt is used. Basically bolts are used for the assembly of two unthreaded components with the help of a nut.  Nuts : Nuts are a type of Fasteners that has a hole in it. The hole in the Nuts is always threaded. The nut is paired with the bolt which is its pairing partner. The Nuts are always used with the pairing Bolts to tighten. Click here to know more about nuts manufacturers in Canada . Screws : Screws is a fastener that is similar to the bolts in many ways. The Screws are made of metals and characterized by helical ridge. Screws is also known as male thread. Screws are used to fasten the materials by digging in and welding into a material. Screws don't require nuts to tighten the screws.  Thread Rods : Threaded Rods is a fastener that is also known as 'Studs'. The Thr
