In metallurgy, stainless steel, also known as inox steel or inox from French "inoxydable", is a steel alloy with a minimum of 10.5%[1] chromium content by mass.Stainless steel does not readily corrode, rust or stain with water as ordinary steel does, but despite the name it is not fully stain-proof, most notably under low-oxygen, high-salinity, or poor-circulation environments.[2] There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties of steel and resistance to corrosion are required.Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by forming more iron oxide, and due to the greater volume of the iron oxide this tends to flake and fall away. Stainless steels contain sufficient chromium to form a passive film of chromium oxide, which prevents further surface corrosion by blocking oxygen diffusion to the steel surface and blocks corrosion from spreading into the metal's internal structure, and due to the similar size of the steel and oxide ions they bond very strongly and remain attached to the surface.[3]Passivation only occurs if the proportion of chromium is high enough and oxygen is present.

We manufacture a wide range of Bolts And Nuts as per IS :1363-92. A screw, or bolt, is a type of fastener characterized by a helical ridge, known as an external thread or just thread, wrapped around a cylinder. Some screw threads are designed to mate with a complementary thread, known as an internal thread, often in the form of a nut or an object that has the internal thread formed into it. Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common uses of screws are to hold objects together and to position objects. A nut is a type of hardware fastener with a threaded hole. Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads' friction, a slight stretch of the bolt, and compression of the parts. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: Adhesives, safety pins or lockwire, nylon inserts, or slightly oval-shaped threads. Fabricated from quality metal, our Bolts And Nuts are well-acclaimed for their superior quality and durability. These Bolts And Nuts are available in different specifications to meet the requirements of the clients. Features : Dimensionally accurateDurableCorrosion resistantSuperior quality

Permanently captivates into sheets as thin as.040" 11.02 mm and greater. Replaces loose hardware Available with jacking feature or axial float feature. Appropriate for close centerline-to-edge applications RoHS compliant Type SCB'"' Spinning Clinch Bolt is a one piece fastener that installs by simply pressing it into a properly sized hole. The controlled clinching action permanently captivates the screw in the panel yet still leaves it to spin freely in the sheet. This allows quick attachment of mating hardware, eliminating much of the need for loose fasteners, such as screws and retaining clips or washers. or expensive multi-component fastener assemblies.   The Spinning Clinch Bolt can also be used with the PEM Type N10 receptacle nut (see PEM Bulletin PF) and with the PEM Type RAS R'ANGLEg fastener .         Part Number Designation         All dimensions are in inches     All dimensions are in millimeters           Features :  Installation   Punch or drill properly sized mounting hole in sheet Place the fastener through mounting hole and into anvil. A flat or recessed punch can be used With punch and anvil surfaces parallel, apply squeezing force to the top of the screw head and the underside of the sheet material. The squeezing action forces the shoulder of the screw into the sheet, displacing sheet material, causing it to fill the void under the head and shoulder of the screw       All dimensions are in inches     All dimensions are in millimeters     Performanes Data

Through Bolt for push through installation. The fasteners is hammered into the drilled hole upto the anchors length (minus the height of nut.) When the nut is tightened, the tappered bolt is pulled into the safety wedge clip and expands it. The safety wedge clip is very reliable for anchoring and expands & takes grip in the wall.
