Siddhagiri Metals and Tubes supplies a comprehensive range of Monel 400 Fasteners, catering for demands of a wide range of industries. Our entire inventory of Alloy 400 Fasteners is available in multiple sizes and types. We also manufacture fabricated items for special applications. Monel Alloy Fasteners are intended mainly for use in high-temperature, seawater and acidic environments.

A Fastener is a device that mechanically joins two or more components together. Monel Fasteners are used to create non-permanent joints; that is, joints that can be removed or dismantled without damaging the joining components. We are a well known supplier of Monel bolts, Monel nuts, Monel screws, Monel studs and Monel washers. Monel 400 Fasteners are widely used in almost all types of industries. These Monel 400 Fasteners are available in various shapes, sizes and designs. Fasteners manufactured by Siddhagiri Metals and Tubes conform to dimension standards like DIN 933, ISO 4017, DIN 931, ISO 4014, DIN 982, DIN 985, DIN 912, ISO 7380, DIN 7991, DIN 125, ISO 7379, DIN 127, DIN 1481, DIN 975, DIN 6923, DIN 934, DIN 7984. Our stock of fasteners range includes sizes 1/4" NB to 4" NB in Class 2000, 3000, 6000 and 9000. There are a variety of applications of fasteners in various industries such as automobiles, aircraft, appliances, agricultural machinery, commercial construction, and infrastructure. Fasteners can be divided into two main categories - non-permanent fasteners and permanent fasteners. Non-permanent fasteners (they enable parts to be assembled and disassembled repeatedly) can further be divided into two groups: General fasteners and Threaded fasteners. They are the most widely used type of non-permanent fasteners since they can easily be removed then reused.

Threaded Fasteners are the principal devices used for assembling components and they are usually grouped into three main categories: Threads can be either external or internal:
External Thread: External threads are on the outside of a member (such as the threads of bolts and screws). A chamfer on the end of the screw thread makes it easier to engage it into a hole or a nut. An external thread is usually cut using a die or a lathe.
Internal Thread: Internal threads are on the inside of a member (such as the threads of nuts and holes). Usually, threaded holes have a chamfer on the side from which the screw will enter to make its engagement easier. An internal thread is usually cut using a tap.

Monel Bolts: A bolt has a head on one end and threads on the other end and it is paired with a nut. Machine Bolt, Stove Bolt, J-Bolt, Hanger Bolt, U Bolt, Shoulder Bolt, Elevator Bolt, Hex Head Bolt, Carriage Bolt, Anchor Bolt, Eye Bolt are some of the types of bolts fasteners.

Monel Screws: Screws are used to join two mating parts together and similar to bolts, they have the head on one end and threads on the other end. However, screws usually have longer threads than bolts, also they can be made with slotted heads. Screws are further divided into two sub-categories; Cap Screws and Machine Screws. Machine screws are generally smaller in size than cap screws and they are used for screwing into thin materials.

Monel Setscrews: Setscrews are a special type of screws that usually does not have a head and they are used to prevent rotation or movement between parts (such as a shaft and a collar). A Setscrew is driven through one member such that it will apply a compressive force on the other member while a screw or a bolt clamps the two members together.

Monel Studs: A Stud is a rod that is threaded on both ends and joins two mating parts. A nut may be used on one end.

Monel Nuts: A Nut is the counterpart of a bolt. Bolts and nuts are used together to clamp two or more parts having unthreaded holes together. Our supply of Monel Nuts are Hex Nuts, Wing Nut, Castle Nut, Flex Lock Nut, High Nut, Coupling Nut, Cap Nut, Acorn Nut, Flange Lock Nut, Jam Nut, Flange Nut, Square Nut, Nylon Lock Nut, Slotted Nut, T-Nuts, Heavy Hex Nut.

Washers: Washers are commonly used under the heads of bolts and screws and they are used under nuts as well. The most common type of washers is the Flat Washer, where it is used to increase the bearing areas of the head, and protect the material finish during assembly. The use of washers also prevents the sharp corner of the hole into which the bolt or screw is being inserted from biting into bolt head fillet where that can cause the failure of the bolts during service. Our stock range of Monel washers are Lock Washer, Spring Washers, Dome Washer, Fender Washer, Tab Washers, Plain Washer, Flat Washer, Hexagonal Washer, Square Washer, Dome Tooth Washer, Split Washer, Countersunk Washer, Tooth Lock Washer, Dock Washer, Ogee Washer, Hex Washer.
