They are standard material specification for high tensile nuts and other internally threaded fasteners, made from carbon steel.
Coupling NutsExtension Nuts
Diameter
From /2" - Upto 2"
From M3 - Upto M68
They are elongated internally threaded nuts used to join two male threads. Coupling nuts are often used for joining threaded rods.
Durlock Nuts
Diameter
From M6 - Upto M20
They are high-grade hexagon flange nuts with a serrated mating surface that prevents any loosening from jarring or vibration.
Nylock Nuts
Nylock Nuts
Diameter
From 3/16" - Upto 1-1/2"
From M3 - Upto M39
It is an economic locking nut and ideal in applications where vibration or motion could loosen or undo the nut.
Prevailing Torque Nut
Prevailing Torque Nut
Diameter
From 1/4" - Upto 4"
From M3 - Upto M36
Prevailing Torque Lock nuts continue to resist loosening, even while sustaining substantial friction during assembly.
Scaffolding Wing NutShuttering Wing Nut
They are a type of nut that are characterized by the presence of two tabs. It consists of a metal piece with a threaded hole. To hold two or more objects together, they are used with a wing bolt or wing screw.
Square Nuts
Square Nuts
Diameter
From 1/4"- Upto 1-1/2"
From M4- Upto M16
They are four-sided nut that is designed for use with a square head bolt and flat washer.
Weld Nut
Diameter
From M4 - Upto M12
They come with small three leg projections which are used to weld the nut into the material. The projections also help if the host surface is uneven, but the nut has to be fixed flat on the surface. These nuts come with a pilot hole which allows for precision threading while being placed in the accurate location on the surface.
Wing Nut
Diameter
From M3 - Upto M12
They come with two flat and wide protrusions which make it easy for frequent adjustments which have to be made by hand. They are commonly adjusted without the help of tools, and for that reason, they are one of the most popular fasteners used for home improvements.
Dome Nut
Diameter
From M3 - Upto M30
This is mostly used to protect objects close to the ends of screws from scratches and structural injuries. It also reduces the effects of physical mishaps on human skin if it somehow forcefully hits the fasteners. The external threads of the screws inserted into these nuts are securely enclosed within the dome.
Jam NutCheck Nut
Diameter
From M5 - Upto M100
From 1/4" - Upto 4"
Its primary application lies in fastening the standard nut into place by being threaded onto a bolt and made to run tight against the parent nut. This will ensure that the bolts do not move out of place and will be securely held against vibrations and small and constant movements.
Flange Nut
Diameter
From M4 - Upto M16
They are used to spread the load evenly to avoid uneven fastening surface of the operations. They also ensure that the fasteners are in place without moving about loosely. These wide flange nuts can be used as a replacement to the nut and washer combination.
Hex Nuts
Diameter
From M3 - Upto M100
From 1/4" - Upto 3"
They are six sided general purpose nut with internal screw threads. Hex nuts are one of the most common hexagonal fastener with internal threads that screws on to the shank of a hex head cap screw or other bolts.
