the bearing surface and are equal in depth to the cylindrical length. The cylindrical portion diameter is slightly smaller  than the hex width.


The slots are for the insertion of a cotter pin to secure the nut when used with a drilled shank fastener. Commonly  used in the automotive industry to secure front wheel bearings or wheel hubs to spindles on cars and trucks. Castle  nuts are interchangeable with hex slotted nuts.

A set screw is generally used to secure one object within another. The set screw passes through a threaded hole in  the outer object and is tightened against the inner object to prevent it from moving relative to the outer object.  Exerting its clamping force through the bottom tip of the screw that projects through the hole rather than with a larger  head that remains outside. This type of screw is used to prevent relative motion between two rotating parts, such as  the movement of pulley on a shaft.

This type of screws comes in various types, which is as follows: 


Cup Point Set Screws: 
A cup point screw is the most comonly used set screw featuring a cup-shaped indentation on one end. Thie cup  point of this screw is mainly used for a quick, semi-permanent or permanent part assembly where the cutting in of  the cup point edge of the screw is acceptable.


Cone Point Set Screw:
The cone point screw has a sharp pointed tip on one end. It is used for the permanent setting of parts. These set  screws offer the highest holding capability, due to the deep penetration of the cone point.


Flat Point Set Screw:
A flat point screw has a flat surface on one end and is indeed the simplest and least expensive type of set screw  available. This type of screw is used for frequent relocation of parts where minimal shaft deformation is required.


Half Dog Point Set Screw:
The half dog point screw has a flat tip protruding from one end which is normally located into a groove in a shaft and  allows the shaft to rotate whilst retaining the part in place. This type of screw is typically used for a permanent setting of parts and often is used in place of a Dowel Pins.


Oval Point Set Screws:
An oval point set screw features an oval shaped point on one end. This set screw is used in an environment where  frequent adjustments are needed and minimal deforming of the part is required.


Slotted Set Screws:
Slotted Set Screws have a fully threaded body that extends over the slot right to the end of each part. The Slot is  used for driving the part into whatever application it is needed in. Some advantages to using slots are ease of use  since everyone has flat head screw drivers. Another nice feature is that if they are used in an outdoor environment  they are easy to clean out if debris gets caught in them.


Hex or Allen Socket Set Screw:
Hex Socket Set Screws are the most common type of set screws with a 6 sided hex in one end with threads  extending over the whole length of the screw. The Hex Socket offers the user the ability to have easy adjustment  without slippage. They also allow for high torqing on the screws so as to hold objects tighter in place. Can also be made in the other materials as per cutomer's requirements.

Slotted Round Nuts are parts generally made of Stainless Steel, which are designed to be used for various  purposes as for instance in electrical engineering. They can be tightenend by means of a slotted screw drivers & are  intended to be used for locking components where no specific prestressing forces or a specific resistance to  stripping are required.

Sizes: According to customer’s requirements.
Material: Stainless Steel & Mild Steel.
Can also be made in the other materials as per cutomer's requirements.

Item Code: Din-431


Pipe Nuts are solder less tube fitting hexagonal nuts. They come in two types i.e. Form A and Form B.
Sizes: According to customer’s requirements.
Material: Stainless Steel & Mild Steel.
Can also be made in the other materials as per cutomer's requirements.
