Set Screw Assortment

SKU: CS12950PB Category:

Our Set Screw Assortment is comprised of high-grade alloy steel with hexagon-recessed heads and cup points for positive torque.

A socket set screw, alternatively called a grub screw, doesn’t have a head and is usually tightened or loosened with a hex or square key.

When a pulley or other machine component is attached to a shaft, a cup point set screw is used to keep it in place.

One kind of set screw known as a socket set screw cup point has a rounded tip that grips the shaft surface and prevents it from being deformed.

A hex socket set screw is a sort of fastener that is regularly utilized for the purpose of fastening various components in their intended positions.

This usually means combining multiple loose parts, such as by keeping one part firmly attached to a secondary component.

Grub screws and Allen set screws are distinguished from generic screws by their crucial pinning action of one component against another.

In a nutshell, they’re utilized to generate compression forces that are capable of securely holding two free items together without the usage of a nut as a third component.

In most cases, Allen head set screws will be utilized for the purpose of securing or “setting” pieces that, in the absence of the socket set screw, would be free to slide around one another.

To function properly, the hexagon socket set screw with cup point must first pass into a threaded entrance in one part before pressing firmly alongside a secondary part on the back side of the assembly.

They are able to carry out this setting utility as a result of the distinctive flat-ended tops that they have, which is a crucial component of the design of most set screws.

A broad variety of applications, including those in product designing, engineering, and maintenance, make extensive use of socket set screws found in our Set Screw Assortment Kit.

These screws are often employed to secure a component that may possibly move.

For instance, in different mechanical configurations and panel arrays, this might include anchoring a component against a baseplate.

The attachment of spindle handles and cams, as well as the fastening of pulley and gears to shafts, are both typical and specialized instances of the employment of a metric socket set screw.

A cup point set screw happens to be one of the most frequent kinds of set screw that are used in a variety of applications.

Cup point socket set screws are distinguished by the presence of a concave depression on the flattened tip end of the screws.

Instead of the flat tip making even contact with the back part, all of the pressure’s put on the narrower part of the cup point.

This configuration assists in producing a strong torque and keeping force on the item that is pinned, while at the same time avoiding the danger of damaging the end of the screw shaft as a result of overtightening.
