Set Screw

DESCRIPTION:

A set screw is a type of fastener used to secure one object within or against another object, typically by exerting pressure through the screw into the object being fastened.

Set screws are threaded fasteners with no external head like a typical screw or bolt. Instead, they usually have a recessed or internal socket, such as a hex socket, for a wrench or screwdriver to tighten or loosen them.

The primary purpose of a set screw is to prevent relative motion or separation between the two objects it is securing. They are commonly used in various applications, including:

1. Securing components on a shaft: Set screws are often used to lock gears, pulleys, knobs, or other components onto a shaft, preventing them from slipping or moving.
2. Fastening parts in machinery: Set screws are used in machines and equipment to hold parts in place, ensuring proper alignment and functionality.
3. Locking adjustment mechanisms: In some devices, set screws are used to lock adjustable parts in a fixed position, maintaining a specific setting or alignment.
4. Electrical and electronic applications: Set screws can be used to secure wires, connectors, and components in electrical and electronic assemblies.

Set screws come in various sizes, materials (such as steel, stainless steel, or brass), and styles (including cup point, flat point, cone point, and others) to suit different applications.

The choice of set screw type and size depends on the specific requirements of the fastening task. Proper installation and torque application are essential to ensure the set screw functions effectively without damaging the objects it’s securing.

CLASSIFICATION & DIMENSIONS:

1. Flat Point Set Screw – DIN 913:

A flat point set screw has a flat, blunt end. It provides more surface contact with the object it’s fastening, making it suitable for applications where the screw needs to bear a load without damaging the mating surface. Flat point set screws are often used on hardened shafts.

2. Cone Point Set Screw – DIN 914:

Cone point set screws have a pointed end in the shape of a cone. They provide a sharp, penetrating point and are designed for use on soft materials like plastic or wood, where a deep penetration is necessary for a secure grip.

3. Dog Point Set Screw – DIN 915:

Dog point set screws have a flat, rectangular tip with a shallow indentation. They offer a compromise between the holding power of a cup point and the flatness of a flat point. They are often used on shafts that rotate and require a non-marring set screw.

4. Cup Point Set Screw – DIN 916

This type of set screw has a rounded, cup-shaped indentation on the end. It provides a firm grip and is often used when minimal protrusion or damage to the mating surface is desired. Cup point set screws are suitable for use on relatively soft materials.

5. Oval Point Set Screw

Oval point set screws have a slightly rounded, oval-shaped point. They are designed to provide good contact without excessive penetration. This type is suitable for use on hardened or fragile surfaces.
