Frequently Asked Questions (FAQs)
1. What are set screws used for?
Set screws, also known as setscrews, socket set screws, or grub screws, are threaded fasteners used to secure components in place. They are commonly used to affix two or more loose parts together, holding one component tightly against or inside a second surface. Set screws are versatile and can be used with wood, metal, and plastics.
2. What are the types of set screws?
There are four main types of set screws: knurl-grip cup, flat, oval, and cone. Knurl-grip cup screws have serrations on the cup edge for better grip. Flat screws have a tip that makes good contact on flat surfaces. Oval screws are used on U-shaped and V-shaped grooves or sloped surfaces. Cone screws have a sharp, cone-shaped point that provides strong holding power, especially on soft materials.
3. Can set screws be used on wood?
Yes, set screws can be used with wood, metal, and plastics. They are usually fully inserted into the receiving object and are commonly used to connect two objects together securely. Set screws are a versatile fastening option for various materials.
4. What is the strongest set screw?
The cone point set screw is known for its strong holding power. It has a sharp, cone-shaped point that wedges into the contact material, providing excellent torsional and axial holding strength. Cone point set screws are often used in permanent settings or as pivots or hangers.
5. Is a set screw weaker than a bolt?
Compared to bolts, set screws may be slightly weaker. Set screws are fully threaded from the shank to the head, while bolts have a portion of the shank that is not threaded. The threading process involved in creating set screws removes a small amount of metal, making bolts slightly stronger.
6. What can I use instead of a set screw?
If you need an alternative to a set screw, you can consider using grub screws. Grub screws serve the same purpose of securing components to shafts but are smaller and have less surface area. They are often used in applications where a prominent head would interfere with other components. Grub screws come in different shapes, including cup point, cone point, and flat point.
