Product Description

A Cup Head Square Neck Bolt is a type of fastener used in various industries for attaching two or more pieces of material together. It has several distinctive features:

1. **Head Shape**: The term "Cup Head" refers to the shape of the head on the bolt, which is wider than it is tall and resembles a cup. This design allows for better surface contact with the nut, reducing the risk of galling (a type of metal degradation caused by friction).

2. **Square Neck**: The "Square Neck" part of the name refers to the flat area on the underside of the bolt head. This square neck helps prevent the bolt from rotating when a nut is being tightened onto it.

3. **Thread Type**: Cup Head Square Neck Bolts can be found with different thread types, including metric and imperial sizes. The threads are usually cut into the shaft of the bolt, allowing them to engage with a matching nut to create a threaded joint.

4. **Material**: These bolts are typically made from materials such as steel, brass, or stainless steel, depending on the application's requirements for strength, corrosion resistance, or aesthetics.

5. **Application**: They are commonly used in machinery, equipment, furniture assembly, and construction where a secure, non-rotating connection between two surfaces is needed.

6. **Size**: The size of a Cup Head Square Neck Bolt is specified by its diameter and length, often measured in millimeters for metric bolts or in inches for imperial ones. Other details like thread pitch and class of fit may also be indicated.

7. **Fastening Method**: They are usually fastened using a wrench or an impact tool, but they can also be used with an Allen key if the head is designed to accept one.

Always ensure that the bolt you choose matches the thread size, material compatibility, and strength requirements of your application to guarantee safety and durability.
