Flat Head Square Neck Bolt" is a type of bolt that has a specific head shape and neck design. Here's a breakdown of the features:
- Flat Head: The head of the bolt is flat, meaning it has a broad, flattened top. This design can be useful in applications where a low-profile bolt head is desired or where clearance under the bolt head is limited.
- Square Neck: The neck of the bolt, which is the part that connects the head to the shank (threaded portion), has a square or rectangular cross-section. This square neck design provides increased bearing area and helps distribute the clamping force more evenly, especially when the bolt is used in shear-loaded applications.
Flat head square neck bolts are typically used in applications where a flush or nearly flush bolt head is required, such as in machine tool fixtures, dies, and other precision applications.
When selecting a flat head square neck bolt, it's important to consider factors like the bolt's material, diameter, length, and thread type to ensure it meets the requirements of your specific application.
