Product type
Machine screws are fasteners designed to be inserted into pre-tapped holes or used with nuts. They are typically made from materials such as carbon steel, stainless steel, or brass, providing strength and corrosion resistance. The design of machine screws allows for secure fastening in a variety of applications, making them essential components in machinery and equipment assembly.
| Material | Carbon steel, stainless steel, or brass |
| Head types | Flat, round, hex, or socket |
| Thread type | Unified National Coarse (UNC) or Unified National Fine (UNF) |
| Diameter range | M2 to M30 |
| Length range | 6 mm to 300 mm |
| Finish options | Zinc-plated, black oxide, or plain |
When selecting machine screws, consider the material based on the environment they will be used in, such as corrosion resistance for outdoor applications. Specify the required diameter and length to ensure compatibility with your components. Additionally, consider the head type for ease of installation and the thread type for proper engagement. Certifications may be relevant for certain industries, so check for compliance with any applicable standards.

UNC threads are coarser and provide better grip, while UNF threads are finer and offer better tension.
Machine screws are primarily designed for metal applications but can be used in wood with appropriate pre-drilling.
Machine screws typically range from 6 mm to 300 mm in length.
Yes, common finishes include zinc-plated, black oxide, and plain.
A screwdriver or wrench is typically required, depending on the head type.
Measure the hole diameter and depth, and refer to size charts for matching screw dimensions.
