Premium Flat Thread Rolling Dies for Screw and Bolt Making Machines
What is a Flat Thread Rolling Die?
A flat thread rolling die (also known as a screw plate or thread plate) is an essential precision tool used in bolt thread making machines and screw headers for cold-forming threads. Unlike cutting, thread rolling uses these high-grade alloy steel dies to displace material, creating a continuous, grain-flow-reinforced thread on a shank or blank.
Whether you are manufacturing standard fasteners or specialized components, choosing the right screw thread rolling die ensures a smooth surface finish and exceptional thread strength. Our dies are engineered for longevity, featuring optimized hardness to withstand high-speed production cycles in the automotive and construction industries.

Pro Tip: To ensure a perfect fit, please inform us of your machine brand and provide a technical drawing when requesting a quote for OEM thread rolling dies.
Advantages of the Flat Die Rolling Process
Using a flat thread rolling die is one of the most reliable cold-forming processes in the industry. The primary advantages include:
- High Efficiency: The thread is fully formed within a single working stroke.
- Material Savings: Cold forming eliminates scrap metal (chips) produced by traditional cutting.
- Enhanced Strength: Rolled threads are typically 10-20% stronger than cut threads due to grain flow preservation.
- Cost-Effective: Ideal for high-volume production in the fastener and automotive sectors.
