High‑Wear‑Resistant Thread Rolling Dies High Hardness Thread Die Plate For Thread Rolling Machine

# Detailed Introduction of High‑Wear‑Resistant Thread Rolling Dies

## Product Overview

High‑wear‑resistant thread rolling dies are core forming molds for thread rolling machines and high‑speed thread rolling machines. They are mainly used for external thread roll forming of fasteners such as bolts, screws and self‑tapping screws. By means of relative movement of paired dies to extrude metal wire rods, standard threads can be formed in one pass, replacing traditional cutting processing. Featuring high forming efficiency and stable thread precision, they are widely used in production workshops for hardware fasteners, auto parts and construction standard components.

## Core Materials & Processes

Made of premium alloy tool steel, the dies undergo multiple forging processes, precision grinding, vacuum quenching and tempering treatments to improve overall hardness and impact resistance of the mold, and reduce risks of wear, tooth chipping and tooth loss on the thread working surface. Thread profiles are precisely ground with regular tooth shapes and high‑surface finish. Balanced hardness and toughness effectively prevent brittle fracture failure.

## Main Features

- **Excellent wear resistance & long service life**: The working surface delivers strong anti‑abrasion performance. Under identical working conditions, service life is greatly extended compared with ordinary thread rolling dies. It reduces frequent mold‑change downtime and lowers mold consumption costs.
- **High thread forming accuracy**: Pitch and tooth profiles are manufactured strictly in accordance with GB, DIN and other standards. Rolled‑out screw threads are full‑formed, burr‑free and defect‑free, and pass go‑no‑go gauge inspection.
- **Compatible with multiple workpiece materials**: Suitable for processing common carbon steel, 10B21, 40Cr and other widely‑used fastener steels for thread rolling of cold‑forged semi‑finished screw blanks.
- **Strong compatibility**: Fits various high‑speed thread rolling machines. Standard‑size products are in stock, and non‑standard customization is available per customer‑specified pitch and screw dimensions.
- **Great stability**: Uniform heat treatment minimizes deformation during operation. It guarantees good consistency for mass production and is suitable for high‑volume continuous manufacturing.

## Applicable Equipment

High‑speed thread rolling machines, rebar thread rolling machines, fully‑automatic thread rolling machines and other thread‑rolling equipment.

## Applicable Products

Machine screws, self‑tapping screws, bolts, studs, non‑standard fasteners and other external‑thread workpieces.

## Optional Services

- Ready stock for standard specifications
- Custom non‑standard thread rolling dies: custom pitch, tooth profile and overall dimensions according to drawings or samples
- Multiple hardness grades available to match different working conditions for soft and hard materials

## Precautions for Use

1. Ensure flat fitting of dies during installation and properly adjust clearances to avoid tooth chipping caused by uneven stress.
2. Special thread‑rolling oil is recommended during production for cooling and lubrication to further prolong die service life.
3. When processing high‑hardness materials, select higher‑grade wear‑resistant dies to prevent rapid wear.
