Chrome Button Head Screws-Shijiazhuang Dellee Ming Garments Co., Ltd.|Optimized Load Distribution&High-Torque Drive System

Introduction

Chrome Button Head Screws represent a significant advancement in fastener technology, combining optimized load distribution, high-torque drive systems, and performance-graded materials to meet the demands of modern industries. These screws are engineered to address critical challenges in applications where structural integrity, durability, and precision are paramount. This article delves into the product features, technical specifications, key applications, and the company background of Shijiazhuang Dellee Ming Garments Co., Ltd., a leading supplier of high-quality fasteners.

Product Features and Technical Advantages

The Chrome Button Head Screws are designed with cutting-edge engineering principles to ensure optimal performance in demanding environments. Below are the core features that set these screws apart:

1. Optimized Load Distribution

The radially curved bearing surface of these screws minimizes point loading on soft substrates such as composites and cast alloys. This design reduces the risk of material deformation and ensures even stress distribution. For example, the head height tolerance of ±0.20mm (e.g., M6: 4.0mm vs. DIN 912’s 6.0mm) demonstrates a more compact profile, which is critical for weight-sensitive applications like aerospace components.

2. High-Torque Drive System

The extended socket depth (≥1.5× nominal diameter per DIN 7991:2014 Sec. 4.3) ensures robust torque transmission, reducing the likelihood of stripping during installation. The ISO 10664 Class C drive conformity (±0.028mm tolerance) guarantees precise fit and alignment, making these screws ideal for high-strength applications.

3. Performance-Graded Materials

Manufactured using SCM435 alloy steel, these screws are available in 12.9/10.9/8.8 strength classes, offering exceptional tensile and yield strength. Additionally, corrosion protection is achieved through black oxide coating (≥96h salt spray resistance) and Geomet® coating (≥720h salt spray resistance), ensuring longevity in harsh environments.

Key Applications

The Chrome Button Head Screws are engineered to excel in specialized industries where performance and reliability are non-negotiable. Here are some of the critical applications:

1. Aerospace

The reduced head height of these screws contributes to weight savings in turbine assemblies, a critical factor in aerospace engineering. Their radially curved bearing surface minimizes damage to composite materials, ensuring structural integrity without compromising performance.

2. Automotive

In aluminum engine blocks, the curved head design prevents thread galling, a common issue in high-torque applications. The high-torque drive system ensures secure fastening, even under extreme operating conditions.

3. Medical

For medical devices, these screws are manufactured with passivated stainless steel to meet ISO 13485 biocompatibility standards. Their corrosion-resistant coatings ensure long-term reliability in sterilization environments.

4. Precision Engineering

The head-to-shank transition radius (≥0.1d) reduces stress concentration, making these screws ideal for precision machinery and high-precision components. This design feature is particularly beneficial in applications requiring cyclic loading and fatigue resistance.
