Dear customers and friends：
Introduction
Fasteners are the unsung heroes of engineering, playing a critical role in the structural integrity of everything from aerospace components to medical devices. Among the many types of fasteners, Chrome Button Head Screws stand out for their innovative design, superior performance, and adaptability to demanding environments. This article delves into the technical specifications, applications, and advantages of these high-performance screws, while also exploring the company behind their production: Shijiazhuang Dellee Ming Garments Co., Ltd.. Whether you're a manufacturer, engineer, or procurement specialist, this guide will provide a comprehensive understanding of why these screws are a preferred choice in critical industries.
Product Overview
The Chrome Button Head Screws are engineered to meet the rigorous demands of modern manufacturing. Their design incorporates advanced materials and precision engineering to ensure optimal performance in a wide range of applications. These screws are particularly renowned for their optimized load distribution, high-torque drive system, and performance-graded materials. Let’s explore each of these features in detail.
Key Features and Advantages
Optimized Load Distribution
The radially curved bearing surface of these screws is a standout feature, designed to minimize point loading on soft substrates such as composites and cast alloys. This innovation ensures even stress distribution, reducing the risk of material deformation or failure. For example, the head height tolerance is tightly controlled at ±0.20mm, which is significantly tighter than the DIN 912 standard (e.g., M6: 4.0mm vs. DIN 912’s 6.0mm). This precision makes them ideal for applications where weight savings and structural integrity are paramount, such as aerospace turbine assemblies.
High-Torque Drive System
The extended socket depth of these screws, which is at least 1.5 times the nominal diameter per DIN 7991:2014 Section 4.3, ensures a secure grip during installation. This design is complemented by ISO 10664 Class C drive conformity with a tolerance of ±0.028mm, guaranteeing compatibility with a wide range of tools. The high-torque drive system is particularly beneficial in automotive applications, where it prevents thread galling in aluminum engine blocks.
Performance-Graded Materials
These screws are manufactured using 12.9/10.9/8.8 strength classes of SCM435 alloy steel, ensuring exceptional durability and load-bearing capacity. Additionally, they feature corrosion protection through black oxide treatment (≥96 hours of salt spray resistance) and Geomet® coating (≥720 hours of corrosion resistance). The medical industry benefits greatly from these properties, as the passivated stainless steel meets ISO 13485 biocompatibility standards.

Applications in Critical Industries
Aerospace
The reduced head height of these screws contributes to weight savings in turbine assemblies, a critical factor in aerospace engineering. By minimizing material usage without compromising strength, these screws help manufacturers meet stringent weight and performance requirements.
Automotive
In automotive applications, the radially curved bearing surface prevents thread galling in aluminum engine blocks, a common issue in high-torque environments. This feature ensures long-term reliability and reduces maintenance costs.
Medical
The passivated stainless steel and corrosion-resistant coatings make these screws ideal for medical devices that require ISO 13485 biocompatibility. Their precision engineering ensures that they meet the exacting standards of the healthcare industry.
Precision Engineering
The head-to-shank transition radius of ≥0.1d reduces stress concentration, making these screws suitable for precision engineering applications. This design minimizes the risk of fatigue failure in components subjected to cyclic loading.
