Dear customers and friends：
Introduction
Chrome Button Head Screws represent a pinnacle of fastener technology, designed to meet the rigorous demands of industries such as aerospace, automotive, and medical engineering. Manufactured by Shijiazhuang Dellee Ming Garments Co., Ltd., these screws combine advanced materials, precise engineering, and corrosion resistance to deliver unmatched performance. This article explores their key features, technical applications, and specifications, supported by authoritative references and product imagery.
Key Features
Optimized Load Distribution
Radially curved bearing surfaces minimize point loading on soft substrates like composites and cast alloys. The head height tolerance of ±0.20mm (e.g., M6: 4.0mm vs. DIN 912's 6.0mm) ensures even stress distribution, reducing material deformation.
High-Torque Drive System
Extended socket depth (≥1.5× nominal diameter per DIN 7991:2014) and ISO 10664 Class C drive conformity (±0.028mm tolerance) ensure reliable torque transmission, even in high-stress environments.
Performance-Graded Materials
Available in 12.9/10.9/8.8 strength classes (SCM435 alloy steel), these screws meet stringent mechanical requirements. Corrosion protection includes black oxide (≥96h salt spray) and Geomet® coating (≥720h), as validated by NIST standards.
Key Applications
Aerospace
Reduced head height saves weight in turbine assemblies, critical for fuel efficiency and performance. NIST research highlights the importance of lightweight fasteners in aerospace engineering.
Automotive
Curved heads prevent thread galling in aluminum engine blocks, a common issue in high-temperature environments. This design aligns with NIST guidelines for material compatibility.
Medical
Passivated stainless steel meets ISO 13485 biocompatibility standards, ensuring safety for surgical and diagnostic equipment.
