Metric Hexagon Socket Button Head Cap Screws
TUZ Metric Hexagon Socket Button Head Cap Screws feature a rounded button-shaped head with a hex socket for secure and efficient installation. The design offers a larger load-bearing surface for even force distribution, reducing material stress and enhancing reliability. These screws are made from durable SCM435 alloy steel or 304 stainless steel and conform to both ISO 7380 (dimensional standards) and ISO 898-1 (mechanical properties), ensuring consistent performance in demanding applications.
Surface Treatment:
Each feature of these hexagon socket button head screws is carefully designed to ensure reliable fastening, ease of use, and durability across a range of demanding applications.
Key Features
Comprehensive Size Range
TUZ Metric Hexagon Socket Button Head Cap Screws are available in sizes from M2 to M16, with lengths up to 100 mm. This range allows for compatibility across diverse application needs, from compact electronics to heavy machinery.
Wide Load-Bearing Surface
The button head design offers a larger contact area, evenly distributing force to minimize material stress and reduce loosening under vibration or stress, ensuring long-term reliability.
Hex Socket and Custom Anti-Tamper Options
The hex socket design allows deeper tool engagement, enabling high torque application without stripping the fastener. This makes it ideal for installations in confined spaces where traditional tools may not be practical. For enhanced security, TUZ also offers customized anti-tamper options, such as star-shaped recesses (Torx) or Torx recesses with a central PIN, preventing unauthorized adjustments or tampering while maintaining ease of installation.
Material Durability and Corrosion Resistance
Made from SCM435 alloy steel or 304 stainless steel, these screws deliver excellent durability and resilience. Stainless steel variants are ideal for outdoor or high-humidity environments due to their superior corrosion resistance. Additional surface treatments, such as black oxide, zinc, or nickel plating, provide enhanced protection against wear and environmental factors.
ISO Compliance for Performance and Reliability
All TUZ Metric Hexagon Socket Button Head Cap Screws meet ISO 7380 standards for precise dimensions and ISO 898-1 for mechanical properties. With tensile strengths exceeding 19,600 N and hardness ratings of HRC 39–44, these Class 12.9 screws are optimized for demanding, heavy-duty applications.
