This product is a high-quality hexagon socket countersunk head screw, produced in strict accordance with DIN7991 German standard and ISO10642 international industrial standards. The material of high-quality 304/316 stainless steel is optional, utilizing a hexagon socket drive and countersunk flat head design. After installation, the surface is flat and flush, making it suitable for all kinds of industrial and commercial equipment. The natural appearance of stainless steel is strong and durable, free from coating shedding or wear issues.
High-grade 304/316 stainless steel ensures strong corrosion resistance across indoor, outdoor, and humid environments.
Hexagon socket distributes force evenly to prevent slippage, providing reliable and long-lasting locking performance.
Countersunk head sits completely flush with workpiece surfaces, creating a neat, non-protruding, and professional finish.
Strict dimensional tolerance control guarantees seamless adaptability for accurate industrial and machinery assembly.
Tailored production available to meet diversified engineering requirements:
These screws are produced in strict accordance with DIN 7991 and ISO 10642 international industrial standards for dimensional and mechanical precision.
The countersunk design allows the fastener head to sit completely flush with the surface of the component, eliminating snag hazards and maintaining a smooth aesthetic profile.
304 stainless steel is ideal for standard indoor and outdoor applications, while 316 contains added molybdenum for superior corrosion protection in coastal, marine, or chemical environments.
Yes, custom services cover imperial threading, non-standard lengths, special thread pitches, and alternative materials such as alloy and carbon steel upon request.
No coating is necessary because stainless steel inherently resists rust. Surfaces retain their natural color without flaking, and optional chemical passivation is available for increased durability.
The hexagon socket drive allows for greater torque application, minimizes driver slippage (cam-out), and prevents damage to the fastener head during precision assembly.
