Description
The Hex Socket Head Screw manufactured to DIN 912 / GB 70.1 standards is a precision-engineered fastener featuring a cylindrical head and an internal hexagonal drive. Produced from premium 316L stainless steel, this screw offers outstanding corrosion resistance, high mechanical strength, and long-term reliability in harsh and demanding environments.
Designed with a full-thread (full tooth) configuration, the screw ensures uniform load distribution along the entire shank, enhancing holding power and resistance to loosening under vibration. Its compact cylindrical head allows for installation in limited spaces while delivering a clean, professional finish. These attributes make the Hex Socket Head Screw an ideal choice for machinery, automotive systems, construction assemblies, marine equipment, and industrial applications where precision and durability are critical.
Features & Benefits
- Premium Corrosion Resistance: The use of 316L stainless steel makes this hex socket screw highly resistant to corrosion, particularly in harsh environments containing chlorides, acids, and other corrosive agents.
- High Strength and Precision: Adhering to the DIN 912 and GB 70.1 specifications guarantees a precise fit and superior tensile strength, making it ideal for high-stress applications.
- Full Threaded Design: The full teeth or full thread shank provides a stronger and more uniform grip along the entire length of the screw, ensuring maximum holding power and preventing loosening under vibration.
- Aesthetic and Functional: The cylindrical head offers a clean, flush finish when installed, while the internal hex drive allows for easy and secure tightening with an Allen wrench, especially in tight spaces.

FAQ:
Q1: Why should I choose a full-threaded screw over a partially threaded one?
A: A full tooth screw provides a more uniform grip throughout the entire length of the hole. This is ideal for applications where the screw is under constant tension or where maximum engagement with the material is necessary to prevent loosening.
Q2: Does this screw provide a flush finish?
A: Yes. Because it features a cylindrical head, the Hex Socket Head Screw can be installed into a counterbored hole, allowing the top of the head to sit flush with or below the surface of the material.
Q3: What is the advantage of using 316L stainless steel?
A: 316L stainless steel offers enhanced corrosion resistance due to its molybdenum content, making it ideal for marine, chemical, and high-humidity environments.
Q4: Are DIN 912 and GB 70.1 interchangeable?
A: Yes. DIN 912 and GB 70.1 have equivalent dimensions and performance requirements, making them interchangeable in most applications.
Q5: Can custom sizes or special tolerances be supplied?
A: Yes. Custom lengths, thread pitches, and tolerances can be provided upon request to meet specific project requirements.
