Key Features of GB-T 77 Hexagon Socket Set Screws with Flat Point
Flat Point Design for Surface Protection
The GB-T 77 Hexagon Socket Set Screws with Flat Point are equipped with a flat tip that applies even pressure on the mating part without penetrating the surface. This design is ideal for applications where surface integrity must be preserved.Internal Hex Drive for Compact Fastening
The internal hexagon socket allows for easy installation using a standard Allen wrench. This feature enables a clean, flush appearance and is particularly useful in confined spaces or where external driving tools cannot be used.Strong Holding Power Without Material Deformation
The flat point design of the GB-T 77 Hexagon Socket Set Screws with Flat Point offers high clamping force while minimizing damage. It’s well-suited for adjustable parts or where the screw will be frequently removed and repositioned.Available in High-Strength Materials
These screws are commonly manufactured from carbon steel, alloy steel, or stainless steel. The GB-T 77 Hexagon Socket Set Screws with Flat Point are often surface-treated with black oxide, zinc plating, or passivation to enhance corrosion resistance.Precision Threads for Stability
The threads on the GB-T 77 Hexagon Socket Set Screws with Flat Point are produced to strict tolerances for maximum engagement, vibration resistance, and overall fastening reliability.
Applications of GB-T 77 Hexagon Socket Set Screws with Flat Point
Shafts and Collars
The GB-T 77 Hexagon Socket Set Screws with Flat Point are frequently used to secure pulleys, gears, and collars onto shafts. The flat point prevents scoring or deforming the shaft surface, making it ideal for rotating assemblies.Electronics and Precision Instruments
In electronics and optical devices, the GB-T 77 Hexagon Socket Set Screws with Flat Point provide secure, non-invasive fastening. They allow for component adjustment and reassembly without damaging sensitive surfaces.Automotive and Aerospace
For applications requiring small, high-performance fasteners, such as in control systems or sensor mounting, the GB-T 77 Hexagon Socket Set Screws with Flat Point offer compact strength and reusability.Robotics and Automation
In robotics, where repeated motion and vibration are common, these set screws ensure stable mechanical connections that can be adjusted or removed as needed—without wear or damage to internal components.Fixtures, Jigs, and Tooling
The GB-T 77 Hexagon Socket Set Screws with Flat Point are essential for securing removable parts in jigs, fixtures, and machine tooling, especially where non-marring pressure is required.
Advantages of GB-T 77 Hexagon Socket Set Screws with Flat Point
✅ No Surface Damage
The flat point ensures that the GB-T 77 Hexagon Socket Set Screws with Flat Point grip securely without leaving marks or indentations on the mating surface.✅ Flush Installation
The internal hex design allows the screws to sit flush or below the surface, improving safety, aesthetics, and function in moving parts.✅ Reusability
Thanks to the non-damaging tip, the GB-T 77 Hexagon Socket Set Screws with Flat Point can be used repeatedly on the same surface without compromising performance.✅ High Torque and Stability
The hex socket drive allows high torque application during installation, ensuring a tight fit that resists loosening from vibration or dynamic forces.✅ Compliance with GB-T 77 Standards
Manufactured according to GB-T 77, these screws offer assured quality, dimensional accuracy, and compatibility with standardized mechanical designs.
The GB-T 77 Hexagon Socket Set Screws with Flat Point are engineered for precise, clean, and damage-free fastening in demanding applications. Their flat-point design ensures effective locking while protecting mating components, making them ideal for high-precision equipment, rotating assemblies, and adjustable systems. With excellent reusability, corrosion resistance, and ease of installation, the GB-T 77 Hexagon Socket Set Screws with Flat Point deliver long-term performance and fastening reliability in industries ranging from automation and electronics to mechanical engineering and aerospace.
