Stainless Steel Zinc Grade 10.9 Hex Socket Button Head Screws with Collar
1.Products Details:
The pan head hexagon botton socket bolt with collar is a kind of high - performance fastener. It combines the characteristics of a flange pan - head, a hexagon socket, and a sealant.
The pan - head design provides a larger contact area and better clamping force, which can evenly distribute the force when fastening and enhance the connection stability. The hexagon socket allows for convenient operation with a hexagon wrench, ensuring accurate and reliable tightening.
The hexagon socket allows for convenient operation with a hexagon wrench, ensuring accurate and reliable tightening.
The sealant coated on the bolt plays a crucial role in preventing leakage. It can fill the gaps between the bolt and the mating parts, creating a reliable sealing effect to prevent the leakage of fluids or gases.
2.Key Features:
• Excellent Sealing Performance:
The sealant on the bolt can effectively fill the gaps between the bolt and the mating parts, preventing the leakage of fluids and gases, and ensuring the tightness of the connection.
• High Connection Strength:
The flange pan - head design increases the contact area and clamping force, evenly distributing the force during fastening, which improves the stability and strength of the connection and is suitable for high - load applications.
• Good Corrosion Resistance:
The sealant can isolate the bolt from the external environment, reducing the risk of corrosion and extending the service life of the bolt.
• Easy Installation and Removal:
The hexagon socket design enables the use of a hexagon wrench for convenient operation, allowing for accurate tightening and loosening, which improves work efficiency.
• Wide Applicability:
It is widely used in various fields such as mechanical equipment, automotive manufacturing, and pipeline connections, meeting the requirements of different working conditions for high - strength connections and sealing performance.
