Diverse surface treatments, enhancing product durability
Tianlong Round Head Square Neck Bolts come with options such as plain, black plated, zinc plated, yellow plated, and Hot-Dip Galvanized (H.D.G) finishes. Among them, zinc plating and H.D.G can improve corrosion resistance; black/yellow platings are more aesthetically pleasing.
Various high-strength grades available
Tianlong Round Head Square Neck Bolts are available in strength grades of 4.8, 8.8, 10.9, and 12.9. The 12.9-grade high-strength bolts can even meet the fastening requirements of heavy-duty equipment.
Round head and square neck structure
The square neck of this structure can be embedded into the groove of the connecting part, preventing the bolt from rotating and reducing the risk of loosening.
