The sleeve anchor bolt is a type of expansion bolt, consisting of a countersunk head bolt, an expansion tube, a flat washer, a spring washer, and a hexagonal nut. It is named so because the expansion tube part has a shape or structure similar to that of a shark fin, which can provide better expansion and fixation effects during installation.
Characteristics
Good anchoring performance: Through the unique shark fin shaped structural design, the shark fin part of the expansion tube can be better stretched and tightly adhered to the installation substrate when tightening the bolt, generating a large frictional grip force, thereby providing reliable anchoring effect. It can withstand large tensile and shear forces and can be used to firmly fix various equipment, components, etc. on substrates such as walls, floors, or ceilings.
Superior anti slip performance: Some shark fin expansion bolts are designed with anti slip function, which can effectively prevent bolt loosening caused by vibration, impact or other external forces during use, improving the stability and safety of fixation.
Easy installation: The installation process is relatively simple, just drill a hole of appropriate size on the substrate, insert the shark fin expansion bolt into the hole, and then tighten the nut to complete the installation. No complex tools and techniques are required, which can greatly improve construction efficiency.
Wide applicability: It can be widely used in fields such as building decoration, mechanical installation, pipeline fixation, bridge construction, and power facility installation. It is suitable for substrates made of various materials, such as concrete, brick walls, stone, etc.
