Strong Mechanical Locking
Unlike ordinary expansion fasteners, JB/ZQ 4763 anchors generate expansion force through mechanical deformation inside the concrete hole, ensuring dependable fixation.

JB/ZQ 4763 Expansion Bolt is a mechanical anchoring fastener designed for secure fixing in concrete structures. Featuring a rear-cut expansion mechanism, the anchor creates a reliable expansion force inside the drilled hole, providing stable load-bearing performance for industrial equipment, construction projects, and heavy-duty installations.
Manufactured according to JB/ZQ 4763-2006, this expansion bolt is available in multiple metric sizes, including M8, M10, M12, M16, M20, and M24, with customized materials, coatings, and dimensions available for different engineering requirements.


Rear Cut Expansion Structure
The specially designed rear-cut expansion section creates strong mechanical interlock inside the drilled hole. This structure improves anchoring reliability and provides stable holding force under heavy loads.
High Load-Bearing Performance
JB/ZQ 4763 expansion bolts are engineered for applications requiring secure fixing strength, making them suitable for industrial equipment, steel structures, support systems, and concrete installations.
Wide Material & Surface Options
Available in carbon steel and stainless steel versions with different surface treatments, providing excellent adaptability for indoor, outdoor, and corrosion-sensitive environments.
Unlike ordinary expansion fasteners, JB/ZQ 4763 anchors generate expansion force through mechanical deformation inside the concrete hole, ensuring dependable fixation.
