The Ultimate Anchoring Solution for Solid Base Materials.
An Expansion Bolt is a mechanical fastener designed to create a secure, permanent hold in solid base materials like concrete, masonry, and natural stone. Through its unique expansion mechanism, it provides exceptional pull-out strength and reliability, making it essential for structural applications, heavy-duty fixtures, and safety-critical installations.
Radial Expansion Mechanism: Expands evenly against the base material when tightened, creating powerful friction and mechanical interlock.
High Load-Bearing Capacity: Engineered to support significant static and dynamic loads, including seismic and vibration forces.
Versatile Sleeve Design: Available with lead, steel, or nylon sleeves to suit different materials and environmental conditions.
Easy Visual Verification: Many designs allow installers to see when the bolt is properly set and fully expanded.
Corrosion-Resistant Materials: Commonly available in hot-dip galvanized steel, stainless steel (A2/A4), and zinc-plated options.
