Expansion Bolts

Expansion Bolts (Parabolts): Maximum Strength Mechanical Rock Anchors

Expansion bolts, widely known as parabolts, are indispensable mechanical anchors in rock climbing and caving, engineered to permanently fix hanger plates, ropes, carabiners, and safety systems into the rock. These hardware components constitute a vital part of the protection chain in sport climbing routes, bolting projects, and underground caves. Their primary function is to provide an unyielding structural anchor point capable of withstand heavy fall forces.

Manufactured under the most rigorous European safety standards, our expansion bolts guarantee a uniform internal sleeve expansion inside the drilled hole. This ensures optimal load distribution even under the harshest outdoor conditions. Available in various diameters and lengths, they adapt precisely to different rock densities and types, from limestone and granite to conglomerate.

Explore our selection of premium bolting hardware and choose the right expansion bolts for your route-setting or re-bolting mountain projects. Gear up with certified components that deliver outstanding environmental durability and top-tier engineering reliability, allowing you and the entire climbing community to move upward with absolute peace of mind.
