Post-Installed Mechanical Anchor Bolt (Hollow/Under-Cut) Stainless Steel for Curtain Wall

Post-Installed Mechanical Anchor Bolt (Hollow/Under-Cut) Stainless Steel for Curtain Wall

The stainless steel mechanical anchor bolt is a post-installed fixing used to anchor curtain wall hardware, brackets and railings into concrete or steel structures. Its hollow / under-cut design expands against the drilled hole after installation, providing reliable holding strength without the curing time required by chemical anchors.

Supplied complete with nuts and washers, the anchor allows brackets and base plates to be fitted after the structure is in place, which makes it the standard choice for retrofit curtain wall connections and for on-site adjustments where drilled fixings are needed.

Installation & Usage

A hole is drilled into the concrete substrate to the required depth, cleaned of dust, and the anchor is inserted and expanded per the under-cut installation method. The bracket or base plate is then placed over the stud, and nuts and washers are fitted and tightened to the design values given in the project documentation. Avoid installing anchors too close to slab edges or concrete corners without checking the structural details first.

Quality Assurance

Every anchor bolt is 100% inspected before shipment for thread integrity, material hardness and surface finish. Material test certificates are available on request to support project specifications.
