Heavy-Duty Expansion Anchors

Wedge Anchor Fasteners

Hyrax wedge anchor fasteners are high-strength, torque-controlled expansion anchors for fixing heavy loads into solid concrete. As the nut is tightened, the expansion clip wedges tight against the hole wall to deliver dependable hold-down values for structural and machine-mounting work.

Torque-controlled expansion for reliable, high pull-out values
Single-piece body — fast install through the fixture
Available in mild steel and stainless steel (SS 304 / SS 316)
Zinc-plated, hot-dip galvanized or plain finishes

Ask Our Team

A wedge anchor is a heavy-duty expansion fastener used to fix structural and machine loads into solid concrete. Tightening the nut pulls the cone into the expansion clip, locking the anchor against the hole wall.

We manufacture wedge anchors from M6 to M24 in multiple embedment lengths, with custom lengths available for project requirements.

Yes. We supply wedge anchors in SS 304 for general corrosion resistance and SS 316 for marine and chemical environments, in addition to zinc-plated and hot-dip galvanized mild steel.

Yes — choose hot-dip galvanized or stainless steel finishes for outdoor and corrosive exposure. Zinc-plated anchors are best suited to dry indoor conditions.
