Material: Typically made from carbon steel or stainless steel (304 or 316 grade)
Coating: Zinc-plated, hot-dip galvanized, or plain finish
Thread Type: Full or partial threads
Head Style: Hex bolt, stud type with nut and washer
A hole is drilled into the concrete.
The anchor is inserted into the hole.
As the nut is tightened, the wedge clip expands against the concrete, locking the anchor in place.
Structural supports
Industrial machinery mounting
Racking and shelving
Railings and guardrails
Signage and lighting installations
HVAC and electrical systems anchoring
Strong and secure hold in concrete
Quick and easy installation
Suitable for static and dynamic loads
Available in corrosion-resistant options
