Wedge Anchors (Carbon Steel, Zinc Plated)
Wedge anchors — also called through bolts or stud anchors — expand at the bottom of the hole when the nut is tightened, clamping the fixture and the base material together. They are the workhorse of structural fixing: one hole, one anchor, immediate load capacity, with no need to wait for curing. Suited to cracked and non-cracked concrete above C20/25.

Frequently Asked Questions
How does a wedge anchor work?
Drill the hole, clean it, insert the anchor through the fixture and tighten the nut. The cone at the anchor end wedges the expansion clip against the hole wall, clamping fixture and concrete together with immediate load capacity.
