About Anchor nut

What is an Anchor Nut?

An Anchor Nut (also known as Formwork Anchor Nut, Tie Rod Anchor Nut, or Wing Anchor Nut) is a heavy-duty cast iron or steel nut used with Tie Rods in formwork systems. It securely tightens and holds formwork panels (shuttering) in place during concrete pouring.

Surya Engineering, a trusted manufacturer based in Mumbai, India, produces high-quality Anchor Nuts that are strong, durable, and perfect for Indian construction demands.

Why Use Anchor Nut?

Wet concrete creates huge pressure on formwork. Anchor Nuts work with Tie Rods to provide strong grip and prevent panels from bulging or shifting. They ensure accurate wall thickness, better concrete finish, and safer construction while reducing rework and material wastage.
