Overview

Zinc and Yellow Plated (ZYP) drop-in anchors are heavy-duty, deformation-controlled sockets designed for solid, non-cracked concrete. They provide a permanent, flush-fitting internal thread for suspending overhead services or bolting down removable machinery safely in dry, indoor environments.

How it works

Flush Permanent Socket: Remove and replace fixtures anytime without leaving protruding studs behind.

Foolproof Depth Setting: Expands securely independent of hole depth, preventing the anchor from sinking out of reach.

Class A1 Fire Rating: Meets strict commercial safety standards for heavy overhead structural suspensions.

The Smart Way to Suspend Indoor Loads

When bolting down heavy indoor machinery or temporary warehouse barriers, traditional stud anchors leave permanent metal rods protruding from the floor if you ever move the equipment.

These deformation-controlled anchors solve this by creating a permanent, heavy-duty threaded socket perfectly flush with your concrete surface. You get incredible flexibility to bolt and unbolt fixtures as needed, keeping your floors completely flat and safe.

Foolproof Depth Setting

One of the biggest headaches with drop-in anchors is pushing them too far down a deep hole, making it impossible for your bolt to reach the thread.

These anchors are specifically engineered to set accurately independent of hole depth. Once inserted and struck with a punch, they lock into place instantly, meaning they will not get lost inside deeply drilled concrete.

Reliable Indoor Durability

Built strictly for dry internal environments, the Zinc and Yellow Plated (ZYP) finish offers a clean, professional look.

It features a minimum 5µm protective coating. This provides excellent everyday resistance against standard indoor workshop wear, keeping your anchors solid and reliable.

Certified Fire Safety

When suspending overhead electrical and mechanical services, structural integrity during an emergency is absolutely critical.

These anchors carry a formally tested Reaction to Fire Class A1 rating. Whether you are an M&E engineer hanging heavy ductwork or a contractor securing internal scaffold rings, you can trust these fixings to perform safely when it matters most.

Frequently Asked Questions

Do I need a special tool to install these anchors?

Yes, you must use a dedicated setting punch (often called a drop-in tool). Hitting this punch with a hammer is what forces the internal wedge to expand. Simply tightening a bolt into the thread will not expand the anchor properly.

What happens if I drill the hole too deep?

That is the beauty of this specific anchor! It is engineered to set accurately independent of the hole depth, meaning it won't slide too far down and get lost in a deeply drilled hole when you strike it with the punch.

Can I use these outside to suspend a canopy?

No, the Zinc and Yellow Plated (ZYP) finish is designed strictly for dry, internal conditions. If you use them outside, they will eventually rust. You should use marine-grade stainless steel anchors for exterior work.
