Hex Washer Head Concrete Screw

Hex Washer Head Concrete Screws
Hex washer head concrete screws, also known as masonry self‑tapping anchors, are specially engineered fasteners for direct fastening into concrete, solid brick and block masonry.
Featuring an integrated hex flange washer under the head, they provide a larger bearing surface to distribute clamping pressure and prevent surface damage. The unique hi‑lo self‑cutting thread taps its own thread inside a pre‑drilled hole, no plastic wall plug is required.

They are driven by socket wrench or impact driver. Ideal for mounting brackets, steel profiles, guardrails, cable trays and equipment bases onto concrete substrates.

✅ Integrated Hex‑Washer Flange Head

One‑piece hex flange design removes the need for separate washers. Larger bearing surface spreads clamping pressure, avoids workpiece damage and supports higher installation torque.

✅ Hi‑Lo Self‑Cutting Masonry Thread

Special dual‑height thread taps its own thread in pre‑drilled holes. No plastic expansion plugs required, faster and neater installation.

✅ Wide Material Compatibility

Works reliably on concrete, solid brick, concrete block and other masonry substrates. Not suitable for pure hollow cavity, drywall or wooden base.

✅ Two Surface Finishes Available

Made of hardened carbon steel, offered in Zinc‑Plated (clear zinc) and Yellow‑Zinc Plated finishes for basic indoor & sheltered outdoor anti‑rust requirements.

✅ Heavy‑Duty Fastening Solution

Perfect for mounting brackets, guardrails, cable trays, pipe supports, steel frames and equipment bases onto concrete walls or floors. Fits socket wrench and impact driver installation.
