T-25 Flat Head Concrete Screws are built for strength, simplicity, and a secure hold in concrete, brick, or block. Whether you're mounting framing, attaching electrical boxes, or setting plates, these screws are engineered to cut through the job cleanly.
Their flat head sits flush with the material surface, making them ideal for applications where appearance or clearance matters. With a hardened steel build and a T-25 star drive, they offer high torque without cam-out, helping reduce stripped heads and installation headaches.
Available in a variety of lengths and diameters, they give you flexibility to match the thickness of the material and the strength of the hold you need. Use them for both temporary setups and permanent fixtures in residential, commercial, and industrial settings.
Key Features:
Flat Head Design: Sits flush for a clean, finished look.
T-25 Star Drive: Delivers high torque with minimal slippage.
High-Performance Threads: Designed for aggressive, consistent bite into concrete and masonry.
Durable Construction: Built for high-load applications with hardened steel.
Available Options: Multiple sizes to match your anchoring depth and material thickness.
Applications:
Framing & plate attachment
Mounting brackets, shelves, and ledger boards
Securing conduit straps and electrical boxes
Wood-to-concrete or metal-to-concrete connections
General construction and remodeling projects
Installation:
Drill a pilot hole using a carbide-tipped masonry bit
Clean out dust and debris from the hole for maximum grip.
Use an impact driver or drill with a T-25 bit to drive the screw flush.
Avoid over-tightening to preserve thread integrity and base material.
