Hillman Fasteners 376532 Flat Head Concrete Screw

Product Description

The HILLMAN FASTENERS 376532 is a flat head Power Pro Blue concrete screw designed for anchoring into concrete, block, and masonry substrates. This 1/4-inch diameter by 2-1/2-inch length fastener features a blue corrosion-resistant coating that extends service life in demanding installation environments. The flat head profile sits flush with the surface after installation, making it a practical choice where a low-profile finish is required. Electricians, plumbers, and general contractors routinely specify concrete screws like this for securing conduit straps, pipe hangers, brackets, and equipment to masonry surfaces without the need for traditional anchors or lead shields.

This concrete screw is suited for light- to medium-duty fastening applications in residential and commercial construction. Typical uses include attaching electrical boxes, pipe supports, framing hardware, and equipment bases directly to poured concrete or concrete masonry unit walls and floors. The 1/4 x 2-1/2 inch sizing accommodates standard embedment depth requirements for most common masonry anchoring tasks. Sold in box quantity, this fastener is a standard stock item for contractors and service technicians who routinely work on concrete and masonry structures.

Key Features

• Flat head design sits flush with the surface for a clean, low-profile installation
• Blue corrosion-resistant coating for extended durability in masonry environments
• 1/4-inch diameter x 2-1/2-inch length fits common masonry anchoring applications
• Designed for direct installation into concrete, block, and masonry without a separate anchor insert
• Sold in box quantity for jobsite and service van stocking

Compatibility

Designed as an OEM-style replacement and standard-fit concrete screw for use in residential and commercial masonry fastening applications requiring a 1/4-inch flat head anchor screw.

Installation Notes

Installation requires drilling a correctly sized pilot hole into the concrete or masonry substrate with a carbide-tipped masonry bit prior to driving the screw. A hammer drill is strongly recommended for pilot hole drilling in concrete. Power down or de-energize any nearby electrical systems before anchoring near conduit or electrical equipment. Follow applicable building codes, including IBC and local masonry fastening requirements, for minimum embedment depth and edge-distance specifications.
