Hillman Fasteners 376536 Flat Head Construction Screw 1/4x4

Product Description

The HILLMAN FASTENERS 376536 is a flat head Power Pro Blue construction screw sized at 1/4 inch diameter by 4 inches in length. This screw is engineered for heavy-duty structural fastening applications where a flush, countersunk finish is required. The blue coating provides corrosion resistance suited to treated lumber and exterior construction environments. It is typically installed by carpenters, general contractors, and construction tradespeople working on decking, framing, or structural assemblies.

This screw is well-suited for residential and commercial construction projects where a large-diameter, long-length fastener is needed to join dimensional lumber, engineered wood products, or structural panels. The flat head profile allows the fastener to sit flush with or below the surface of the material, making it appropriate for applications where a clean finished surface or additional layering is required.

Compatibility

Designed as an OEM-style replacement and standard construction fastener for use in heavy-duty wood framing, decking, and structural assembly applications requiring a 1/4 inch by 4 inch flat head screw.

Installation Notes

Installation is typically performed by carpenters or general construction tradespeople using a hex-head driver bit appropriate for the drive type. Pre-drilling a pilot hole is recommended when fastening near the edge of lumber to prevent splitting. Always follow applicable building codes, including those referenced in the International Building Code, when using structural fasteners in load-bearing assemblies. Ensure the correct driver size is used to avoid cam-out and damage to the fastener head.
