Hillman Fasteners 376531 Flat Head Construction Screw

Product Description

The HILLMAN FASTENERS 376531 is a flat head Power Pro Blue construction screw designed for structural fastening applications in wood framing, decking, and general construction assemblies. The blue-coated finish provides corrosion resistance suited for treated lumber and outdoor exposure. At 1/4 inch in diameter and 1-3/4 inches in length, this screw is sized for medium-duty fastening tasks where a countersinking flat head profile is required. It is typically installed by carpenters, general contractors, and construction tradespeople using a standard power drill or impact driver.

This screw is well-suited for residential and light commercial framing, treated wood connections, and structural panel attachment. The flat head design allows the fastener to sit flush with or below the material surface, reducing snag points and providing a clean finish line. The Power Pro Blue coating is formulated to resist corrosion in contact with ACQ and other treated lumber chemicals, making it a practical choice for exterior framing and deck construction where code-compliant fastening is required.

Installation Notes

Installation is typically performed by carpenters or general contractors using a power drill or impact driver with the appropriate driver bit. Always power down or unplug tools before changing bits or clearing jams. When fastening into treated lumber, verify that the screw coating meets local building code requirements for corrosion resistance. Follow applicable building codes, including IBC framing fastener schedules, for structural applications.
