#14 x 3 in Lag Screws (440 pcs) - Heavy Duty Black Washer Head

In this review of the #14 x 3 in lag screws pack the bottom line is simple: these are a heavy duty, value-minded option for outdoor wood projects where corrosion resistance and driving ease matter. The pack of approximately 440 screws and two T30 star bits is aimed at DIYers and professionals who need a large supply of sturdy fasteners with a washer head and a Torx drive. The reviewer found the thicker carbon steel rod, special heat treatment and epoxy coating deliver dependable mechanical strength and good rust protection for decking and structural wood uses.

Key Features

• Rugged construction: Thickened low carbon alloy steel with a special heat treatment gives the screws higher mechanical strength and greater resistance to deformation under load.
• Anti-corrosion coating: A four-layer epoxy coating that passed a 1000-hour salt spray test helps the screws resist rust in outdoor conditions and extend service life.
• Torx T30 star drive: The T30 star drive reduces cam-out and makes installation faster with less slippage compared with standard Phillips heads.
• Knurl thread design: Mid-shank knurling and a new generation wood thread reduce the chance of splitting hardboard and improve holding power in structural wood.
• Value pack: Approximately 440 pieces plus two T30 bits provide plenty of fasteners for large jobs without repeated trips to the store.

Who It's For

These screws are well suited to contractors, deck builders and serious DIYers who need a large quantity of durable lag screws for outdoor wood framing, deck ledger attachments and other structural timber connections. The washer head and knurling are useful when a broad bearing surface and reduced splitting risk are needed.

Homeowners with occasional light projects might find the 440-piece count excessive; those requiring stainless-steel corrosion resistance for extremely salty coastal exposure should consider marine-grade fasteners instead.

Pros & Cons

Pros

• Strong, heat-treated carbon steel construction that resists bending and offers solid mechanical properties.
• Durable four-layer epoxy coating with proven salt spray resistance for outdoor use.
• Torx T30 drive and included bits make driving faster and reduce bit slip.
• Large quantity and included bits provide good value for big projects.

Cons

• Coating paint resistance received mixed feedback from customers, so some pieces may show flaking under extreme handling.
• Not stainless steel, so for the most corrosive environments a different alloy may be preferred.
