Jake Sales 5/16 in x 7 in Construction Lag Screw - Heavy Duty

In this review the Jake Sales 5/16 in x 7 in construction lag screw is evaluated for builders and DIYers who need a heavy duty fastener that grips treated lumber and resists corrosion. The single biggest reason to buy is the combination of a Type 17 notched, extra sharp point and a triple coating that together make starts quicker, reduce the need for pre-drilling, and deliver long term corrosion resistance in ACQ treated wood. For anyone building decks, pergolas, or structural connections this box of 300 screws aims to replace common lag bolts with a more reliable, construction-grade option.

Key Features

• Type 17 Notched Point: The extra sharp, notched point starts quickly and reduces walking so you can often avoid pre-drilling in common framing lumber.
• Triple Coated Finish: The heavy coating system gives strong protection against corrosion, suited for ACQ treated lumber and outdoor use.
• Heat Treated Steel: Manufactured from high quality heat treated steel to provide superior shear and compression strength compared with standard lag bolts.
• 1200 Hour Salt Spray Performance: The screws passed an extended salt spray test without coating failures, indicating reliable long term resistance in corrosive environments.
• Modified Truss Washer Head: The larger head diameter helps pull lumber tight and increases bearing area under the head for secure connections.

Who It's For

These lag screws are aimed at professional contractors, deck builders, and serious DIYers who need a structural fastener that performs in treated lumber and outdoor projects. The 7 in length and robust construction make them a solid choice for connecting beams, posts and heavy timbers where strength and corrosion resistance matter.

Those who should look elsewhere include users needing very small length screws or specialized stainless steel fasteners for marine immersion applications; this product is triple coated and corrosion resistant, but it is not presented as a stainless alloy for continuous saltwater submersion.

Pros & Cons

Pros

• High quality heat treated steel provides noticeably greater shear and compression strength than common lag bolts.
• Type 17 notched point reduces walking and often eliminates the need for pilot holes, speeding installation.
• Passed 1200 hour salt spray testing with no coating failures, giving confidence for outdoor builds with ACQ lumber.
• Large head and modified truss washer design pull lumber tight and improve bearing under load.

Cons

• These are coated, not stainless, so users demanding stainless alloy for constant immersion should consider alternatives.

Frequently Asked Questions

Are these compatible with ACQ treated lumber?
Yes, the triple coated finish is specified as ACQ treated lumber compatible to resist corrosion when used with common treated wood.

Do these screws require pre-drilling?
The Type 17 notched extra sharp point reduces the need for pre-drilling in many framing applications, though very dense hardwoods may still benefit from pilot holes.

What drive type do they use?
They use a Torx/Star drive for secure bit engagement and reduced cam-out during installation.
