The reviewer found the Type 17 notched point and heat treated steel deliver real performance gains when fastening thick timbers and decking; the screws start without walking and the triple coating stood up to corrosive conditions in lab testing, making them a practical choice for outdoor structural work.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003e\n\u003cstrong\u003eType 17 Point:\u003c\/strong\u003e The notched, extra sharp point offers quick starts and reduces the need for pre-drilling in many framing situations.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eHeat Treated Steel:\u003c\/strong\u003e Manufactured from high quality heat treated steel for improved shear and compression strength compared with common lag bolts.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eTriple Coating:\u003c\/strong\u003e A triple coated finish provides corrosion resistance suitable for ACQ treated lumber and extended outdoor exposure.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003e1200 Hour Salt Spray Resistance:\u003c\/strong\u003e Passed an extensive salt spray test without coating failures, indicating durability in coastal or humid environments.\u003c\/li\u003e\n \u003cli\u003e\n\u003cstrong\u003eModified Truss Washer Head:\u003c\/strong\u003e The larger head diameter helps pull 4x and larger members tight and distributes load under the head.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis screw is aimed at professional carpenters, deck builders, and serious DIYers who regularly work with large dimensional lumber and need a fastener that excels in shear and compression.
