The kit includes twelve 1\/2 in x 5 in carriage bolts with a flat head, matching USS washers and hex nuts, and a five-layer ceramic black ruspert coating that promises roughly twice the rust protection of standard galvanized hardware. For anyone building decks, pergolas, gazebos or other exterior structures, the single biggest reason to buy is the combination of a semi-flush flat head and a durable black finish that holds up in ACQ treated lumber while keeping a clean visual line.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize consistency:\u003c\/strong\u003e The 1\/2 in diameter and 5 in length provide a reliable dimension for through-bolting typical deck and pergola timbers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSemi-flush finish:\u003c\/strong\u003e The flat head with a 1.062 in head diameter gives a neat, semi-flush appearance that blends into woodwork without large exposed heads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete kit:\u003c\/strong\u003e The pack of 12 bolts, 12 USS thick washers and 12 hex nuts supplies everything needed for multiple fastening points or a single medium-sized project.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced corrosion resistance:\u003c\/strong\u003e The 5-layer ceramic black ruspert coating is designed to deliver about 2X rust protection versus galvanized hardware for longer exterior life.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eACQ compatible:\u003c\/strong\u003e Rated suitable for use in ACQ treated lumber so it can be used with modern pressure-treated decking and structural members.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis kit is aimed at homeowners, carpenters and DIYers installing decking, pergolas, gazebos or other outdoor structures who want hardware that looks neat and resists corrosion better than standard galvanized bolts.
