Bobibbi metal roofing screws are #10 x 1-1/2 inch hex head fasteners designed specifically for securing corrugated metal roofs, as well as wood, slate, and sheet metal applications. They suit homeowners, contractors, and DIY enthusiasts tackling roof repairs, patio covers, sheds, or outbuildings where reliable, weatherproof fastening is essential.
Standout features include hilo threading for easy penetration and superior grip, a Type 17 tail for quicker drilling without pre-drilling in most cases, and EPDM washers that compress for airtight seals. Real-world performance shines in user feedback, with many praising their ability to bite into sheet metal cleanly and hold firm on roofs, often outperforming expectations in speed and strength during installations like ridge caps or PBR panels.
Build quality relies on 1022A carbon steel hardened via high-temperature quenching, finished with galvanized Ruspert coating for exceptional corrosion resistance tested beyond 1500 hours in hydrochloric acid. The hexagonal heads meet U.S. standards, and the included free 1/4 hex driver bit adds convenience, though some note minor paint flecks or tight driver fit.
Potential drawbacks include occasional paint chipping in the container and slower self-drilling through multiple layers, where pre-drilling is recommended for stability. Heads may require extra effort to seat in drivers compared to some competitors.
Overall, these screws deliver professional-grade performance at an accessible level, backed by a lifetime warranty. They earn high marks for value and reliability, making them a top choice for durable metal roofing projects.
