1-8 Hex Nut Zinc NC

Overview The 1-8 Hex Nut Zinc NC (3679) is designed for hardware fastening applications requiring coarse-thread, zinc-plated hex nuts in standard National Coarse (NC) thread configurations. Specification Detail MPN 3679 Brand Midwest Fastener Thread Type Coarse (National Coarse / NC) Thread Size 1-8 Grade 2 Finish Zinc Plate Package Quantity 10 pieces Package Weight 3.91 lb Technical Features Zinc-plated finish: Provides a corrosion-resistant surface coating, extending service life in general-purpose indoor and light outdoor environments. Coarse (NC) thread pattern: Enables faster engagement and installation, reducing assembly time compared to fine-thread variants, and offers greater resistance to cross-threading. 1-8 thread size: Large-diameter fastener specification suited to high-load structural and mechanical connections. Grade 2 designation: Meets standard commercial-grade strength requirements for general fastening applications where high-tensile alloy grades are not required. Standard hex geometry: Compatible with common wrench and socket tooling for straightforward installation and removal. Applications General construction and structural assembly requiring coarse-thread fasteners at 1-8 sizing. Mechanical and industrial equipment assembly where Grade 2 zinc-plated hardware meets specification. Repair and maintenance work involving replacement of standard hex nuts on bolted connections. Light to moderate load-bearing fastening in environments where basic corrosion resistance is required.
