• Corrosion‑Resistant 304 Stainless‑Steel Construction:All machine screws and hex nuts are made of solid 304 stainless‑steel. It provides outstanding anti‑oxidation and chemical‑corrosion resistance and is mildly magnetic. Burr‑free consistent full coarse‑thread supports repeated disassembly, far more durable than carbon‑steel fasteners in damp‑indoor environments
• 56‑TPI UNC Coarse Full‑Thread Specification:Adopts standard #2‑56 UNC 56‑threads‑per‑inch coarse full thread. Thread precision is stable, perfectly interlocked with the matching #2‑56 hex nuts, effectively resisting loosening caused by slight vibration for instruments, circuit boards and small‑machinery installation
• 82° Standard Countersunk Flat‑Head Structure:The 82‑degree chamfer under the head conforms to standard imperial fastener specifications, allowing the screw to sink fully flush into countersunk holes without protruding. Standard Phillips cross‑head fits regular cross screwdrivers, avoiding tool‑slippage during tightening
• ANSI‑ASME B18.6.3 Industry Standard UNC Coarse Thread:Designed to meet ANSI B18.6.3F standards. Standard UNC coarse thread provides stable locking‑force, resists loosening under minor vibration, perfectly fits tapped holes and matching imperial‑hex nuts for equipment assembly and maintenance
• Compact See‑Through Compartmentalised Plastic Storage Organizer:Comes with a lightweight transparent divided‑plastic case. Screws and nuts are stored in individual separated compartments for quick size identification. Compact size is convenient to carry for electronics‑repair workshops, laboratory work and home DIY‑assembly projects
