• All screws adopt full coarse thread; length is measured under the rounded pan head. Widely used for electronics, precision instruments, fixtures and general DIY imperial hardware replacement
• Corrosion‑Resistant 304 Stainless Steel Construction:All screws, nuts and flat washers are manufactured from solid 304 stainless steel. It provides superior anti‑oxidation and chemical corrosion resistance and may be mildly magnetic. Burr‑free uniform coarse threads support repeated assembly and disassembly, more durable than carbon steel fasteners
• Three Standard UNC Coarse Thread Specifications:Covers three most widely used small imperial coarse threads: #2‑56 (56TPI), #4‑40 (40TPI), #6‑32 (32TPI). Full‑length thread design ensures sufficient meshing depth with matched hex nuts, effectively resisting loosening caused by slight vibration of electronic and precision equipment.
• Practical Phillips Pan‑Head Structure:Curved smooth pan head will not scratch circuit boards, plastic casings and delicate metal surfaces. Standard Phillips cross recess fits regular cross screwdrivers tightly without slipping during tightening, ideal for narrow compact installation spaces of small devices
• Portable See‑Through Compartmentalized Plastic Storage Organizer:Equipped with split transparent plastic storage case. Each thread size and length fastener is placed in independent separated compartments for fast size identification. Compact lightweight box easy to carry for electronics repair shops, laboratory assembly and home DIY hardware projects
