• 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
• Anti‑Slip Knurled DIN912 Socket Head Structure:Unique knurled textured surface on the cap head increases friction for quick manual pre‑tightening without tools; built‑in internal hex socket fits standard allen wrenches for stable torque fastening without slipping. Low‑profile round cap fits narrow limited clearance installation spaces
• Dual Matching Nuts for Different Locking Needs:Comes with two types of supporting nuts: ordinary hex nuts for general fixed assembly; nylon insert locknuts with built‑in plastic ring, which generate friction to effectively prevent loosening under long‑term vibration, ideal for equipment with frequent movement.
• Portable See‑Through Compartmentalized Plastic Storage Organizer:Equipped with lightweight split transparent plastic storage case. Knurled screws, hex nuts, locknuts and flat washers are stored in independent separated compartments for instant size identification. Compact lightweight box easy to carry for mold workshops, electronics repair stations and home precision assembly projects.
