Product Description
1440PCS Metric Screw Aassortment Kit, 304 Stainless Steel M2 M3 M4 Bolts
- 90-DEGREE FLUSH FLAT HEAD: Precision-engineered with a 90-degree countersunk flat head that sits completely parallel with the material surface upon installation. This zero-protrusion design eliminates any risks of snagging, friction, or interference, making it the premier choice for low-clearance moving structures.
- MARINE-GRADE 304 STAINLESS STEEL: Forged from high-quality 304 stainless steel with exceptional rust resistance and anti-oxidation stability. Unlike standard carbon steel or cheap zinc-plated fasteners, these silver metric screws survive harsh humid garages, outdoor hobby tracks, and marine environments without tarnishing.
- MASSIVE 5-IN-1 FULL MATED KIT: A comprehensive 1440-piece comprehensive collection delivering a true all-in-one hardware loop. Each dimension slot provides perfectly matched flat head Allen bolts, hex nuts, flat backing washers, and split-lock spring washers, alongside 3 tailored L-wrenches for immediate setup.
- M2 M3 M4 EXHAUSTIVE SELECTION: Covers a high-accuracy specification grid from microscopic drone components (M2*4mm) to heavy-duty frame joints (M4*30mm). Extensively utilized by professional makers and DIY hobbyists for RC car chassis plates, 3D printer heatbeds, custom PC builds, and electronics.
- ANTI-MIGRATION CONTAINER EXPERT: Neatly arranged inside an impact-resistant, grid-divided transparent organizer case with secure snap-locks. The custom-molded interior partition grooves flush perfectly against the lid, ensuring microscopic washers and nuts never mix during transit. Inner size index included.
