Machine screws are threaded fasteners designed for securing components in machinery, electronics, appliances, and other precision applications. They feature uniform threads along the shank and various head styles (Phillips, slotted, hex, pan, etc.) for specific tooling needs. Manufactured from carbon steel (Grade 4.8/8.8), stainless steel (304/316), or brass/nylon (for non-magnetic/non-conductive use), these screws offer reliable strength and corrosion resistance.
- Material:
- Carbon Steel (zinc-plated, black oxide).
- Stainless Steel (304/316, passivated).
- Non-Metallic: Brass, Nylon (UL94 V-0 compliant for fire resistance).
- Size Range:
- Metric: M1.6–M12 (ISO 14580, ISO 7045).
- Imperial: #0–1/2" (UNC/UNF, ASME B18.6.3).
- Head Styles:
- Phillips, Slotted, Hex, Pan, Flat (countersunk), Round, Torx.
- Thread Type: Full thread, partial thread, or self-tapping (for sheet metal).
- Finish: Zinc plating (RoHS/REACH), passivated (stainless steel), PTFE coating (low friction).
- Standard Carbon Steel/Stainless Steel: 10,000 pieces (common sizes like M3–M6 in stock).
- Non-Metallic/Custom Heads: 5,000 pieces (e.g., brass or Torx-head screws).
Factory Advantages: ISO-certified production, precision threading (tolerance: ±0.02mm), support for micro screws (M1.6–M2.5) and special drive types (e.g., security Torx), with lead times of 7–15 days for standard orders.
- Electronics: Securing PCBs, enclosures, and connectors in computers, servers, and IoT devices.
- Appliances: Assembling motors, hinges, and panels in refrigerators, washing machines, etc.
- Aerospace/Medical: High-precision screws for avionics, surgical tools, and medical devices (316 stainless steel with biocompatible coatings).
- Automotive: Electrical components, interior trim, and small mechanical assemblies.
- Precision Engineering: Tight thread tolerances ensure compatibility with pre-tapped holes in metal/plastic.
- Corrosion Resistance:
- Stainless steel options for high-humidity or chemical environments.
- Nylon screws for non-conductive, anti-corrosive applications (e.g., marine electronics).
- Tool Compatibility: Wide range of drive types (Phillips, Torx) for automated assembly lines.
- Non-Standard Sizes: Micro screws (M1.6), 超长螺丝 (up to 200mm), or metric-imperial hybrid threads.
- Special Coatings: Anti-seize (PTFE), conductive (nickel-plated), or UV-resistant (for outdoor use).
- Head Markings: Laser-engraved part numbers or logos for traceability.
