Why this screw matters

• 
  High-tensile strength: grade 10.9 construction delivers superior load-bearing capability for strong, secure joints in small assemblies.
• 
  Galvanized finish: corrosion-resistant coating protects threads and inner components in workshop or humid environments.
• 
  Compact, flush design: cylindrical head minimizes protrusion, reducing snag risk in confined spaces and enabling cleaner assemblies.
• 
  Precise sizing: M4 thread with a 12 mm length fits thin panels and compact mechanisms without unnecessary length.
• 
  Hex socket drive: recessed Allen drive provides a snug fit with reduced cam-out, ideal for tight work-in-progress or awkward angles.
• 
  Used, inspected condition: carefully checked to ensure functional integrity while offering a practical option for non-critical applications.
• 
  Includes after-sale accessories package: adds convenience for immediate use and streamlined integration into your build.

Ideal use cases

• Small electronics enclosures, RC models, and compact machinery where space is at a premium.
• DIY furniture connectors, brackets, and modular assemblies requiring a reliable M4 fastener with a low-profile head.

Durability, finish, and compatibility

The galvanized coating protects against moisture and ordinary wear, while the cylindrical head design helps distribute clamping force evenly. Pair this M4x12 bolt with compatible nuts and washers for robust joints in aluminum, plastic, or steel components. For best results, lubricate threads during installation and inspect for any thread damage or wear before reuse.
