Key features and benefits:

• 
  Precise dimensions: M4 external thread with a 12 mm length ensures consistent fit in enclosures, brackets, and small assemblies where space is limited.
• 
  Hex socket drive: The hex/Allen socket lets you snugly tighten with a standard Allen key, reducing the chance of slippage during installation.
• 
  Flat round head: The flat, rounded head sits flush against the surface for a neat finish and minimizes snagging on moving parts, while providing reliable load distribution.
• 
  Used condition, with value: This item is sold as used. It offers an economical option for non-critical projects, hobby builds, or maintenance tasks where a new fastener isn’t necessary.
• 
  Versatile applications: Ideal for electronics enclosures, DIY projects, small appliance assemblies, cabinet hardware, and light machinery where a low-profile, secure fastener is preferred.
• 
  Practical use tips: Inspect the threads before reuse; clean any debris; use a proper hex key size to avoid stripping; start by hand-tightening to align the threads, then snug securely without over-torquing.

Why this screw stands out: Unlike generic fasteners, this M4x12 hex socket flat round head combines precise dimensioning with a flush-mount design and a cost-conscious used option, making it a smart choice for budget-conscious projects or when you’re patching parts that don’t bear heavy loads.
