• 
  Size & thread: M5 diameter, 16 mm length; standard metric thread for easy pairing with nuts or tapped holes.
• 
  Head & drive: hexagonal head with a flat round bearing surface for a tidy, flush seating and solid torque transfer; compatible with common hex drivers or sockets.
• 
  Material: carbon steel—strong and versatile for indoor use and general-purpose assemblies.
• 
  Condition: used; may show light wear or install marks but functionally solid with smooth threads and secure clamping when properly installed.
• 
  Ideal uses: machinery enclosures, metal furniture frames, DIY projects, chassis assemblies, workshop repairs, and other non-structural or indoors applications where cosmetics aren’t critical.
• 
  Practical tips:
  • Inspect threads for burrs and clean before use to ensure easy installation.
  • Use the correct hex driver and avoid over-torquing to prevent thread damage.
  • Pair with matching nuts or tapped holes; for vibration-prone setups, consider a light thread locker or a locknut if appropriate.
  • Store in dry, clean conditions to slow any potential corrosion common to bare carbon steel.
• 
  Why choose USED? A cost-conscious option for non-critical applications where performance matters more than pristine appearance. If you need corrosion resistance or want brand-new hardware for critical loads, consider newer stainless or coated alternatives.
