*USED* Hexagon socket cylindrical head carbon steel galvanized screw_M4*16_10.9 level_Drop resistance_After-sale accessories package_Mechanical semi-finished products_mini

Discover a compact, high-strength fastener that fits right into tight spaces: the used M4x16 hex socket cylindrical head screw. Crafted from carbon steel and zinc galvanized for durability, this component blends reliable strength with practical, real-world toughness. The 10.9-level tensile capability ensures it holds assemblies securely under load, even in small mechanical builds or prototypes.

Why this screw stands out

• 
  Compact, high-tensile design. M4 diameter with a 16 mm length delivers strong grip without bulk, ideal for crowded enclosures, electronics housings, and mini projects.
• 
  Cylindrical head with hex socket. The flush, low-profile head pairs with a hex key for precise driving and clean finish in assembled parts.
• 
  Carbon steel, galvanized finish. Galvanization provides corrosion resistance in everyday environments, extending service life in workshop or light outdoor use.
• 
  10.9 level strength. This high-tensile level supports dependable performance in assemblies that demand stiffness and reliability from a small fastener.
• 
  Used, with after-sale accessories package. Ready for immediate integration into your workflow, with additional post-purchase support items included to facilitate installation and ongoing maintenance.
• 
  Mechanical semi-finished, mini format. Perfect for hobbyists, educational kits, small-scale manufacturing, and DIY enthusiasts who value precision in miniature builds.

Ideal use cases

• Enclosures and electronics housings where space is at a premium but a secure joint is required.
• Miniature machinery assemblies, robotics projects, and prototype fixtures that benefit from a tidy, flush drive.
• Furniture or cabinetry connectors that need a concealed fastener with dependable withdrawal resistance.
• Repair or retrofitting tasks where a cost-effective, high-strength screw is preferable to premium alloys.

Practical tips for installation and care

• Use a properly sized hex key (typically around 2.0–2.5 mm for M4 fasteners) to avoid rounding the socket and to achieve a solid torque without over-tightening.
• Apply a light thread lubricant if you anticipate frequent disassembly, which helps extend screw life and maintain clamp force.
• Before use, inspect for any visible wear from prior use; although galvanized for durability, the integrity of threads is essential for reliable performance in future assemblies.
• Store with the included after-sale accessories in a dry, cool place to prevent corrosion or moisture-related damage to exposed surfaces.

What you gain with this purchase

• A ready-to-install, space-efficient fastener that delivers strong joint performance for miniature projects.
• Robust corrosion resistance from galvanized carbon steel, offering dependable service in typical workshop conditions.
• Clear value from a used, semi-finished component paired with an accessories package designed to support installation and future replacements.
