USED Inner Hexagon Cylindrical Head Black Zinc Plated Screw — KIT_M4 8 pieces

Designed for reliable, low-profile assemblies, this eight‑piece set features M4 screws with an internal hex (Allen) drive and a cylindrical head. The black zinc plating adds corrosion resistance, helping these fasteners stand up to longer-term use in a variety of environments. As a pre-owned kit, it offers practical value for budget-conscious projects without compromising on fit and performance.


  • 8-piece M4 set of inner hex cylindrical head screws, ready for immediate use in your builds.

  • Internal hex (Allen) drive provides a secure torque grip, reducing cam-out in tight spaces.

  • Cylindrical head sits flush or slightly proud, delivering a clean, streamlined appearance in assemblies where profile matters.

  • Black zinc plating delivers improved corrosion resistance compared to plain steel, making these suitable for hobby, electronics enclosures, and light-duty equipment.

  • After-Sale KIT packaging hints at practical, on-hand fasteners ready to support ongoing projects or replacements.

Ideal use cases include electronics enclosures, 3D printer assemblies, computer or networking equipment housings, robotics projects, and light furniture or fixture installations where a durable, low-profile fastener is preferred.

Why choose a used set? If you’re restoring equipment, building on a budget, or stocking a parts bin for quick replacements, this eight‑pack offers the right combination of size, head geometry, and finish without paying for new hardware. The inner hex drive helps you maintain consistent torque with a standard hex key, even in confined spaces where a screwdriver would struggle.

Practical tips for best results: choose the hex key sized for typical M4 socket screws, align the screw with tapped holes before turning, and apply steady pressure to avoid cross-threading. While this is a used set, it’s well-suited for non-critical assemblies and hobby projects where appearance and function matter more than pristine new‑part perfection.

Keep this 8‑piece M4 inner hex cylindrical head screw set on hand for quick repairs, ongoing builds, or as a cost-effective upgrade to your hardware inventory.
