Finished in a distinctive blue-and-white zinc plating, they’re packed as an after-sales spare parts package designed to be ready for re-use when you need quick, reliable fasteners that disappear beneath the surface.

Why these screws stand out

• Flush, countersunk head design for a clean surface and seamless appearance in enclosures, panels, and furniture.
• Hex socket drive (Allen) for secure tightening with minimal cam-out, even in tight spaces.
• M5 × 12 mm dimensions match common mounting holes and hardware in electronics, equipment housings, and DIY projects.
• Blue and white zinc plating delivers durable corrosion resistance while making the screws easy to identify in mixed-component kits.
• Used condition—professionally inspected and ready for reuse, offering a practical, budget-friendly option for ongoing maintenance and repairs.
• After-sales spare parts package—part of a dedicated kit so you can quickly stock up on trusted fasteners for future servicing.

Ideal use cases

These screws are well-suited for replacing worn fasteners in:

• Electronics and computer enclosures, where a flush finish helps with heat management and aesthetics
• 3D printer frames and robotics projects, providing dependable mounting without protruding heads
• Kitchen and appliance panels, automotive interior trim, and lightweight furniture assemblies
• Maintenance kits for workshops and fab rooms, keeping essential hardware on hand

How this helps you solve common problems

• Cost-effective maintenance—reliable used screws that perform like new parts without paying premium prices.
• Quick replacements—a ready-to-use package so you don’t have to hunt for individual fasteners.
• Consistent finish—the blue-white zinc coating helps identify these screws in a mixed hardware set while providing corrosion resistance for regular use.

Tips for best results

• Use an appropriately sized hex key to install; start by threading by hand to prevent cross-threading.
• Avoid overtightening to preserve the integrity of soft materials and the screws’ seating flush with the surface.
• Store in a dry, labeled container as part of your spare-parts inventory to keep them organized and ready for the next repair.
