*USED* Inner hexagon socket countersunk head screw M5x16

Used M5x16 Countersunk Head Socket Screw with an inner hex (Allen) drive offers a compact, flush-finishing fastening solution for precise assemblies. The countersunk head allows the screw to sit level with the surface, delivering a clean, professional look in tight spaces.

This listing features a single used fastener suitable for projects where budget-friendly, reliable hardware is needed without sacrificing alignment or appearance. The M5 thread diameter and 16 mm length make it a versatile choice for small enclosures, metal brackets, and hobbyist builds.

Key features

• Drive type: Inner hex (Allen) socket for secure, tool-friendly installation
• Head style: Countersunk (flat) head to sit flush against surfaces
• Size: M5 x 16 mm, a common choice for lightweight frames and enclosures
• Condition: Used — may show signs of previous use; suitable for non-critical or budget-conscious projects

Ideal use cases

• Electronic enclosures and control panels that require a low-profile fastener
• DIY furniture repair or assembly where a flush finish matters
• Small metal brackets, supports, and frames in hobbyist builds (3D printer frames, robotics, RC projects)
• Repairs or replacements for missing or damaged screws in existing assemblies

Practical guidance

• Ensure you have a pre-tapped M5 hole or a matching nut for secure threading
• Check seating depth to guarantee the head sits flush; a countersunk seating misalignment can affect performance
• Inspect the thread portion for wear before reuse; replace if threads are damaged to avoid cross-threading
• Best paired with matching M5 hardware to maintain consistent finish and load distribution
