Screw-M4x16-Hex Socket Pan Head

The Screw-M4x16-Hex Socket Pan Head is a compact, dependable fastener designed for precise assemblies where a clean, low-profile finish matters. With a metric M4 thread and a 16 mm length, it fits a wide range of electronics, enclosures, brackets, and light-machine applications that require a reliable bite and easy installation.

• 
  Size and drive: M4 x 16 mm, hex socket drive (Allen) for secure engagement and a flush tool interface.
• 
  Head profile: Pan head offers a broad bearing surface to evenly distribute clamping force and minimize material deformation on softer substrates.
• 
  Material compatibility: Suitable for tapping into metal, durable plastics, and thin panels where a clean, visible fastener is acceptable.
• 
  Precision and consistency: Tight dimensional tolerances ensure reliable cross-project performance and repeatable results.

Why this size matters: 4 mm diameter is a common choice for lightweight assemblies, giving strong grip without excessive protrusion. The 16 mm length strikes a balance between secure clamping and keeping the fastener unobtrusive in compact builds—ideal for electronics enclosures, camera housings, DIY brackets, and 3D printer assemblies where space is at a premium.

Use cases:

• Mounting chassis brackets or covers on electronics enclosures and computer cases.
• Attaching panels in small machinery or hobby projects where a clean, finished look is desired.
• Assembling aluminum extrusions or plastic components that require a robust, repeatable fastener.

How to use:

• Pair with a corresponding tapped hole or nut that matches the M4 thread for secure installation.
• Engage with a hex key sized for standard M4 hex sockets, then tighten to the needed clamping force with controlled torque.
• For plastic or softer materials, consider using a washer or a thread insert to protect the surface and improve load distribution.

Distinctive advantages of the Screw-M4x16-Hex Socket Pan Head include its clean, professional appearance and practical head geometry that provides reliable seating without excessive height. It’s a purposeful choice for builders who value precise fit, straightforward assembly, and a neat final look in every project.
