The M5x16 Hex Cylindrical Head screw is a compact metric fastener designed for precise, space-saving assemblies where a clean, low-profile fit matters. With a 5 mm nominal diameter and a 16 mm length, this screw provides reliable holding power in electronics, enclosures, brackets, and other compact hardware setups.

Why this screw stands out

• Low-profile cylindrical head offers smooth seating in tight panels and reduces snagging in crowded assemblies, delivering a neat, professional finish.
• Hex drive (Allen) enables secure tightening with commonly available hex keys, giving you confident torque control during installation.
• Metric M5 threading aligns with widely used components, making it a versatile choice for electronics racks, robotics frames, and DIY projects.
• Length of 16 mm is ideal for mounting through moderately thick materials or into threaded inserts where you don’t want the screw to protrude excessively.
• Compatibility works with through-holes, threaded holes, nuts, or threaded inserts designed for M5 hardware, expanding your fastening options across projects.

Ideal use cases

• Securing small enclosures, panels, and sensor brackets in robotics or automation projects.
• Mounting PCBs or components to chassis where a flush, unobtrusive fastener is preferred.
• Assembling hobbyist electronics, DIY 3D printer parts, or compact machinery where space is at a premium.

Installation tips

• Use an appropriately sized hex key to achieve a snug, controlled torque without over-tightening.
• Pair with a washer if distributing load on softer materials or when mounting larger panels to prevent indentation.
• Ensure the mating hole or insert is compatible with M5 threads to achieve optimal grip and longevity.
