Hexagon socket head M5x20 screw with washer assemblies

Designed for precision and reliability in compact assemblies, the Hexagon socket head M5x20 screw with washer assemblies delivers a streamlined, ready-to-use fastening solution. This single-unit fastener combines a hex socket head cap screw with integrated washers, ensuring even load distribution and surface protection right out of the box.

What makes this screw stand out

• M5x20 size joins a 5 mm diameter with a 20 mm length, compatible with standard metric threaded holes and common panel thicknesses.
• Hexagon socket head design (Allen drive) enables precise torque control in tight spaces, reducing the risk of cam-out and over-tightening.
• Washer assemblies provide controlled bearing pressure, safeguard delicate surfaces, and prevent pull-through, all without needing separate washers.
• Integrated washer reduces parts count and speeds up assembly—ideal for DIY projects, hobby electronics, and light-to-medium mechanical builds.
• Versatile across applications where a secure, flush-fastening is essential, from enclosures and dashboards to small robotics and machine frames.

Ideal use cases

Use this M5x20 with washer assemblies when you need reliable clamping in constrained spaces. It’s particularly well-suited for mounting panels to frames, attaching components to enclosures, or securing modular housings where surface protection and consistent pressure matter. The one-piece washer solution minimizes misalignment during insertion and helps maintain a neat, professional finish.

Installation tips

Pair with a matching Allen key and tighten according to the material and joint thickness you’re working with. For vibration-prone setups, consider periodic checks to maintain clamping force, and apply an appropriate threadlocker only if your design calls for it.
