What you get

• 1 × M6 × 25 mm hex socket cylindrical head screw
• 1 × matching spring washer

Ideal use cases

• Equipment enclosures, control panels, and instrument housings where a low‑profile fastener is beneficial
• DIY projects and hobby electronics setups requiring a dependable, vibration‑resistant connection
• Maintenance or refurbishment of machinery and fixtures that use standard M6 hardware

Installation tips

• Verify hole alignment and material thickness to ensure the 25 mm length provides full thread engagement without protrusion.
• Use the hex key that matches the socket size firmly to avoid stripping the hex recess—apply steady, even torque.
• For added security in high‑vibration environments, consider pairing with a suitable thread locker after confirming compatibility with the materials involved.

Compatibility and considerations

Best suited for light‑to‑medium duty assemblies common in mechanical semi‑finished products and standard fastening tasks. As a USED component, inspect for any wear or minor surface imperfections that do not affect fit or function before installation.
