Meet the Screw-M4x40-Hexagon socket head — a precise, dependable fastener crafted for reliable performance in compact assemblies. With an M4 diameter and a 40 mm length, it delivers a strong, secure grip where space is limited.

• Compact, standards-driven sizing: The M4 thread accommodates a wide range of brackets, panels, and fixtures common in electronics, DIY projects, and light machinery.
• Allen-key compatibility: The hexagon socket head accepts a standard Allen key, enabling accurate torque application and a clean, tool-friendly installation in tight or recessed spaces.
• Extended reach, solid hold: The 40 mm length provides ample bite for mounting thicker brackets or deeper holes, reducing the need for multiple fasteners.
• Reliable, removable fastener: Precisely machined threads engage smoothly, delivering consistent clamping force that’s easy to re-tighten during maintenance or adjustments.
• Versatile applications: Ideal for electronics enclosures, hardware for furniture and fixtures, robotics assemblies, and equipment housings where a low-profile, high-torque fastener is beneficial.

Practical guidance for best results: ensure hole alignment before threading, keep threads clean during assembly, and use the appropriate Allen key to avoid stripping. This screw is designed to deliver repeatable performance in everyday fastening tasks, making it a reliable choice when you need a precise M4x40 hex socket head.
