Mounting Screws and Stand-offs Alphacool M3x4 with M3 Internal Thread, 6 mm Spacer (Alphacool 13461)

Alphacool M3x4 mounting screws with M3 internal-thread stand-offs and 6 mm spacers form a compact fastening set intended for secure mechanical assembly in PC builds. The set combines M3x4 screws with matching stand-offs that provide a fixed 6 mm separation between mounted parts. It is designed to attach water-cooling blocks, small brackets, printed circuit boards and similar components where standardized M3 fastening and precise spacing are required.

Advantages

The kit delivers precise M3 threading compatibility and consistent 6 mm spacing to ensure repeatable alignment of components. Metal construction offers mechanical stability for small loads and frequent assembly/disassembly. Using standardized M3 dimensions simplifies compatibility with many PC accessories, mounting plates and cooling hardware, reducing the need for custom fasteners or spacers.

Suitable for

• Mounting water-cooling blocks and pump brackets in PC water-cooling loops
• Securing small PCBs, controller boards and adapter modules
• Attaching brackets, adapter plates and fan/radiator accessories
• General-purpose spacers and stand-offs in custom PC mods and electronics enclosures

Key specifications

• Fastener thread size: M3
• Screw length: 4 mm (threaded portion specified as M3x4)
• Stand-off internal thread: M3
• Stand-off separation (spacer height): 6 mm
• Material: metal fasteners and stand-offs (conductive)

How to use

Select compatible holes or threaded points on the component and the mounting surface that accept M3 fasteners. Insert the M3x4 screws through the component or into the standoff as required, then engage the M3 internal thread of the stand-off and tighten until seated. Ensure the 6 mm stand-off provides the intended clearance between parts and avoid over-tightening to prevent thread damage or deformation of thin components. For assembly where electrical isolation is required, verify whether metal spacers are acceptable or additional insulating washers are needed.

Usage recommendations

Use a correctly sized M3 screwdriver or hex driver and apply moderate torque. When fastening PCBs or delicate components, support the board and tighten incrementally to avoid bending. If electrical insulation is necessary, add non-conductive washers or use insulating stand-offs instead of metal ones.
