Screw SCHROFF M3.0 x 8 nickel-plated 21100646

Nickel-plated SCHROFF screw, size M3.0 x 8 mm, designed for mechanical fastening in electronics and industrial enclosures. This fastener is intended for applications requiring a short M3 length with reliable thread engagement and improved corrosion resistance provided by the nickel plating. The screw is compatible with standard M3 threaded holes and nuts, and is suitable for mounting printed circuit boards, panels and small components where a compact, durable metal fastener is needed.

Advantages

The nickel plating increases surface hardness and provides protection against corrosion, extending service life in indoor industrial and electronic environments. The M3 x 8 size offers a balance between thread engagement and compact length, reducing the risk of protrusion while ensuring secure fastening. Manufactured to consistent dimensions, the screw provides repeatable fit and torque behaviour for assembly and maintenance tasks.

Suitable for

• Mounting printed circuit boards (PCBs) and electronic modules
• Securing panels and front plates in enclosures
• Fastening small mechanical components and brackets
• General-purpose assembly where an M3 x 8 metal fastener is required

Key specifications

• Thread size: M3.0
• Length: 8 mm (length measured from under head to tip)
• Surface finish: nickel-plated
• Material: metal (steel base)
• Corrosion resistance: improved due to nickel plating

How to use

Select a compatible M3 threaded hole or nut and align the components to be fastened. Use a suitable screwdriver or driver bit that matches the screw head recess (choose the correct head type for installation). Apply steady torque until the component is secured; avoid over-tightening to prevent thread or component damage. For repeated assembly, inspect threads and plating for wear and replace screws showing significant corrosion or deformation.

Usage recommendations

For optimal performance in electronic assemblies, use screws of the same finish and material to reduce the risk of galvanic corrosion. When fastening PCBs, consider using insulating washers or standoffs where electrical isolation is required and apply recommended torque limits for M3 fasteners to protect components and threaded inserts.
