Screw (Linsenschraube) SCHROFF M6 model 21100650, zinc-plated black

SCHROFF Linsenschraube M6 model 21100650 is a zinc-plated black machine screw designed for fastening components where an M6 threaded fastener is required. The screw provides a uniform black finish and corrosion protection from the zinc plating, making it suitable for general assembly and enclosure mounting in electronics racks and equipment. It is manufactured for reliable mechanical connection in industrial and electronic applications.

Advantages

The zinc-plated black surface offers corrosion resistance and a consistent aesthetic appearance across metal chassis and enclosures. The lens-head (countersunk-profile) shape provides a clean contact area that reduces the likelihood of snagging and distributes clamping force evenly. Manufactured to typical industrial tolerances, the screw is compatible with standard M6 threaded holes and nuts, enabling straightforward installation and replacement.

Suitable for

• Mounting panels and enclosures in electronics racks
• Securing components to metal frames and chassis
• General mechanical assembly requiring M6 fasteners
• Applications where a black, corrosion-resistant finish is preferred

Key specifications

• Thread size: M6
• Head style: lens head (rounded/countersunk profile)
• Plating/finish: zinc-plated, black
• Intended use: machine screw for fastening metal components
• Typical material: steel (zinc-plated for corrosion protection)

How to use

Select an appropriate M6 threaded hole or nut to match the screw's thread size. Insert the screw through the component or into the mating part and tighten using the correct screwdriver or driver bit for the head style until secure. Apply torque within the recommended limits for M6 steel screws to avoid stripping threads or deforming the head; hand tools or torque-controlled drivers may be used depending on assembly requirements. For repeated installations, inspect the plating for wear and replace screws that show significant corrosion or thread damage.

Recommendations for use

Store screws in a dry environment to preserve the zinc-plated finish. Use appropriate torque settings for M6 fasteners and avoid over-tightening to maintain mechanical integrity. When used in environments with aggressive chemicals or high humidity, consider additional corrosion protection or periodic inspection.
