Product Technical Specifications
Enhance your assembly projects with IMSCREWS professional-grade M3 x 30mm self-tapping screws. These fasteners are engineered with a unique Integrated Washer Head (approximately 6.7mm diameter), which significantly expands the contact area. This design ensures even pressure distribution and prevents the screw head from pulling through or damaging fragile materials like plastic or soft woods.

Advanced Natural Black Technology
Tired of black screws that leave unsightly silver scratches after one use• Our screws undergo a Natural Black chemical conversion process. Unlike traditional painting or electroplating, this finish is part of the metal itself. It provides a sleek, professional matte appearance that is immune to peeling or chipping, making them the perfect choice for high-end electronic casings, automotive interiors, or black furniture hardware.

Durable 304 Stainless Steel Construction
Manufactured from authentic 304 Stainless Steel, these screws offer superior corrosion resistance compared to carbon steel or zinc-plated alternatives. Whether you are working on a humid outdoor project or a precision indoor repair, these screws maintain their integrity and appearance over time. The Type A Sharp Point and deep threads (22 TPI) ensure a secure and reliable hold.

Common Applications & Installation Tips
These M3 fasteners are highly versatile for DIY enthusiasts and professionals alike. Common uses include:
- Securing black plastic housings for electronics.
- RC car and drone component mounting.
- Detailed woodworking and cabinet hinge installation.
- Small appliance repairs.

Important Note: While the sharp point allows for direct driving into many materials, we highly recommend pre-drilling a pilot hole when using these screws on metal surfaces. This step preserves the thread integrity and ensures a flush, professional finish. Please note that this pack includes 50 screws; a Phillips driver bit is not included.

Frequently Asked Questions (FAQ)
Q: Will the black color scratch off during installation?
A: No. Thanks to our Natural Black treatment, the color is embedded into the material surface, not just a top coat. It will not peel or chip even under high friction.

Q: Are these screws suitable for outdoor use?
A: Yes, they are made of 304 Stainless Steel, which is highly resistant to rust and oxidation in outdoor and damp environments.

Q: Do I need to buy separate washers?
A: No, the washer is built into the head for a seamless, low-profile, and sturdy installation.
