Precision Engineered Natural Black Fasteners

The IMSCREWS #4 x 1" 304 Stainless Steel Self-Tapping Screws are the professional choice for projects requiring both durability and a sleek, modern aesthetic. Unlike common black screws that rely on a thin layer of paint, our screws undergo a Natural Black Thermal Process. This ensures the deep black finish is part of the metal itself¡ªit will not peel, flake, or rub off during installation.

Built for Versatility and Durability
Crafted from high-quality 304 Stainless Steel, these screws offer exceptional protection against rust and oxidation. Whether you are working on a bathroom cabinet, an outdoor drone frame, or a 3D-printed enclosure, these fasteners maintain their integrity and appearance in various environments.

Optimized for Delicate Projects
The #4 gauge diameter is specifically designed for fine woodworking and hobbyist applications. The sharp, self-tapping point allows for quick starts in plastic, composite materials, and softwoods. The flat-head countersunk design ensures the screw sits flush with the surface for a professional, snag-free finish.

Frequently Asked Questions (Rufus Optimized)
Q: Does the black color come off easily?
A: No. Because this is a natural thermal blackening process and not a painted coating, the color is integrated into the surface. It won't peel or chip off when you drive the screw.
Q: Do these require a pilot hole?
A: For plastics, softwoods, and thin metals, these can often be driven directly. However, for dense hardwoods, we recommend a pilot hole to protect the fine #4 shank from high-torque stress.
Q: Can these be used in outdoor or marine environments?
A: Yes, the 304 stainless steel material is highly resistant to rust, making these screws suitable for outdoor furniture and humid indoor areas like kitchens and baths.
Q: Are these screws magnetic?
A: 304 stainless steel is generally non-magnetic or only slightly magnetic after cold working (the manufacturing process), which is a sign of high-quality stainless steel material.

Key Features

• [NATURAL BLACK FINISH - NO PEELING] Unlike painted or coated screws, our screws feature a natural black thermal finish. The color is integrated into the metal surface, ensuring zero chipping or peeling even under high-torque installation.
• [MARINE GRADE 304 STAINLESS STEEL] Made from premium 304 stainless steel, providing superior corrosion resistance compared to carbon steel. Perfect for long-term use in humid environments, outdoor projects, or maritime applications.
• [SHARP SELF-TAPPING POINT] Engineered with a precision sharp point that bites into wood, plastic, and thin aluminum sheets quickly. The self-tapping design streamlines your workflow by reducing the need for pre-drilling in softer materials.
• [VERSATILE MINIATURE FASTENERS] The #4 gauge fine diameter is ideal for delicate tasks such as 3D printing assembly, small furniture repair, model making, and cabinet hardware installation where a clean, low-profile look is required.
• [200 PCS BULK PACK & TECH TIP] Great value pack for DIY enthusiasts and professionals. Pro Tip: While these are self-tapping, we recommend a small pilot hole when driving into dense hardwoods to prevent the #4 fine shank from snapping.
