Precision Fasteners for Delicate Projects

When your project demands precision, aesthetics, and durability, standard hardware store screws often fall short. IMSCREWS #4 x 1/4" Matte Black Stainless Steel Screws are engineered for luthiers, makers, and DIY enthusiasts who need a reliable fastening solution for thin materials.

The "Natural Blackening" Advantage

Unlike cheap black-zinc screws that rust, or painted screws where the black chips off, our screws undergo a professional Chemical Blackening Process. This modifies the surface of the 304 Stainless Steel to a matte black finish without adding thickness.

• No Peeling: The color is integral to the steel, not a coating.

• No Clogging: Driver bits fit perfectly without paint buildup.

• No Rust: Retains the superior corrosion resistance of 304 Stainless Steel.

Key Features:

• True 304 Stainless Steel: Safe for humid environments, outdoor furniture, or marine electronics.

• Stealth Look: The matte finish blends seamlessly with black plastic, antique wood, and guitar pickguards.

• Ultra-Short 1/4" Length: Specifically designed for shallow depths (e.g., jewelry boxes, backplates) to prevent piercing the reverse side.

Technical Specifications:

• Material: 304 Stainless Steel (18-8)

Common Questions Answered (FAQ):

Q: Is the black finish painted• Will it flake off?

A: No. These screws feature a "Natural Blackened" finish chemically converted into the surface. It is not paint and will not chip, peel, or flake.

Q: Are these magnetic?

A: 304 Stainless Steel is technically non-magnetic. However, the cold-heading manufacturing process can induce slight magnetism. They are far less magnetic than carbon steel but may hold slightly to a magnetic driver.

Q: Will these rust outdoors?

A: No. They are made from 304 Stainless Steel, offering excellent rust resistance for both indoor and outdoor use.

Q: What size drill bit for pilot holes?

A: For hardwoods, we recommend a 1/16" or 5/64" bit. For softwoods or plastics, a pilot hole is often not needed due to the sharp point.
