IMSCREWS #4 × 1" 304 Stainless Steel Flat Head Wood Screws

Deep Grip for Delicate Projects

The IMSCREWS #4 x 1" Black Stainless Screw fills a unique gap in your toolbox: it offers the length of a standard deck screw but with the precision thinness of a micro-fastener.

Why Use #4 x 1 Inch?

• Fixing "Stripped" Holes: If a 1/2" or 3/4" screw has stripped out the wood, use this 1" screw to bite into fresh, solid wood deeper in the hole.

• Thick Material Assembly: Perfect for attaching 1/2" thick wooden trims where a shorter screw wouldn't reach the base.

• Edge Fastening: Safe to use near the edge of thin boards where a #6 screw would split the wood.

Technical Specs:

• Material: 304 Stainless Steel (18-8)

• Finish: Natural Matte Black (Non-Painted)

• Size: #4 x 1 Inch (2.9mm x 25mm)

• Drive: Phillips #1

• Important Installation Advice:

This is a slender screw. Do not use an Impact Driver. High torque will snap the head. Always drill a pilot hole (1/16") in hard materials and use a hand screwdriver or a drill on a low clutch setting.

Package Includes:

50 x Long Thin Black Screws (#4 x 1")

Key Features

• [EXTRA REACH: 1 INCH LENGTH] Designed for applications requiring deep penetration without the bulk of a thick screw. The 1" (25mm) length allows these #4 screws to pass through thicker panels (up to 1/2") and still grip the substrate firmly. Ideal for mounting spacers, thick backplates, or wooden trim.
• [ANTI-SPLIT THIN PROFILE] With a standard #4 thread diameter (approx 2.9mm), these screws are significantly thinner than standard #6 or #8 screws. This slender profile prevents splitting when fastening near the edge of wood, making them perfect for delicate antique restoration and model making.
• [MARINE GRADE 304 STAINLESS] Engineered for longevity. Unlike carbon steel that rusts internally, our screws are made from solid 304 Stainless Steel (18-8) with a Chemical Matte Black finish. They offer permanent rust resistance for outdoor trellises, boat interiors, or humid environments.
• [CRITICAL INSTALLATION TIP] Prevent Snapping: Due to the high length-to-thickness ratio of #4 x 1" screws, torque resistance is lower than short screws. We strongly recommend drilling a 1/16" or 5/64" pilot hole, especially in hardwoods (Oak/Maple), and driving slowly to avoid snapping the head.
• [NATURAL BLACK FINISH] The matte black color is chemically converted into the steel surface, ensuring no paint buildup clogs the Phillips drive. Features a standard Flat Countersunk Head (82¡ã) for a flush, professional finish. Package: 50 Pcs.
