#6 x 1-1/4 Black Drywall Screws 4020 pcs - Coarse Thread, Sharp Tip

In this review the focus is on a high-volume pack of #6 x 1-1/4 black drywall screws aimed at installers, hobbyists, and anyone who needs reliable fasteners for drywall, wood, and galvanized structures. The single biggest reason to buy is straightforward: these screws combine a sharp, self-drilling tail and clear, uniform threads that make driving fast and reduce splitting, so projects move quicker with fewer pilot holes and less material damage.

Key Features

• Material: Made of iron, these screws suit projects involving galvanized structures where a strong basic metal fastener is required.
• Head design: The standard cross channel steel truss head provides a broad bearing surface for secure clamping and helps prevent the head sinking into drywall or wood.
• Thread quality: Clear, tidy coarse threads reduce driving resistance and improve pull-out resistance, which helps the fastener hold without causing cracking.
• Tip design: The sharp tail tip is easy to drill into common substrates without pre-drilling, saving time on routine installations.
• Finish and feel: The black finish and smooth screw section are free of burrs, which helps the driver bit engage cleanly and reduces cam-out.
• Size consistency: At screw diameter #6 (3.5mm) and length 1-1/4 in, these screws work as a standard choice for attaching drywall and light trim where that length is appropriate.

Who It's For

These screws are best for drywall installers, carpenters, and DIYers who need a large quantity of dependable fasteners for routine hanging, furring, and light structural tasks. The pack size and reliable tip make them practical for continuous work where stopping to drill pilot holes would be inefficient.

They are less suitable for applications demanding corrosion-resistant stainless steel or specialized coatings for exterior exposure near salt or chemical environments. For very heavy timber or structural framing that requires larger diameters or longer lengths, a heavier duty screw would be a better match.

Pros & Cons

Pros

• High-quality iron construction gives a solid feel and good performance for interior and galvanized structure tasks.
• Sharp tail tip allows for quick drive-in without pre-drilling in most drywall and wood uses.
• Clean, uniform threads and smooth shank reduce resistance and help prevent cracking of materials.
• Truss head and cross channel design improve bit engagement and holding surface.

Cons

• Iron construction with a basic black finish is not a substitute for stainless or premium corrosion-resistant coatings for harsh outdoor use.
• Size is fixed at #6 x 1-1/4 in, so projects needing longer or thicker screws require a different SKU.
