Professional grade performance

I use these daily on job sites. The hardened steel prevents snapping under high torque, and the coarse thread grips gypsum board securely. Highly recommended.

Best bulk deal I've found

Free shipping made this an incredible deal. The screws are consistent in size and quality. No jams in my electric screwdriver. Excellent product.

Perfect for drywall installation

These screws drove straight into the studs without stripping. The black finish helps them blend in perfectly with the board. Great value for the price.

Easy to use for beginners

As someone new to home repair, I found these very forgiving. The bugle head sits flush without tearing the paper face of the drywall. Will buy again.

Solid choice for hanging shelves

Bought these to anchor brackets into studs behind drywall. They are strong and reliable. The only reason for 4 stars is the packaging was slightly damaged upon arrival.

Good quality, fast shipping

Used these for a bedroom renovation. They hold well and the self-tapping feature saved me time pre-drilling. One box had a few bent ones, but overall satisfied.

5 FAQ

Q: Can I use these with a standard cordless drill?

A: Yes, these screws have a standard PH2 Phillips head and work perfectly with any standard cordless drill or impact driver equipped with a #2 bit.

Q: Does the black coating resist rust outdoors?

A: The black phosphate coating offers basic corrosion resistance for indoor use. For outdoor or high-moisture applications, please consider our galvanized or stainless steel screw options.

Q: How many screws are approximately in the 1kg box?

A: The count varies slightly by length, but a 1kg box typically contains between 400 and 500 screws depending on whether you choose the 25mm or 50mm variety.

Q: What size drill bit do I need for the pilot hole?

A: Since these are self-tapping, you generally do not need a pilot hole when driving into soft wood or gypsum. If using hard wood, a small 2mm pilot hole may help prevent splitting.

Q: Are these screws suitable for metal studs or just wood?

A: These specific screws feature a coarse thread designed primarily for wood studs and gypsum board. For metal studs, we recommend our fine-thread drywall screws for better grip.
