Fast shipping and great product

Arrived quickly and well-packaged. The M4 size was perfect for assembling my garden furniture. Will definitely buy again when I run out.

Good value, sharp threads

Very sharp threads that cut through hardwood easily. I deducted one star only because the box labeling was slightly unclear on the specific length mix, but the quality is top-notch.

Solid construction hardware

Great screws for general woodworking. The flat head sits flush perfectly. Would have given 5 stars if they came in a resealable bag instead of a cardboard box.

Perfect for marine applications

Used these on a small boat repair. After a few months of exposure to salt water, there is absolutely no sign of corrosion. Highly recommended for any marine environment.

Heads don't strip easily

I've had issues with cheap screws where the Phillips head strips immediately. These held up well under high torque from my drill. Very satisfied with the durability.

Excellent quality stainless steel

These screws are exactly what I needed for my outdoor deck project. The 304 stainless steel ensures they won't rust, and the self-tapping feature made installation incredibly fast.

5 FAQ

Q: Are these screws suitable for use in pressure-treated lumber?

A: Yes, 304 stainless steel is highly resistant to the chemicals found in pressure-treated wood and prevents corrosion.

Q: Is this product sold as a mixed size pack or single size?

A: You can select specific sizes (M3, M4, etc.) from the dropdown menu. Each option contains 100 pieces of that specific diameter, with varying lengths included.

Q: Can these be used with an impact driver?

A: Yes, the cross recess is designed to withstand standard impact drivers, though we suggest using the correct bit size to avoid cam-out.

Q: What is the difference between M4 and M5 sizes?

A: The number refers to the nominal outer diameter in millimeters. An M4 screw is 4mm wide, while an M5 screw is 5mm wide. Please choose based on your project requirements.

Q: Do I need to pre-drill holes before using these self-tapping screws?

A: While they are self-tapping, we recommend pre-drilling a pilot hole for hardwoods or when working near the edge of the material to prevent splitting.
