Solid fasteners

Great screws for the price. The M8 size is very sturdy. I deducted one star because shipping took a bit longer than expected, but the product itself is flawless.

High quality stainless

Used these for an outdoor garden structure. They have held up well against rain and humidity without any corrosion. The drive depth is sufficient for high-torque application.

Saved me time

The integrated washer feature is a game changer for my furniture repair business. No more fumbling with separate washers. The 304 steel is genuine and strong.

Exactly as described

These fit perfectly into my CNC machine frames. The pan button head looks professional, and the washer prevents loosening under vibration. Will definitely reorder.

Good value for bulk buying

Bought a mixed pack of M3 and M4 for electronics projects. The heads are clean and the hex sockets don't strip easily. One box had a few slightly bent screws, but overall great value.

Perfect for industrial use

Ordered the M6 size for our assembly line. The integrated washer saves us a step during installation, and the steel quality is top-notch. No signs of rust after three months in our warehouse.

5 FAQ

Q: Are these screws compatible with metric Allen keys?

A: Yes, these screws feature a standard hex socket drive designed specifically for metric Allen keys corresponding to each screw size.

Q: Is there a warranty if the threads are stripped upon arrival?

A: Yes, we offer a full replacement guarantee for any manufacturing defects, including damaged threads, reported within 30 days of delivery.

Q: Does the bulk box come divided by size?

A: If you order a mixed-size pack, the box includes internal dividers to keep sizes separate. Single-size bulk orders come in a uniform compartment.

Q: Can I use these in a marine environment?

A: While 304 Stainless Steel offers good corrosion resistance, we recommend 316 Stainless Steel for direct saltwater or harsh marine environments to ensure maximum longevity.

Q: What is the tensile strength rating for the M8 screws?

A: Our 304 Stainless Steel screws generally meet A2-70 standards, providing a minimum tensile strength of 700 MPa for the M8 size.
