Good quality, fast shipping

The 304 stainless steel feels solid and resists rust well. I used them for an outdoor project. Only giving 4 stars because the packaging was slightly dented, but the screws were fine.

Perfect for industrial use

Ordered the M6 bulk pack for our assembly line. The quality is consistent, and the hex sockets are deep enough to prevent stripping. Great value for wholesale.

Solid construction

Very sturdy screws. The threads are clean and cut easily into aluminum. I wish the box had dividers for different sizes, but overall a good purchase.

Exactly as described

Needed specific M4 mushroom head screws for a custom electronics enclosure. These fit perfectly and look very professional with the polished finish.

5 FAQ

Q: Are these screws suitable for marine environments?

A: Yes, 304 Stainless Steel offers good corrosion resistance for most marine applications, though 316 grade is recommended for direct saltwater immersion.

Q: Is an Allen key included in the package?

A: No, the bulk packages contain only the screws. Tools must be purchased separately to match the specific hex socket sizes required.

Q: Do you sell individual sizes or only mixed packs?

A: We offer both mixed variety packs and bulk boxes containing a single specific size (e.g., only M5). Please select your preference from the dropdown menu.

Q: What is the thread pitch for the M8 size?

A: The M8 screws feature a standard coarse thread pitch of 1.25mm unless otherwise specified in a custom order.

Q: Can these withstand high temperatures?

A: 304 Stainless Steel maintains its structural integrity up to approximately 870°C (1600°F) for intermittent service, making them suitable for many high-heat applications.
