Excellent corrosion resistance

Using these in a humid workshop environment. No signs of rust after three months. The finish is smooth and professional.

Solid hardware

Very sturdy screws. The headless design is perfect for applications where space is tight. Would recommend keeping the box organized as the small M2 screws can get lost easily.

Perfect for my CNC projects

These grub screws are exactly what I needed. The hex socket is well-defined and didn't strip even under high torque. The 304 stainless steel feels durable.

Good quality, varied sizes

Great assortment kit. I used the M4 and M5 sizes primarily. The flat point sits flush against the shaft as expected. One size was slightly low in quantity, but overall good value.

Precise threading

The threads engage smoothly without cross-threading. I appreciate the consistent quality across all the different metric sizes included in the set.

5 FAQ

Q: Does the kit include the Allen keys needed to install them?

A: This specific screw set does not include Allen keys. You will need to use your existing metric hex key set corresponding to sizes M2 through M8.

Q: What is the thread pitch for the M6 screws?

A: The M6 screws feature a standard coarse thread pitch of 1.0mm, which is the industry standard for general machine screws.

Q: Can I get a VAT invoice for this purchase?

A: Yes, as mentioned in the product description, we provide special VAT invoices. Please request this at checkout or contact our support team after your order is placed.

Q: Are these screws suitable for outdoor use?

A: Yes, being made of 304 Stainless Steel, they offer good corrosion resistance for most outdoor applications, though marine-grade 316 might be preferred for direct saltwater exposure.

Q: Is the flat point hardened?

A: The screws are heat-treated to ensure durability and prevent deformation during tightening, making them suitable for securing heavy-duty components.
