Perfect fit for my machinery

These brass grub screws are exactly what I needed for a repair job on some vintage equipment. The socket depth is consistent, and they tightened down without stripping. Great quality for the price.

Reliable standard parts

I run a small workshop and go through these constantly. These RoHS compliant screws are consistent in thread quality. No issues with cross-threading during installation.

Top repurchase indeed

The description says top repurchase and I can see why. We use these for securing knobs on musical instruments. They hold well without marring the metal shafts. Highly recommended.

Excellent for non-magnetic applications

Needed non-magnetic screws for a sensitive sensor assembly. These brass set screws worked perfectly. The headless design allows for a flush finish which was critical for our setup.

Good quality, fast shipping

Ordered the M4 size for a custom electronics project. The brass is soft enough to not damage the shaft but holds tight. Delivery was quicker than expected. Would buy again.

Solid choice for general use

Bought a mixed pack of sizes. Most were perfect, though one M6 screw had a slightly rough thread start. Still usable, and the rest of the batch was flawless. Good value overall.

5 FAQ

Q: Can I get a certificate of compliance for the RoHS standard?

A: Yes, all our RoHS standard products comply with regulations. You can request a digital copy of the compliance certificate by contacting our support team with your order number.

Q: What is the thread length for the M6 size?

A: For our standard M6 brass grub screws, the full thread length typically matches the nominal diameter options available (e.g., 6mm, 8mm, 10mm). Please select the specific length required at checkout.

Q: Is the brass material suitable for outdoor use?

A: Brass offers good corrosion resistance, making it suitable for many outdoor applications. However, for highly saline or extreme chemical environments, additional coating or stainless steel might be preferred.

Q: Are these screws compatible with aluminum shafts?

A: Yes, brass is softer than aluminum, which helps prevent galling and damage to the aluminum shaft when tightening. It is a common and safe combination.

Q: Do these screws come with an Allen key included?

A: No, the screws are sold separately without tools. However, they fit standard metric Allen keys corresponding to their size.
