Strong and durable
Used them for heavy-duty switch assembly. No stripping on the Phillips head even under high torque. Very satisfied with the hardness.

Solid fasteners
Head fits well with a standard PH2 driver. Slight variance in the black oxide finish on a couple of screws, but functionally perfect.

Great length
120mm is hard to find in standard hardware stores. These fit perfectly through my chassis panels. Will buy again.

Good quality, slow shipping
Steel is hard and threads cut well into aluminum. Only giving 4 stars because shipping took longer than expected, but the product itself is great.

Perfect for my project
These screws are exactly what I needed for my metal enclosure build. The 120mm length is hard to find locally and the steel quality is excellent.
Q: Do you offer bulk discounts for larger orders?
A: Yes, please contact our sales team directly through the contact page for pricing on bulk quantities over 500 units.
Q: What driver size fits these screws best?
A: These screws are designed for a PH2 Phillips head driver. Using the correct size prevents cam-out and damage to the head.
Q: Is the thread running the full length of the screw?
A: Yes, these are fully threaded self-tapping screws from head to tip.
Q: Can these be used on aluminum profiles?
A: Yes, they are self-tapping and work well on aluminum. We recommend pre-drilling a pilot hole for best results.
Q: Are they rustproof for outdoor use?
A: The black oxide finish provides some corrosion resistance, but for harsh outdoor environments, we recommend applying additional coating.
