Good Value

Solid screws for the price. One head stripped slightly under high torque, but overall satisfied.

Perfect Fit

Exactly what I needed for my electronics project. Threads cut cleanly into the aluminum chassis.

Solid Coating

The black oxide coating looks professional. Good grip with a PH2 driver on the M4 sizes.

Great Quality Screws

Used these for a PC case mod and they fit perfectly. The black finish matches my components well.

5 FAQ

Q: Are these screws made of stainless steel?

A: No, these are made of carbon steel with a black oxide finish for corrosion resistance.

Q: Is there a bulk discount available?

A: Yes, please contact our sales team directly for pricing on orders over 50 units.

Q: Is the black oxide finish rust resistant?

A: Black oxide offers mild corrosion resistance. For outdoor use, we recommend additional coating.

Q: What driver bit size should I use?

A: We recommend PH1 for M2-M3 and PH2 for M4-M6 to prevent stripping.

Q: Do you sell these in M1 size?

A: Currently we stock sizes ranging from M2 to M6. M1 is not available at this time.
