Perfect for my electronics project

These screws fit perfectly into my chassis. The stainless steel quality feels premium and the Phillips drive didn't strip easily.

Good value but tight fit

Overall good quality. The M5 screws were slightly tight on some threads, but nothing a tap couldn't fix.

Corrosion resistant

Used these for an outdoor fixture. No signs of rust after a few months of exposure to rain.

Great assortment kit

Having M3 through M6 in one box is very convenient. Saves me from ordering multiple packs for different sizes.

5 FAQ

Q: What is the length of the M4 screws?

A: The kit includes assorted lengths for each diameter. Please refer to the detailed size chart in the product images.

Q: Are these screws compatible with aluminum threads?

A: Yes, 304 stainless steel is generally compatible with aluminum, but we recommend using anti-seize compound to prevent galvanic corrosion.

Q: Is the steel magnetic?

A: 304 stainless steel is generally non-magnetic, though slight magnetism may occur due to cold working during manufacturing.

Q: Do you offer bulk pricing for over 50 kits?

A: Yes, please contact our sales team directly for bulk order discounts and shipping quotes.

Q: Does this kit include a screwdriver?

A: No, this package contains only the screws. You will need to provide your own Phillips screwdriver.
