Good variety pack

Great assortment of sizes from M2 to M8. The washers fit perfectly. I deducted one star only because the M2 screws were slightly fewer in number than expected, but overall a solid purchase.

Excellent quality stainless steel

These screws are exactly what I needed for my electronics project. The 304 stainless steel feels very durable and the finish is smooth. No signs of rust after a month of use in my workshop.

Decent but mixed lengths

The quality of the steel is good, but the set includes various lengths for each diameter which wasn't entirely clear in the description. Make sure to check the specific length requirements for your project before buying.

Perfect for furniture repair

Used these to reassemble a wooden chair. The countersunk head sits flush with the surface, giving a very professional look. The Phillips drive grips well without stripping.

Reliable for outdoor projects

I used the M6 and M8 sizes for a garden trellis. They have held up well against rain and humidity so far. The spring washers provide good tension to keep everything tight.

5 FAQ

Q: What is the thread pitch for the M4 size?

A: The M4 screws in this set follow the standard metric coarse thread pitch, which is 0.7mm.

Q: Does the kit come with a storage case?

A: Yes, the set comes in a compartmentalized plastic organizer box to keep the different sizes and components separated.

Q: Is the head angle standard 90 degrees?

A: Yes, the countersunk heads are manufactured with a standard 90-degree angle, compatible with most standard countersink bits.

Q: Are these screws magnetic?

A: 304 Stainless Steel is generally non-magnetic or very weakly magnetic. These screws should not stick strongly to a standard magnet.

Q: Can these be used in saltwater environments?

A: While 304 stainless steel has good corrosion resistance, it is not recommended for direct, prolonged exposure to saltwater. For marine environments, 316 stainless steel is preferred.
