This is a set of 100 M3x16mm socket head cap screws, manufactured from 12.9 grade alloy steel with a black oxide finish. They are intended for various fastening applications, especially where high strength and a low profile head are required. Overall, they appear to be a well-made and useful set of fasteners.
Pros
• The 12.9 grade alloy steel provides exceptional tensile strength, suitable for demanding applications.
• The black oxide finish offers a degree of corrosion resistance and a sleek, professional appearance.
• The socket head cap design allows for high torque fastening in confined spaces.
• Having 100 pieces in the set provides a good quantity for projects or repairs.
Cons
• The black oxide finish is primarily cosmetic and offers limited long-term corrosion protection compared to stainless steel.
• M3 size may be too small for some applications requiring larger, more robust fasteners.
Verdict
This set of M3 screws is a good choice for electronics work, 3D printing projects, or other applications where small, strong fasteners are needed. The high-strength steel and socket head design make them a reliable option for various fastening tasks.
