Questions about this product
- What sizes are in this 100-piece screw set?
- The assortment spans M2, M2.5, M3, M4, M5, M6, and M8, all fully threaded. The exact count per size isn't fixed, with smaller sizes usually included in larger numbers. It's an assorted box, so it's handy for general repair and assembly stock.
- How strong is Grade 12.9 alloy steel?
- Grade 12.9 is the top strength class for these socket cap screws, hardened to roughly 39 to 44 HRC. That makes them suited to high-stress, high-torque joints. The hex socket drive lets you really crank them down in tight spots.
- Will the black oxide finish stop rust?
- Black oxide cuts glare and gives some corrosion resistance, but it's a light coating, not heavy rustproofing. For damp or outdoor use, add oil or keep them dry. Indoors and in machinery, they hold up well.
