Viti a testa cilindrica M4-0.7 x 8 mm | Testa svasata con esagono incassato | Filettatura completa | Acciaio inossidabile 316 (800 / confezione)

Finally got around to using these on a jig I was building and the hex socket drive made installation much easier than slotted screws. The 316 stainless feels solid and corrosion-resistant, which is exactly what I needed for a damp workshop environment.

For a full package of 800, these 316 stainless M4s are a solid buy—the flat heads sit flush in my jigs without any wobble, and the hex socket grabs the Allen key clean every time. Corrosion resistance isn't something I'll test for years, but the threading cut perfectly into aluminum without strippin

The hex socket drive sits nice and flush, which made tightening them into a tight corner on my tooling rig way easier than I expected. 316 stainless feels solid, no stripping after a dozen insertions. Only gripe is the 800-count box takes up more drawer space than I'd like, but that's on me for orde
