M4-0.7 x 30mm 六角頭螺絲 | 18/8 不鏽鋼 | 全螺紋 (500 顆/包)

These threads are clean and uniform, no burrs or weak spots along the whole 30mm length. I used them to rebuild a jig table and every single one seated perfectly with a socket. At 500 per pack, it's a solid value for shop stock.

The hex heads are precisely machined and grip my socket wrench perfectly, making assembly on my CNC table smooth. The 18/8 stainless steel feels solid and looks clean, no burrs or rough edges at all.

Got these for a repair project and the 18/8 stainless finish is exactly what I wanted to avoid any rust worries. The hex heads grip the socket perfectly and the 30mm length gave me plenty of thread to work with.
