M8 X 18mm براغي تثبيت بمقبس سداسي بنقطة كوب | فولاذ سبائكي (250 قطعة/عبوة)

The hex socket drive made cinching these down in a tight motor mount a breeze, even with limited swing room. Cup point bites into the shaft firmly and the whole pack of 250 feels uniformly machined. Worked perfectly for my project.

These are perfect for securing pulleys on a shaft where you need a strong bite without marring the surface too much. The cup point grips firmly, and the hex drive lets me get them torqued down in a tight spot. All 250 were in the box and the threads looked clean.

The hex socket drive made tightening these in my motor pulley a breeze with my Allen key. For 250 pieces, the alloy steel feels robust and the cup point grips the shaft firmly.
