M6 x 6mm Grub Screws 50 Pack

These Unique-Bargains grub screws supply a black 12.9 alloy steel fastener with M6 thread and 1mm pitch. The hex socket cup point design suits applications such as locking pulleys or gears to shafts. A pack of 50 pieces covers multiple assembly points for mechanics and hobbyists.

Capacity and headroom

Fifty screws weighing 40g provide enough hardware for several wheel or machine assemblies. The 6mm length and cup point limit use to shallow thread engagement, so they will not suit deeper holes or high-shear structural joints requiring longer bolts.

1mm pitch thread specification

The 1mm pitch defines compatibility; only M6 tapped holes cut to this pitch will accept these screws. Buyers with coarse-thread M6 holes or imperial threads cannot use this pack.

  • Precise M6 x 6mm threads at 1mm pitch for secure fit
  • Cup point design grips shafts without marring surfaces

Questions about this item

Will these M6 x 6 mm grub screws thread into an existing 1 mm pitch tapped hole?

Yes, the 1 mm pitch matches standard M6 coarse threads, so they will engage correctly in a compatible tapped hole.

How can I confirm the 12.9 alloy steel screws are seated properly after installation?

Tighten each screw with a 3 mm hex key until the cup point contacts the shaft firmly; the black oxide finish makes full engagement easy to see.

Does the pack contain exactly 50 black M6 x 6 mm screws and nothing else?

The box includes 50 pieces of the grub screws; no hex key or additional hardware is supplied.
