VIGRUE 300Pcs M2.5/M3/M4/M5/M6/M8 Hex Allen Head Socket Set Screw Bolts Assortment Kit Grub Screw with Internal Hex Drive, 304 Stainless Steel (Metric)

This is a great set screw kit. It comes with the hex wrenches and many sizes of set screws. These are flat tipped, not cone-tipped so make sure you get the right ones! Great description, great speed of delivery, solid kit, great price! Highly recommend.

I needed a replacement for one size m4 set screw. This entire 300 piece kit was such a bargain, I couldn’t resist. Now if only I can find a use for the remaining 299 screws.

The socket screws are cup type and seem to be fine. The hex keys are usable (if you do not use much torque) but of poor quality.

My 4 channel amp had those dreaded Phillip head set screws so I swapped em out with these. These are a bit longer. And I was able to swap out every set screw in the amp with these Allen ones. The way it should have been to begin with lol.

Like the variety, need to add different lengths,smaller inserts.Needed it for a hanging dremmel tool.
