I agree with Paul ....Grade 300 series S/S SHCS [Grub Screws] are as cheap as chips......
Remember the depth of the in-hex is ~~ 3/4 of the diameter...so don't fall into the trap of ordering M2 x2 SHCS.....the minimum in a perfect world is diameter ~~ x 2 for the length .....so M2 x 4 and M3 x 6
This provides greater mechanical cross section of material in shear so and in strength
Stainless steel in these Grades will not accept the Heat Treatment previously mentioned, so are more prone to over-tightening
They are available in Dog Point or Hollow Point......so shaft preparation is required to ensure the appropriate surface or indentation is provided to accept the intended HPGS or application...
M3 HPGS are also available in Brass
How could you not love the Metric system......an M2 brass nut can hold an M2 Grade 300 Series Hollow Coned HPGS which a can be held and tightened in an SW 3 Opended Spanner from Mr Krupfer .........all
So in addition to the mechanical securing and tightening of the HPGS via it's own in-hex, an additional Lock Nut can be added to the bolted connection
This then can eliminate the use of any Thread Locker type glue
