These are genuine Shimano inner gear fixing bolts (part Y1MJ98010) for the Tiagra FC-4603 triple road crankset. The pack holds five sets, enough to fix the inner (small) chainring all the way round.
Inner ring bolts are a different length to the ones that hold the outer and middle rings together, so it pays to use the right part. At M8 x 9.6 mm, these match Shimano's spec for the FC-4603 inner ring.
