Yes if they start spinning in the material the corrective action could cause problems particularly when using something harder than a grade 5 bolt. The knurled ones are less likely to spin than the smooth sided ones, which I would not recommend for anything that will be disassembled and reassembled multiple times. The other key it to not over tighten the bolts going into them and of course not to cross thread said bolts.
