Considerations & Trade-offs

  • Sold in a 12-pack, so it’s geared toward keeping spares on hand rather than buying a single replacement screw.
  • Length is listed as nominal shank length, so fit should be confirmed against your specific rings or bases before ordering.
  • These are intended for scope mounting applications and may fit many brands, but compatibility is not universal.
  • Stainless steel with a bright finish may not match every existing screw kit or mount finish exactly.
