These are the small screws with countersunk heads used to secure the hinges and circular guides on LPL negative carriers as supplied for LPL, Saunders/LPL, Jobo/LPL, and Omega/LPL 4x5 enlargers. The package of 10 screws is enough to replace all the screws in one carrier.
Note: These screws fit the 4x5 series negative carriers only.
