Quick Introduction - Fine Adjustment Tutorial
Base Lab Tools offer a variety of fine adjustment screws and nut/bushings where interchangeability and cost of the assembly are key parameters. The thread class for these fine adjuster screws are typical 3A/3B the tightest thread class. Note that Base Lab Tools offer adjusters that are better than class 3A/3B that will have better performance and reduce the need for “sticky” grease to accommodate for the loose tolerance. These devices will have less backlash and longer life expectancy than standard 3A/3B adjusters.
