The LBTEK high-precision M2.5 x 0.20 hex adjuster is operated by a 1.5 mm hex key driving the adjustment knob. One end of the adjuster features a hex socket, while the other end has a ball tip that serves as the contact point. To ensure smooth and stable adjustment, its maximum rated load is 4.5 kg.

The M3×0.25 precision hex adjuster allows for hand-tightening adjustment while also being compatible with a 2.0 mm hex wrench. The anti-slip knurled knob improves adjustment sensitivity.

The precision threaded bushings provided by LBTEK are typically used in clearance fit applications requiring fine adjustment. Considering the tolerances of these precision threaded bushings, press-fitting operations are not recommended. The recommended bore diameter for the M2.5 x 0.20 bushing is 4.00 mm (0~+0.02 mm). The recommended bore diameter for the M3 x 0.25 bushing is 4.50 mm (0~+0.02 mm). The recommended bore diameter for the M4 x 0.25 bushing is 5.50 mm (0~+0.02 mm). When screwing in the precision lead screw, it is recommended to insert it from the end without the step.
