• 1 set, a 115-piece screwdriver set.

Verified product specifications

• 150 mm analog caliper: Measuring the inner and outer dimensions and depth of a part using the sliding jaws. Analog sliding jaws are used to measure inner and outer dimensions and depth. The scale is calibrated for a 150 mm range.
• 115-piece screwdriver set: For removing and installing screws in small devices using various bits and accessories. Different bits are selected based on the appropriate screw head; the number of pieces in the set does not correspond to the number of separate screwdriver handles.

Reason for Use and Combination Therapy

When repairing small parts, removing a screw with the appropriate bit is a separate task. Tweezers hold the part in place, calipers compare dimensions, and a magnifying glass with a light allows you to examine the part’s position; none of these primary functions replace those of a screwdriver.

In this selection, the function of the main product is considered in conjunction with that of the complementary product. Users can use the products sequentially as part of their routine; the function of each component is listed below under its respective name. Components already included in a sales unit are not duplicated as separate products.

Care, Compatibility, and Usage Notes

The screwdriver tip is matched to the screw head, and the caliper jaw is positioned against the part to be measured. When reading the scale displayed by the caliper against the part’s actual dimensions, the position of the slide and jaws must be taken into account; the product is not presented as if it had a physical calibration certificate. Operations on the electronic device are performed in accordance with the device’s maintenance instructions. The magnifying glass stand does not include a soldering iron. The light or lens aids in viewing small details; it is not claimed to replace measurement or electrical safety checks.
