The tolerance for a 6.35 H7 hole is defined by the H7 system, which specifies a certain range of limits for the hole's diameter. For a 6.35 mm nominal size, the H7 tolerance range typically allows for a hole diameter of 6.35 mm +0.025 mm to +0.000 mm, meaning the diameter can range from 6.35 mm to 6.375 mm. This tolerance ensures a precise fit, suitable for applications requiring a specific clearance or interference fit with corresponding shafts.
The tolerance for a 150mm H7 hole is typically specified as +0.000 mm to +0.075 mm. This means that the hole's diameter can range from 150.000 mm to 150.075 mm, allowing for a precise fit while accommodating certain manufacturing variances. The "H7" designation indicates a specific level of fit, ensuring that the hole is neither too tight nor too loose for mating parts.

Slip gauges (also known as gage blocks, Johansson gauges, or Gauge blocks) are precision ground and lapped measuring standards. They are used as references for the setting of measuring equipment such as micrometers, gap gauges, sine bars, dial indicators (when used in an inspection role). They are available in various grades depending on their intended use. · Calibration (AA) - (tolerance +0.00010 mm to -0.00005 mm) · Reference (AAA) -high tolerance (± 0.00005 mm or 0.000002 in) inspection (A) - (tolerance +0.00015 mm to -0.00005 mm) · workshop (B) - low tolerance (tolerance +0.00025 mm to -0.00015mm

The ideal mechanical advantage (IMA) of a screwdriver is calculated by dividing the shaft radius by the handle radius. In this case, the IMA would be 4 mm (shaft radius) divided by 12 mm (handle radius), resulting in an IMA of 1/3 or approximately 0.33.
Mine is 5 mm
