I purchased a low torque precision torque wrench after stripping a stem bolt. The torque values are so low that stripping is always a danger. The torque values are too low for a Harbor Freight or similar torque wrench - around 5% of full scale --> the actual torque value in that range will around ±100% of the value, because the accuracy of the wrench is around ±5% of full scale (range).

Definitely would not ride a bike with stripped stem bolt, as noted above NOT safe.
