Do not underestimate that HF torque wrench. Several years ago, I found an auto-engineering website that checked the calibration of a newly-calibrated Snap-On torque-wrench against a newly bought HF torque wrench. The HF wrench was as close to the correct torque (over a range of torques) as was the Snap-On wrench.
I did own test comparison with a friend's newly calibrated torque wrench compared to my never calibrated (but, rarely used) HF torque wrench. My wrench was +/- within 5% of the Snap-On wrench (over a range torque settings.
I tighten to the specs, if I have them.
