Torque / Nm to ft-lbs / 500 Nm
500 Nm to Ft-Lbs
500 newton-meters equals 368.78 foot-pounds — heavy-truck wheel hardware and M20-class structural bolts. Convert it exactly; see where half a kilonewton-meter actually shows up.

Heavy truck wheel nuts
Class 6–8 truck and trailer wheels with M22x1.5 swivel-flange nuts are charted at 450–500 ft-lbs — note that figure is foot-pounds (~610–680 Nm), above this page's newton-meter value. In Nm terms, 500 Nm covers the upper range of 22 mm-stud dual-wheel hardware on lighter axles and hub-pilot wheels on mid-duty trucks.
M20 structural bolts
ISO 898 tables put M20 coarse at about 500 Nm for class 8.8 (10.9 charts at ~690 Nm) — 500 Nm is the textbook dry 8.8 M20 maximum, one of the few bolt sizes whose chart value lands on this page's number.
3/4-inch drive and torque multipliers
500 Nm is beyond routine 1/2-inch click-wrench comfort; truck shops use 3/4- or 1-inch drive, or a torque multiplier gearbox, because a long breaker bar plus a multiplier is safer than maxing out a wrench near its scale ceiling (accuracy degrades in the top 20% of range).
What is 500 Nm in foot-pounds?
500 newton-meters equals 368.78 foot-pounds (368.781074650 before truncation), using the NIST constant 0.7375621493. In inch-pounds the same torque is 4,425.37 in-lbs (foot-pounds × 12, converted before truncating).
Is 500 Nm a common torque setting?
Class 6–8 truck and trailer wheels with M22x1.5 swivel-flange nuts are charted at 450–500 ft-lbs — note that figure is foot-pounds (~610–680 Nm), above this page's newton-meter value. In Nm terms, 500 Nm covers the upper range of 22 mm-stud dual-wheel hardware on lighter axles and hub-pilot wheels on mid-duty trucks.
What about the reverse — 500 ft-lbs in Nm?
500 foot-pounds converts to 677.90 Nm (divide foot-pounds by 0.7375621493, or multiply by 1.355817948). Same number of units, very different torque — check which unit your spec sheet is actually written in before you set the wrench.
Where do these conversion numbers come from?
All conversions on this page are computed from the NIST value 1 Nm = 0.7375621493 ft-lbs, truncated (not rounded) to the displayed precision. Fastener and vehicle torque context is summarized from public bolt-torque charts (ISO 898 property-class tables) and manufacturer wheel specifications; always confirm critical values against your own service manual.
