ProFix 100–600 Nm Micrometer Torque Wrench, 3/4 in Drive, ±3% Accuracy

What it is for

A torque wrench is a measuring instrument, and it drifts the way any instrument does: the spring inside takes a set if the tool is left wound up on the shelf, and the scale then reads low with nothing visible to warn you. What matters is not the range printed on the box but whether the wrench still holds its setting at the figure your manual quotes for a head bolt or a wheel nut.

This one covers 100–600 Nm on a 3/4 in drive at ±3% accuracy — the band you need for truck, bus and plant wheel nuts. Rewind it to its lowest setting between jobs rather than leaving it loaded and the calibration holds for years. That one habit is the difference between a wrench you can trust on a head bolt and one you cannot.

Specification detail

Range 100–600 Nm on a 3/4 in square drive, calibrated to ±3% of the indicated value. chrome vanadium steel body with a chrome plated finish, a knurled adjustment ring with a lock, and a sealed ratchet head. Supplied in a blow-moulded case; keep the wrench at its lowest setting for storage.

• Range 100–600 Nm held to ±3% — matched to the figures in the manual, not to the largest range on the shelf
• The adjustment ring locks in place, so the setting cannot creep while you work
• 3/4 in square drive takes the sockets and adaptors already in the workshop
• Rewind to the lowest setting between jobs — the spring then keeps its calibration for years
