Description
Snap-on builds two QC bodies around the same 5-75 ft-lb range. One is the preset QC2P75. The other is the Snap-on QC2I75 torque wrench body, which adjusts across the scale in 0.5 ft-lb steps. This page explains when the adjustable version is the better buy.
The Snap-on QC2I75 torque wrench body in numbers
| Range | 5-75 ft-lb (about 7-102 N·m) |
|---|---|
| Increments | 0.5 ft-lb |
| Shank | J (0.425 in) |
| Length | 13 in |
| Accuracy | ±4% clockwise, ±6% counterclockwise, 20-100% of full scale |
Read the accuracy line closely. On a 75 ft-lb body, 20% of full scale equals 15 ft-lb. So Snap-on’s stated accuracy applies from 15 to 75 ft-lb, while settings below 15 ft-lb fall outside it. For those small values, a lower-range body such as the QC1I200 is the safer pick.
Adjustable QC2I75 versus preset QC2P75
Snap-on’s catalog draws the line simply. Adjustable models give quick settings across the scale, while preset models stay dedicated to one torque value for repetitive assembly. In practice, the choice comes down to how often your target changes.
- Pick the QC2I75 for maintenance and repair, where specs change often.
- Pick the QC2P75 for a station that tightens one joint all shift.
- Also weigh paperwork, since Snap-on lists no certificate for preset bodies.
Fitting J heads to the QC2I75
This body takes J-shank heads, which measure 0.425 in at the shank. Snap-on offers them as square drive, open-end, box-end and flare nut heads. First, match the head to the fastener access. Then compare the head’s maximum working torque with your target, because some J heads stop below 75 ft-lb.
Head length matters
Most standard J heads put the fastener 2.50 in away from the retaining pin. Yet some specialty heads sit further out, so with those, follow Snap-on’s head-length instructions instead of a rule of thumb.
Typical QC2I75 jobs
- Brake caliper brackets and line fittings on light vehicles.
- Small pump and valve flange bolts.
- Hydraulic hose ends on farm machines, such as tractors and tillers.
- Cover and bracket bolts on gearboxes.

Is the QC2I75 accurate at 10 ft-lb?

Does the price include heads?
The listing does not say so. Ask Lost in HCM to quote heads as separate lines.
