Williams 5T-IW Single Setting Torque Wrench, J-Shank (10-50 in-lb)

Description

The Williams 5T-IW is a universal round-shank single-setting torque wrench with a J-shank (0.425″ arbor) that accepts Williams’ interchangeable open-end, box-end, and flare-nut heads. It’s set once to a target torque and gives an audible click plus a tactile impulse when that torque is reached — a fast, repeatable go/no-go signal for production environments where a fastener is torqued the same way, over and over. Tamper-proof housing and cushion grip; range 10-50 in-lb (1.1-5.6 Nm).

Accuracy is ±3% CW of indicated value from 20-100% of full scale, meeting or exceeding ASME B107.300. This is the unset (operator-adjustable) version. Williams also offers this same wrench factory pre-set to a specific torque with its own certificate of calibration (model 5T-I-SETW) for production lines that don’t want the setting to be adjustable on the floor.

This design is well suited to production-line assembly and MRO work where the same fastener gets torqued repeatedly and a fast, unambiguous click matters more than a dial or digital readout.

**Frequently asked questions**

**How often does this need to be recalibrated?** Williams recommends annual recalibration for tools in regular use, or sooner if the tool is dropped, used outside its rated range, or run at high frequency in production. Keep the original NIST-traceable calibration certificate on file for your quality records.

**What standards does it meet?** Meets or exceeds ASME B107.300 (the current consolidated standard for hand torque tools, superseding the older B107.14) and ISO 6789. Each unit is individually serialized and ships with its own certificate of calibration.

**Can it be used in both directions?** Check the accuracy spec above — some models are calibrated clockwise (CW) only, others bidirectionally (CW/CCW). Using a CW-only tool for critical CCW work will not give a certified reading.
