LX-TW14
LX-TW14 is a 1/4-inch drive torque wrench with a 30-250 in-lb (3.4-28.2 Nm) scale for compatible small fasteners. Its 13.5-inch body, rubberized rotating grip and twisting setting collar accompany a 24-tooth, dual-direction ratchet; specifications below 30 in-lb require another tool.
LX-TW14 pairs a quarter-inch drive with 30-250 in-lb or 3.4-28.2 Nm for compatible small fasteners. It measures clockwise and counterclockwise.

Combine the main reading with 1 in-lb micrometer steps. Twist the collar left to unlock and right to lock; the ratchet has 24 teeth.

LX-TW14 includes the wrench, hard storage case, manual and calibration certificate. A bicycle bit assortment is not included in this package.

Match the required torque, measurement direction, square drive and working space to the equipment specification.
| Job or attachment | Works | What to check |
|---|---|---|
| Small fasteners requiring 30-250 in-lb | Yes, when specification fits | Clockwise and counterclockwise tightening within 30-250 in-lb; follow the equipment maker's torque value. |
| 1/4-inch drive sockets | Yes | Match the socket opening to the fastener and allow space for the wrench. |
| 3/8-inch drive sockets | No direct fit | Match the square drive rather than the socket opening size. |
| Fasteners below 30 in-lb | No | Use a lower-range torque tool. |
| Fasteners above 250 in-lb | No | Use a higher-range torque tool. |
| Left-hand threaded fasteners | Yes, within range | Counterclockwise accuracy claim is +/-6%. |
| Stuck fasteners and added leverage | No | Do not use as a breaker bar or add leverage devices. |
LX-TW14 provides a 1/4-inch square drive and 30-250 in-lb scale. It can suit a bicycle fastener only when its specified torque, thread direction and attachment fit that interval. Read the component instructions; no universal bicycle tightening value is supplied.
Check whether the panel's specified value falls within 30-250 in-lb and use an appropriate 1/4-inch drive attachment. Confirm insulation and live-work requirements before choosing LX-TW14 for electrical work.
The LX-TW14 minimum is 30 in-lb. A 20 in-lb specification requires another instrument whose rated range includes it. Matching a small socket to this quarter-inch drive does not make readings below 30 in-lb valid.
25 Nm is inside LX-TW14's 3.4-28.2 Nm interval. Confirm that the component specifies Nm, select the proper attachment and follow the marked-scale setting procedure; the numeric fit alone does not establish access or fastener compatibility.
LX-TW14 measures torque in both tightening directions. Its claimed accuracy is +/-6% counterclockwise and +/-4% clockwise. Identify the thread direction from the component instructions and stay within 30-250 in-lb in either direction.
LX-TW14 is 13.5 inches (34.3 cm) long. Allow room to position and pull the handle as instructed; a small drive does not make the whole wrench short.
No. LX-TW14's primary scale is 30-250 inch-pounds, paired with 3.4-28.2 Nm. Foot-pound settings belong to other models. Check the complete unit on your service specification before turning this handle.
The micrometer increment for LX-TW14 is 1 in-lb. Its main scale advances in 20 in-lb steps, so the main and micrometer values must be added; one small adjustment is not another 20 in-lb step.
One LX-TW14 Nm micrometer division is approximately 0.113 Nm, equivalent to 1 in-lb. Use the matching scale and combine the main and micrometer readings for the required setting.
250 in-lb is the upper endpoint for LX-TW14, not permission to keep pulling. Release at the first torque impulse. Additional force after the signal can exceed the chosen torque even when the handle setting remains locked.
LX-TW14 has 24 ratchet teeth. The quarter-inch drive and quick-release socket button do not imply a 72-tooth mechanism. Check the head and available working clearance for your job.
Do not use LX-TW14 to break free stuck fasteners or add leverage devices. Use suitable removal equipment for that step and reserve this 30-250 in-lb measuring wrench for the tightening procedure.
Both have a 1/4-inch drive and measure both directions. LX-TW14 covers 30-250 in-lb with a 24-tooth head and 13.5-inch length; LX-180 covers 10-150 in-lb with 72 teeth and an 8.7-inch length. Choose the low limit, high limit and access your job requires.
LX-TW14 has a hardened, heat-treated chrome-molybdenum internal mechanism. That alloy claim applies to the mechanism; the rotating grip is rubberized.
LX-TW14 has a rubberized rotating grip and a separate lock/unlock collar. The grip helps you turn and hold the handle; retaining the selected reading requires locking the collar.
LX-TW14 includes the wrench, hard storage case, manual and calibration certificate. Obtain the bit needed for your fastener separately; this package does not include LX-191's bicycle bit assortment.
LX-TW14's certificate records calibration at assembly, without an expiration date. Expected accuracy is 5,000 clicks, about two years from first use, with low-setting storage in an appropriate environment. Your shop's validity rules may be stricter, so confirm them before ordering.
Lifetime coverage when you register online within 90 days of purchase; 12 months standard without registration. Commercial use is limited to 12 months without extension, industrial use is excluded, and the policy covers defects in material and workmanship.
For LX-TW14, twist the lock/unlock collar left, rotate the handle to combine the main in-lb and micrometer readings, then twist the collar right to lock. Recheck the value and use hand force; the collar is not a sliding latch.
If the LX-TW14 adjustment detent does not align with the marked scale, do not force a guessed setting or change internal parts. Follow the collar procedure and ask Lexivon to assess persistent alignment trouble before using it on a critical fastener.
LX-TW14 low-torque feedback can be subtle. Practise recognizing the felt impulse with a slow pull on a non-critical fastener. If you cannot reliably detect the signal, stop rather than tightening farther solely to hear it.
Leave LX-TW14 at 30 in-lb with the micrometer zero aligned for storage. Never adjust below that minimum. The case protects the stored instrument, but it does not replace reducing the setting to the correct low mark.
Wipe LX-TW14 with a dry, lint-free cloth and avoid immersing the instrument or using liquid cleaner. Following prolonged storage, perform several operations at low torque before normal work; a clean grip alone does not check the internal mechanism.
If LX-TW14 is missing from the online list, contact Lexivon for manual registration assistance within 90 days of purchase. Registration extends defect coverage, not calibration service. Routine recalibration, wear, misuse, modifications and non-original parts remain excluded.
