The Best Split-Beam Torque Wrenches

Setup & use · per the maker

• 20–100 ft-lb in 2 ft-lb steps, with a flex ratchet head. 17-5/64 in overall, an effective length of 14-31/64 in, and 1.48 lb without its case.
• Pull back the lock lever to free the set knob, turn the knob up to the value shown at the set mark, then release. It clicks as the wrench releases at the setting. Precision Instruments says setting it takes only fingertip force, because the adjustment mechanism isn't under load.
• Rated ±4% from 20% of full scale to full scale, so from 20 ft-lb up, and clockwise only. Precision Instruments says every wrench other than the C series works in both directions.
• Because the C series uses no coil spring, the maker says there's no need to work it in when new or to wind it down to the lowest setting after use: it can be stored at any value.
• Meets or exceeds GGG-W-686C and ANSI B107.14M. A storage case is included, and the maker offers a calibration certificate as a $20 option; the marketing copy carried by retailers describes a dated calibration compliance certificate in the box, which is not the same as a record of readings.
• The maker says every wrench should be calibrated at least every six months, and its one-year warranty is void if the wrench isn't calibrated periodically. Don't use it to break fasteners loose.

What others found

• Two owners, in Garage Journal threads thirteen years apart (2011 and 2024), give the same reason for buying one: a split-beam can't be left wound up, so it doesn't lose its calibration when somebody forgets to wind it down.

• Split-beams still drift. In a 2023 BobIsTheOilGuy thread, one owner had two near-new Precision Instruments wrenches tested and found both reading high before adjustment, including a 3/8-inch 5.4% high at 120 in-lb; another in the same thread found his 3/8-inch out of spec after a year or two of working it near its capacity.

  BobIsTheOilGuy: split-beam torque wrench calibration

Grassroots Motorsports checked a Precision Instruments split-beam on a torque tester and called it the least accurate but the most consistent in that comparison. It doesn't give the model number, and the wrench was borrowed from a mechanic who said it was high-mileage and overdue for a tune-up, so we treat it as background rather than a verdict on a new one.

• 40–250 ft-lb in 5 ft-lb steps, with a flex ratchet head. 22-1/8 in overall, a 19 in effective length, and 3.39 lb without its case.
• Pull back the lock lever to free the set knob, turn the knob up to the value shown at the set mark, then release. It clicks as the wrench releases at the setting. Precision Instruments says setting it takes only fingertip force, because the adjustment mechanism isn't under load.
• Rated ±4% from 20% of full scale to full scale, so from 50 ft-lb up, and clockwise only.
• The C series uses no coil spring, so the maker says there's no need to work it in when new or to wind it down after use: it can be stored at any value.
• Meets or exceeds GGG-W-686C and ANSI B107.14M. A storage case is included, and the maker offers a calibration certificate as a $20 option; the marketing copy carried by retailers describes a dated calibration compliance certificate in the box, which is not the same as a record of readings.
• The maker says every wrench should be calibrated at least every six months, and its one-year warranty is void if the wrench isn't calibrated periodically. A ratchet service kit is sold separately. Don't use it to break fasteners loose.

What others found

• In a 2023 BobIsTheOilGuy thread, one owner had a near-new 1/2-inch Precision Instruments split-beam tested and found it 12% high at 50 ft-lb, the bottom of that wrench's own scale, and within 1% after adjustment; another in the same thread found his 3/8-inch out of spec after a year or two of working it near its capacity.

• TRQ61122: 3/8-inch drive, 20–100 ft-lb in 2 ft-lb steps, tested at 20, 60 and 100 ft-lb. 18.8 in long, an effective length of 15.6 in, 2.1 lb.
• TRQ62122: 1/2-inch drive, 50–250 ft-lb in 5 ft-lb steps, tested at 50, 150 and 250 ft-lb. 22.8 in long, an effective length of 19.2 in, 3.8 lb.
• Both are rated ±4% clockwise, to ISO 6789-1:2017 and ASME B107.300-2021, and calibrated across the full range rather than from 20% of scale. Each comes with a serialized certificate listing its own results.
• Both have a 90-tooth head with a 4° swing arc and a 10° flex. Each wrench's own product page lists a case, a serialized certificate and a drive reducer with it: 3/8-to-1/4-inch on the smaller wrench, 1/2-to-3/8-inch on the larger. The set page itself doesn't itemise them.
• TEKTON's split-beam manual says the wrench can be stored at any torque setting because there's no internal tension when it's at rest, so there's no winding down to do.
• Don't use them to break fasteners loose or add an extension to the handle, and verify accuracy after a drop. Both are covered by TEKTON's no-time-limit warranty and are on the list for its paid recertification service. Made in Taiwan.

What others found

This is TEKTON's new 90-tooth split-beam line and we found no owner reviews or independent test of it. Forum discussion you may find of TEKTON split-beams is about the older 72-tooth wrenches.

• 50–250 ft-lb in 5 ft-lb steps, set with a knob against a scale window. 23.23 in long, 3.8 lb, made in Taiwan per Capri.
• Capri rates it ±4% clockwise across the entire torque range, rather than from 20% of scale. On a 50–250 ft-lb wrench those come to the same usable window in practice.
• 72-tooth ratchet with a 4° swing arc and a ±10° flex head. The Amazon bullet's "±10%" is a typo that several retailers have copied.
• Capri says a split beam doesn't require setting the torque back to zero to keep its accuracy between uses, so your usual setting can stay on the wrench.
• A custom fitted case and a certificate of conformance with a traceable serial number are included; Capri's own page calls it a "calibration certificate of conformance". A certificate of conformance states that the wrench meets the spec, rather than recording what your particular wrench measured.
• Capri's product page gives a one-year warranty, and its general guidance is to recalibrate about once a year or every 5,000 load cycles. We found no manual for this wrench, so there's no maker guidance on breaking fasteners loose or on adapters.

What others found

Owner feedback on this model is almost non-existent: Walmart and Lowe's show no reviews, we found no readable review text anywhere else, and the eBay comments we found are seller feedback rather than product reviews. We found no independent test of it. Capri cites ISO 6789:2003 and ASME B107.300-2010 in a general article, both superseded editions.

• 120–600 in-lb in 10 in-lb steps, which is 10–50 ft-lb. Flex-head ratchet, 17-1/8 in long, per CDI's catalog.
• Rated ±4% of any clockwise setting from 20% of full scale to full scale, so from 120 in-lb up — which is this wrench's marked minimum anyway.
• CDI's catalog says it's designed for measuring torque clockwise only and that the wrench is not reversible.
• Set with a thumb screw, with a guard against changing the setting by accident, and a sealed ratchet head and neck to keep grit out of the mechanism.
• CDI's catalog describes the split-beam measuring element as giving accurate, reliable readings while eliminating the heavy coil spring. It doesn't say in as many words whether this one can be left set, and CDI's general guidance, written for its micrometer wrenches, says to store a torque wrench at its lowest setting.
• CDI recommends recalibration once a year or every 5,000 cycles, whichever comes first. Never break fasteners loose with it and never use a cheater bar. CDI says it cannot warrant the calibration of any tool.

What others found

We found no owner reviews of this model and no independent test of it. Zoro now lists it as discontinued, so check it's still sold before ordering.

Setup & use · per the maker

• 200–600 ft-lb in 10 ft-lb steps. 48-29/64 in overall with an effective length of 44-31/32 in, which is the figure to use for any extension arithmetic. 11.76 lb bare, 14.18 lb in its case.
• Rated within 4% from 20% of full scale to full scale, which on a wrench that starts at 200 ft-lb covers its whole marked range. The maker's site words this as 4% of reading and its manual as 4% of the setting, and its catalog labels the figure clockwise.
• For counter-clockwise work the manual has you push the lock button in and rotate the ratchet head until the button locks in the opposite hole, with the reversing lever to the right. The maker gives no accuracy figure for that direction.
• The manual adds an orientation caveat: the wrench is calibrated in a neutral position, where its own weight neither adds to nor subtracts from the torque, and in any other orientation the accuracy is within 5% of full scale rather than 4% of the setting.
• Precision Instruments says setting it takes only fingertip force, because the adjustment mechanism isn't under load, and that the C series has no coil spring, so there's no need to wind it down after use.
• Meets or exceeds GGG-W-686C and ANSI B107.14M, and is made in the USA. The tool breaks down into ratchet, torque body and extension tube, and a ratchet repair kit is sold separately.
• The maker says every wrench should be calibrated at least every six months, and the warranty on its site runs one year and is void without periodic calibration, though the manual supplied with this wrench states 90 days. Don't use it to break tight fasteners loose.

What others found

This is a specialist wrench at a specialist price, and it has essentially no public owner feedback: the maker's own page and the retailers we could read show no reviews. We found no independent test of it.
