TEKTON Torque Wrench Review: Which Model to Buy

Is TEKTON a good torque wrench brand?

For most home and many professional users, yes. The current micrometer wrenches are rated ±3% in both directions and calibrated to ISO 6789-1:2017, which TEKTON says also meets or exceeds ASME B107.300-2021, and each one ships with a serialized certificate that records its test results. That is a tighter rating on paper than many better-known click wrenches, several of which are rated only from 20% of the scale upward.

TEKTON's torque wrenches are made in Taiwan. Its warranty has no time limit and needs no receipt, and it offers a paid recertification service for its current models, so a TEKTON wrench can be checked and adjusted rather than replaced when it drifts.

Which TEKTON torque wrench should you buy?

Match the drive and range to the fasteners you tighten most:

• Engine-bay and general work: the 3/8-inch TRQ51402, 10–100 ft-lb.
• Wheels, suspension and chassis: the 1/2-inch TRQ52402, 40–200 ft-lb, or the TRQ52403, 40–300 ft-lb, for trucks.
• Small fasteners: the 1/4-inch TRQ50402, 20–200 in-lb.
• Torque-plus-angle procedures: the electronic TRQ81122, or the 1/2-inch TRQ82123 (30–300 ft-lb).
• Frequent setting changes without winding down: TEKTON's new split-beam line, the 3/8-inch TRQ61122 and 1/2-inch TRQ62122, sold together as the TRQ96901 set.

Old TEKTON vs new TEKTON

TEKTON's earlier micrometer wrenches, such as the 24335 and 24340, were rated ±4%, calibrated to the 2010 edition of ASME B107.300 and tested at 20%, 60% and 100% of the scale. They drove in both directions but measured torque only clockwise, and TEKTON says they did not include a certificate. Both are listed as no longer available.

The current TRQ line, released in 2025, is rated ±3% in both directions, calibrated to ISO 6789-1:2017 (which TEKTON says also meets or exceeds ASME B107.300-2021), tested from the lowest marked value upward, and certified individually. If you already own an older TEKTON that checks out well, keep using it; if you are buying, get the current model. TEKTON renewed its split-beam wrenches in 2026 too: it lists the older TRQ62103 as a version without a certificate and the TRQ62203 as no longer available.

Click, split-beam or electronic?

A micrometer click wrench is the simplest choice: set the value on the handle and pull until it clicks. TEKTON's split-beam wrench also clicks, but it has no preloaded spring, so it can be stored at any setting; the trade-off is a ±4% clockwise-only rating. The electronic wrench reads the torque live, alerts you as you approach the target and adds an angle mode. Our beam vs click vs digital guide explains each type in more depth.

What ±3% means in practice

On TEKTON's current micrometer wrenches, ±3% is the worst case allowed anywhere on the scale, in either direction; the certificate shows what your own wrench measured. At a 60 ft-lb setting, ±3% allows 58.2 to 61.8 ft-lb.

Many click wrenches are rated only from 20% of their scale upward, which leaves the bottom fifth unrated. TEKTON tests at the lowest marked value, so a 10–100 ft-lb TRQ51402 is rated at 10 ft-lb as well, which helps with low engine-bay values.

Looking after a TEKTON torque wrench

Store the micrometer wrenches at their lowest marked setting, as TEKTON's manual says, and set that lowest value before you switch the ratchet direction. Never use a torque wrench to break a fastener loose.

Check it at least once a year or every 5,000 cycles, the ISO 6789 benchmark, and straight away after a drop. Our calibration guide shows how to check a wrench at home, and TEKTON's recertification service can adjust it if it is out.
