Click Type Torque Screwdriver

RNTD series

The Tohnichi RNTD series Click Type Torque Screwdriver The Tohnichi RNTD series is a high-precision, preset click-type torque screwdriver designed for high-volume assembly lines and maintenance where consistency is critical.Unlike adjustable screwdrivers with a visible scale, the RNTD series has its torque value locked internally, making it the primary choice for "error-proofing" (Pokayoke) in professional manufacturing.

Rotary-Slip (Cam-Over) Mechanism: When the target torque is reached, the tool "clicks" and then slips (ratchets freely). This means that even if the operator keeps turning the handle, no additional torque is applied, making it impossible to over-tighten.
Tamper-Proof (Preset): There is no external scale. To change the torque, you must use a specific adjusting key and a torque tester (like the Tohnichi TDT3-G). This ensures that only authorized personnel can change the tool's settings.
Extreme Durability: It uses Tohnichi’s proprietary toggle clutch mechanism, which reduces wear and maintains ±3% accuracy over a much longer lifespan than standard spring-click drivers.

The RNTD series is equipped with Tohnichi’s own toggle mechanism for torque control.

Mass Production Assembly: Ideal for workers on a production line who need to tighten thousands of small screws to the exact same torque without the risk of accidentally changing the setting.
Precision Electronics: Used extensively in assembling laptops, smartphones, and medical devices where even slight over-tightening could damage sensitive components.
High-Reliability Maintenance: Ensuring critical fasteners in automotive or aerospace sensors are tightened to strict specifications.

Specifications

Accuracy: ± 3% of the set value.
Mechanism: Rotary-slip (clutch ratchets freely once torque is reached to prevent over-torquing).
Bit Type: Accepts standard 1/4" (6.35mm) hex bits.
Standard Compliance: Meets ISO 6789 Type II Class E

◆ How to order The Tohnichi RNTD Series consists of preset, rotary-slip torque screwdrivers designed to prevent over-tightening. Because they are "preset" models, they have no external scale and require a torque tester. Specify Tohnichi, model name and torque value. Example 1: Tohnichi RNTD120CN X Torque Free Example 2: Tohnichi RNTD120CNX90cN・m
