Automatically Slips Design. When the torque reaches the desired torque value, the cam mechanism automatically slips to prevent over-tightening. Materials Bit Holder: S45C Hexagon Knob: Anodic treatment Graduated Ring & Tube: Aluminum Grip: TPR Materials Bit Holder: Electroplating Hexagon Knob: Anodic treatment (Yellow) Graduated Ring & Tube: Anodic treatment (Black) Heat Treatment Bit Holder: HRB 90-94 Hexagon Knob: HRB 25-30 Step 1. Press the locking knob to adjust the torque. Step 2. Rotate the handle to adjust to the desired torque value. Step 3. Example desired torque value: 0.24 Nm Read the main scale with the sub scale. Step 4. Release the locking knob to lock. Spring-loaded locking collar locks the scale well when the torque value is set.

Precision Control When the torque reaches the desired torque value, the cam mechanism automatically slips to prevent over-tightening. 0.01 Nm increments give you the ability to be more precise with your torque settings as opposed to traditional torque screwdrivers that can only be accurately read to the nearest 0.1 Nm. Dual Scale for Conveniently Use Torque ranges from 0.1 to 1.2 Nm (1.33 to 10.18 in. lbs.) with dual scale. 0.01 Nm increments. ±6% Accuracy Read more Precision Certified Torque Limiting Screwdriver Set with Screwdriver Bits Precision Certified Torque Limiting Screwdriver Set with Screwdriver Bits Ultra Precision Certified Torque Limiting Screwdriver Set with Screwdriver Bits Ultra Precision Certified Torque Limiting Screwdriver Set with Screwdriver Bits Precision Certified Torque Limiting Screwdriver Set with Screwdriver Bits Precision Certified Torque Limiting Screwdriver Set with Screwdriver Bits Model Number H5178Y1 H51832Y1 H5177Y1 H51772Y1 H5187Y1 H5188Y1 Applications Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Torque Range 0.1-1.2 Nm / 1.33-10.18 In-lb 2-12 in-lbs 5-60 cNm (0.05-0.6 Nm) 0.5-6 in-lbs. 10-50 in-lbs 10-90 in-lbs Torque Increments 0.01 Nm 0.1 in-lbs 0.5 cNm 0.05 in-lbs 1 in-lbs 2 in-lbs Torque Accuracy ±6% Accuracy ±6% Accuracy ±6% Accuracy ±6% Accuracy ±6% Accuracy ±6% Accuracy T Handle ✓ ✓ Bits & Extension Bar ✓ ✓ ✓ ✓ ✓ Quick Release Design ✓ ✓ ✓ ✓ ✓ ✓ Head Size 1/4 Inch 1/4 Inch 1/4 Inch 1/4 Inch 1/4 Inch 1/4 Inch Precision Certified Torque Limiting Screwdriver 0.1-1.2 Nm / 1.33-10.18 In-lb Precision Certified Torque Limiting Screwdriver 2-12 in-lbs Precision Certified Torque Limiting Screwdriver 5-25 in-lbs Precision Certified Torque Limiting Screwdriver 10-50 in-lbs Precision Certified Torque Limiting Screwdriver 10-90 in-lbs Precision Certified Torque Limited Screwdriver 5 to 10 Nm/48.68 to 84.08 in-lbs Model Number H5178 H51832 H51835 H5187 H5188 H5184 Applications Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Electrical, Automotive, Aerospace, Manufacturing Torque Range 0.1-1.2 Nm / 1.33-10.18 In-lb 2-12 in-lbs 5-25 in-lbs 10-50 in-lbs 10-90 in-lbs 5-10 Nm / 48.68-84.08 in-lbs Torque Increments 0.01 Nm 0.1 in-lbs 0.5 in-lbs 1 in-lbs 2 in-lbs 0.1 Nm Torque Accuracy ±6% Accuracy ±6% Accuracy ±6% Accuracy ±6% Accuracy ±6% Accuracy ±6% Accuracy T Handle ✓ ✓ ✓ ✓ Bits & Extension Bar Quick Release Design ✓ ✓ ✓ ✓ ✓ ✓ Head Size 1/4 Inch 1/4 Inch 1/4 Inch 1/4 Inch 1/4 Inch 1/4 Inch
