*KeyFeatures *High Compatibility & Laser Calibration: Our calibrated torque screwdriver offers a torque range of 10-70 in-lbs with 1 in-lbs torque increments, making it suitable for a wide range of screw sizes and enabling precise tightening or loosening of screws. The laser-engraved scale allows for easy reading and operation even in low-light environments. *Lightweight & High Strength: Constructed with a high-quality aluminum alloy body and featuring a durable alloy steel blade, our torque screwdriver is lightweight for reduced fatigue during use. The alloy steel material ensures excellent wear resistance, corrosion resistance, and prevents deformation or damage, making it suitable for use in high-temperature environments. *Over-Torque Reminder: As you approach the preset torque, the torque screwdriver produces an audible "click" sound and automatically slips, preventing under-tightening or damage caused by over-tightening. *Quick Setup: Setting the desired torque value is quick and easy, even for beginners. Simply rotate the adjustment wheel and press down in two simple steps, then turn the handle to achieve the desired torque value. *Product Includes: 1x Portable Tool Box, 1x Extension Bar, 1x T-handle, and 12x Bits (3x Phillips: #0, #1, #2; 3x Flathead: 3/16, 1/4, 3/8; 3x Hex: 5/64, 3/32, 5/32; 3x Torx: T10, T15, T21). ******************************************************************************************************* *Specifications Item Model Number: RTD-10-70 Type: Scale Range: 10-70 in-lbs / 1.13-7.91 N.m Torque Increment: 1 in-lbs Bit Size: 1/4" Net Weight: 1.65 lbs / 0.75 kg Product Size: φ 1.63" x 7.56" / φ 41.5 x 192 mm ******************************************************************************************************* *Pakcage Content 1 x Tool Box 1 x T-shape Handle 1 x Extended Handle 3 x Flathead Bit (90-6、 38-4、 CR-V3) 3 x Cross Bit (S2-PH0、 S2-PH1、S2-PH2) 3 x Hexagon Bit ( 5/64、 3/32、5/32)
