The 076459 Mountz FG-20i CR-HVG Preset Cleanroom Torque Screwdriver (w/ High Vacuum Grease) is engineered for ultra-high vacuum (UHV) and optics applications, featuring high-vacuum grease (HVG) with exceptionally low vapor pressure to prevent airborne contamination while maintaining lubrication performance. Its low-outgassing powder coat finish eliminates flaking paint, ensuring a clean, particle-free environment. Designed for sensitive assembly processes, this tool incorporates dynamic wear-resistant seals that provide a double barrier against grease leakage, ensuring cleanroom compliance.

The 076459 Mountz FG-20i CR-HVG Preset Cleanroom Torque Screwdriver (w/ High Vacuum Grease) is pre-set to a fixed torque value, delivering consistent fastening precision for repetitive, high-accuracy applications. Its cam-over poka-yoke mechanism eliminates over-torque risks, preventing fastener damage and ensuring compliance with ISO 6789 standards (+/- 6%). The tamper-proof internal adjustment system guarantees that the correct torque is always applied. Adjustments can be made internally using a hex key and torque tester for flexibility in changing torque specifications.

This cleanroom-rated screwdriver is built to withstand frequent cleaning with water and isopropyl alcohol-based solvents, making it ideal for stringent contamination control environments. The ergonomic handle design reduces hand fatigue, improving operator comfort during high-volume assembly tasks. Additionally, the secure bit-locking mechanism with one-touch release minimizes bit wear, enhancing efficiency and reducing downtime.

Backed by an industry-leading 2-year unconditional warranty and a lifetime guarantee against defects, the 076459 Mountz FG-20i CR-HVG Preset Cleanroom Torque Screwdriver (w/ High Vacuum Grease) delivers precision, durability, and cleanroom compliance. Available in clockwise (CW) or counterclockwise (CCW) configurations, ensuring adaptability for various applications.
