Adjust the tension of nuts or bolts.

Adjust the tension of nuts or bolts. is a detailed work activity in O*NET — a concrete unit of work shared across 4 occupations and seen in 4 occupation-specific tasks. It rolls up into the broader work activity Adjust equipment to ensure adequate performance. in Handling and Moving Objects .

Detailed work activities are the most granular shared layer in O*NET's work-activity hierarchy (Generalized → Intermediate → Detailed → occupation-specific task). The figures below describe how this activity shows up across the economy and what independent studies measure about AI and this kind of work — not a prediction that the work will be automated.

AI exposure

Of the 4 tasks under this activity that the OpenAI / Eloundou “GPTs are GPTs” study rated, 0 (0%) are flagged as directly exposed to language models (E1) or exposed via model-powered tools (E2).

Exposure estimates overlap with model capabilities — whether a model could speed the task up — not whether the work will be done by software. Observed AI use is augmentation and assistance today, not jobs replaced.

Member tasks

Occupation-specific tasks O*NET maps to this detailed work activity, most important first.

• Insert shims, adjust tension on nuts and bolts, or position parts, using hand tools and measuring instruments, to set specified clearances between moving and stationary parts. · Millwrights · importance 4.7 · no direct exposure
• Tighten loose bolts, using wrenches, and test circuits and connections by opening and closing gates. · Signal and Track Switch Repairers · importance 4.0 · no direct exposure
• Connect regulators to test stands, and turn screw adjustments until gauges indicate that inlet and outlet pressures meet specifications. · Control and Valve Installers and Repairers, Except Mechanical Door · importance 3.8 · no direct exposure
• Turn setscrews to adjust receivers for maximum sensitivity and transmitters for maximum output. · Radio, Cellular, and Tower Equipment Installers and Repairers · no direct exposure

Occupations that perform this
