💡 What torque range ensures longevity when installing metric m1.6 hex drive fasteners on sensitive control boards?

Low spin speed plus steady hand grip keeps these handy little drivers from camming out during rough shop work.

- Dial torque wrench below half a newton meter to protect stripped plating on thin enclosures. - Drop trace lubricant on mating threads to cut friction drag while sliding studs through alignment holes. - Inspect drive depth visually so recessed bits sit flush without poking insulation layers inside boxes.✝️
