Start a screw by hand whenever thread alignment is uncertain, the substrate is soft or the fastener is small. Two or more clean turns confirm engagement before the ratchet speeds the remaining travel; if the screw binds immediately, remove it and correct alignment instead of adding leverage.

It can loosen a screw that still has a sound recess and is within the tool and assembly limits, but leverage should come after inspection. Clean the head, confirm the exact bit, support the part and stop if corrosion, adhesive, damage or a safety-critical joint requires another removal method.

A ratchet driver is useful for repeated adjustment screws on a jig or fixture when the fastener interface, load and stop condition are known. It should not replace clamping hardware, calibrated torque or a machine-specific lockout procedure, and the fixture must be unloaded before adjustment unless designed otherwise.

It should not be used as a substitute for the printer maker’s hot-end, motion, electrical or calibrated assembly procedures, and frame alignment must be checked before any fastener is tightened.
Read article →A ratchet screwdriver is useful for compatible rack panels, cable-management parts and computer-case screws where clearance is limited. Rack mounting, power isolation, equipment weight and manufacturer torque requirements still control the job; use cage-nut, socket or calibrated tools when the hardware calls for them.
