Self -tapping
After which the frame profile is attached to them with self -tapping screws.
In the ceiling, which
Assembling the frame and its fastening to the base is carried out using screws and dowels with a step 30-40 cm.
Speed ranges-for
Among other functional capabilities of screwdrivers, attention should be paid to the following:
Power source
The listed shortcomings are overcome in lithium-ion batteries, but they are more expensive at the price.
To charge them for
In addition, nickel-cadmium batteries are prone to self-discharge and it does not make sense to charge them for the future-the charge will not remain.
Battery capacity will
- However, if you begin to charge such a battery after incomplete discharge, zones that do not form an electric charge form in it.
Are durable, capable of
- Bquighties in screwdrivers use nickel-cadmium and, more modern, lithium-ionic.
To avoid thread breakdown
- The torque regulator makes it possible to experimentally choose the necessary value for specific working conditions to avoid thread breakdown, damage to the slots or premature discharge of the battery.
