Drywall screw gun
Features of a good screw gun
A good screw gun has following features:
Comfortability: A screw gun must be easy to hold onto. The thickness
and angle of their handles seemed just right. Especially the cushioned
rubber grips are really the favorites of the one using it
Noise: Screw guns running full blast can be very loud and irritating.
The new screw guns are all a lot quieter, and their noise levels are
quite tolerable.
Switches: Screw guns commonly are used in locked-on, full-speed mode,
so a lock-on switch's ease of use is an important issue. A good one lets
you relax your fingers.
Depth adjustment and bit replacement: The only thing required to be done
with a screw gun is to attach it to drywall. The depth adjustments on
most models are easy to use. Just slightly turn the end of the nosepiece
and it is all set.
Variable speed: If a screw gun is exclusively used for installing drywall,
you might think it doesn't need a variable-speed switch. It's cheaper
to manufacture a tool with a single-speed switch, but equipping a drywall
screw gun with variable speeds gives it a soft-start feature that can
increase the motor's life.
Belt clip: Some belt clips are removable. Remove their clips, and the
tools get within 1/2-inch of a corner like the rest of the screw guns
we tested.
Ways to use screw gun
A screw gun sets screws' bugle heads just below the drywall paper surface.
The tools' positive clutches engage when pressure is applied to the Phillips
bit and release when the pressure releases. You can adjust the screw
bit depth and how deep it sets screws. As a screw gun sets each screw
to the correct depth adjustment, the screw pulls the panel tight against
the framing as pressure from the nosepiece pushes against the drywall.
The screw head spins against the paper as it sinks, leaving a slight
dimple and a clean, smooth edge around the head. When the screw reaches
its proper depth, the clutch disengages. To use a screw gun properly,
hold the tool firmly as you drive each screw. That way, your hand and
forearm absorb most of the stress. Your wrist should almost align with
the nosepiece, and your thumb, index, and middle fingers ride along either
side of the motor housing. Pull the trigger and push the tool forward
with a punching motion. That engages the clutch, starts the screw rotating,
sinks it, and disengages the clutch in a fraction of a second. If you
don't maintain pressure on the tool after engaging the clutch, the screw
won't set properly.
