USE/CARE OF HANDTOOLS & MEASURING TOOLS - OD1621 - LESSON 2/TASK 1
FIGURE 13.
HOLDING SCREWDRIVER PROPERLY.
(2) Removing Tight Screws.
When a screw cannot be turned at the
first attempt to remove it, try to tighten it first, then turn the
screwdriver in the opposite direction. Sequentially, tighten and loosen the
screw until completely removed.
CAUTION
Use a screwdriver that has parallel sides and exactly
fits the screw slot.
A poorly fitting screwdriver
will damage the screw head, slip off the screw, and
perhaps cause personal injury.
If a tight screw with a damaged slot can be backed out partially, it is
possible to remove it completely with a pair of pliers.
