Spanners, Pliers & Screwdrivers (Junior Cert Engineering): Flashcards

Tighten, loosen, grip, and turn fasteners and components

$15^circ$ angle to the handle

Can flip over to work in confined spaces at different angles

Completely encircle nut/bolt, eliminating risk of slipping

Deep recesses where standard spanners cannot reach

Using a tommy bar through holes in the spanner body

Modularity - various sizes, handles, extensions, and joints

Higher risk of slipping compared to fixed-size spanners

Pipes and other cylindrical objects

Serrated jaws damage the corners, making removal difficult

Can cut wire

Round objects such as pipes and bars

Can lock onto workpiece and maintain grip without hand force

Slotted screws (single straight slot across head)

Better grip and torque transmission, less likely to slip
