Overview
A round shank ends in a flat cabinet tip on this Klein terminal block screwdriver, which is made from alloy steel with a cushion grip handle. The recommended use is electric appliances.
The reason to buy is a narrow tip that fits small terminal screws and wire clamps. The limit is that one tip type covers only one fastener style.
Who it's for
Electricians and repair technicians working on terminals and small slotted screws. The cushion grip helps with careful turning. Occasional household use is better served by a multi-bit driver.
Pros and cons
- Cabinet tip for terminal screws
- Alloy steel build
- Single tip style
- Not for Phillips screws
- Short reach for deep recesses
Performance notes
A cabinet tip has parallel sides, so it seats in a slot without wedging out, which prevents damage to small terminal screws. A round shank gives clean access to screws in small openings. The cushion grip spreads hand pressure.
