Where This Product Fits

A tester screwdriver set is the technician's two-in-one: turn a screw, then touch the blade to a terminal and read the neon lamp before touching anything live. The four sizes in the JX-638 span the series' blade table, which makes the set a practical single-SKU addition for program buyers stocking electrical hand tools.
