Stubby Nut Driver 5/16 Inch
The Klein Tools 610-5/16 is a stubby nut driver built for SAE fasteners measuring 5/16 inch. Its short shank length of 1 1/2 inches suits technicians working in confined engine bays or electrical panels. The hollow round shank slides over protruding threads. A blue cushion grip reduces hand fatigue during repetitive use.
Clearance And Magnetic Limits
Bolt clearance is 7/32 inch, so longer studs pass through the hollow shank without bottoming out. The tip is non-magnetic and will not hold a nut in place during positioning. It is not ESD safe and carries no insulation rating, restricting use around live circuits or static-sensitive assemblies. California Proposition 65 warnings apply to this product.
Installation And Common Issues
The driver seats directly onto the fastener; no bit holder or adapter is required. Users sometimes expect the tip to retain the nut, but the non-magnetic design means the fastener can fall off if tilted. The hollow shank can accumulate debris in dirty environments, so occasional cleaning maintains a clean fit.
