Nonmagnetic L-Keys

Fasten screws in everything from MRI machines to semiconductor equipment without worrying about magnetic interference. These L-keys are made from nonmagnetic titanium, so they won't damage electrical components or attract loose metal parts and shavings in your toolbox. With the best strength-to-weight ratio of all our L-keys, they're as strong as steel to resist bending under high torque and weigh up to 50% less.

Long—The most common option, these L-keys have a balanced length for everyday reach and torque.

Nonmagnetic Screwdrivers

These drivers safely fasten screws on everything from MRI machines to semiconductor equipment without getting pulled inside by strong magnetic forces. The grade 5 titanium shaft is nonmagnetic and resistant to many chemicals.

Also ideal for industrial maintenance, these no-frills screwdrivers withstand years of heavy use in the shop and on the jobsite. The hard plastic handle won't crack or wear out from drops and scrapes. It's also easy to wipe down and won't get sticky or gummy when exposed to oils or chemicals, unlike a soft handle.

Standard Length—The most common screwdriver length for a specific drive size.

Premium—The best screwdrivers available, with tips machined to tight tolerances for the tightest possible fit in fastener recesses. The snug fit means they'll turn screws quickly without wearing screw heads and the driver's tip.
