McMaster 9597N112 3/8" Square Drive Foreign Object Damage (Fod) Prevention Ratchet Wrench

With no internal screws, these ratchet wrenches don’t have a single small part that could fall into and damage equipment. They help you comply with Foreign Object Damage (FOD) prevention plans to shield sensitive machinery, such as engines and electronics, from damage. For added protection against falling parts, a positive-locking push button ensures you don’t release your socket during use.
