Drop Prevention Socket Head Screws for Ratchet Wrenches
 |
 |  |
Fully Threaded | Partially Threaded |
Avoid dropped fasteners when working on overhead assemblies and in hard-to-reach spaces. The square drive of your ratchet wrench grips the screw until you release it. This reduces the chance of dropping fasteners and helps you comply with foreign object debris (FOD) programs.
Length is measured from under the head.
18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel screws can.
