The best vibration resistance of our rounded head screws. Secure a wire through the hole in the head of these screws to lock them in place. Unlike screws with threadlocker or lock washers, they handle more vibration and movement, but they're more difficult to install. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. With a deeper drive than others, fillister heads reduce the likelihood that basic slotted drivers slip as you hand-tighten them.
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 can.
Military Specification—These screws are manufactured and tested to meet strict U.S. military standards for material and construction.
Stainless Steel Wire—Thread this stainless steel wire through screws to lock them together.
