Mil. Spec. Wire-Locking Stainless Steel Fillister Head Slotted Screws
 |  |
Manufactured and tested to meet strict U.S. military specifications for material and construction. Secure a wire through the hole in the head of these screws to lock them in place. They handle more vibration and movement than screws with threadlocker or lock washers, but they're harder to install. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. With a deeper drive than other rounded head styles, 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.
Stainless Steel Wire—Thread this stainless steel wire through screws to lock them together.
