Corrosion and vibration resistant, these pan head screws secure parts in place on machinery with mild vibration. With a nylon-patch threadlocker bonded to the threads, they save you the time and mess of adding it yourself. Pan heads have a moderate height and width profile, offering a middle ground between narrower button heads and wider truss heads. The Phillips drive easily aligns with drivers and withstands more torque than slotted drives, but drivers slip when you apply too much force.
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.
