Stainless Steel Phillips Flat Head Screws
 |
These screws are made of stainless steel, so they won't rust or corrode when exposed to moisture and chemicals. The Phillips drive has a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.
Length is measured from the top of 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.
Standard Profile—Standard-profile heads are the most common choice for flat head screws.
Military Specification—These screws are manufactured and tested to meet strict U.S. military standards for material and construction.
