Stainless Steel Hex-Drive Flat Head Screws
 |
The most corrosion-resistant hex-drive flat head screws we offer. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals, but they're not as strong as alloy steel. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver without slipping and stripping the drive.
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—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.
