Venting Stainless Steel Hex-Drive Flat Head Screws
 |
 |
Prevent the buildup of pressure or vacuum in sealed spaces. These screws have a hole drilled through their center that lets air, fluid, and gases escape. They're often used to release trapped gases and equalize pressure caused by high temperatures in coating, curing, and heating applications. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. 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 Profile—Standard-profile heads are the most common choice for flat head screws.
