Prevent the buildup of pressure or vacuum in sealed spaces. The hole in the center of these corrosion-resistant screws allows air, gas, and fluid to escape. These screws are often used to equalize pressure from high temperatures during coating, curing, and heating. The deep, six-point socket keeps hex keys from slipping out and damaging the drive.
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 screws can.

Cleaned and Bagged Venting Socket Head Screws for High Vacuum
 |
 |
Reduce the time it takes to reach vacuum conditions in high-vacuum systems. A vent in these screws allows fluid and gas to escape. Cleaned and double-bagged in an ISO Class 5 (Fed. Std. Class 100) clean room, use them these screws in places where even a small amount of contamination could affect performance. The deep, six-point socket keeps hex keys from slipping out and damaging the drive.
Length is measured from under the head.
18-8 Stainless Steel—Release gas at a slower rate than other metals, allowing your system to achieve higher levels of vacuum.

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.
