Vented Hex Head Screws
Vented Hex Head Screws
The Solution for Trapped Gas | Maximize Vacuum Efficiency | 18-8 Stainless Steel
Product Overview
These Vented Hex Head Screws are precision-drilled with a continuous hole running through the head and shank. This engineered feature is essential for high-vacuum systems, pressure vessels, and critical fluid assemblies, as it allows trapped gases and fluids to vent and escape from blind tapped holes.
Fabricated from Corrosion-Resistant 18-8 Stainless Steel, these fasteners guarantee long-term reliability and performance in demanding industrial and laboratory environments.
Core Features & Benefits
| Feature | Benefit (Why it Matters) |
| Through-Hole Venting | Drastically reduces vacuum pump-down time by eliminating trapped air pockets. Essential for pressure equalization and fluid drainage. |
| 18-8 Stainless Steel | Exceptional corrosion and rust resistance, ideal for sanitary, washdown, and harsh environments. |
| Standard Hex Head | High-torque installation and easy removal using common tools, simplifying maintenance. |
| Thread Options | Choose Fully Threaded for maximum clamping force or Partially Threaded for greater shear strength and precise component alignment. |
Critical Applications
Vacuum Chambers: Ensures rapid system evacuation.
Fluid Power Systems: Used in hydraulic and pneumatic manifolds to bleed air and ensure smooth operation.
Scientific & Laboratory: Essential for high-spec equipment like mass spectrometers and vacuum ovens.
Sanitary Environments: Provides complete drainability in Food, Beverage, and Pharmaceutical processing.

FAQs
Q: How fast will this reduce my pump-down time?
A: By providing a direct escape route for air trapped beneath a standard screw, a vented screw can significantly and measurably reduce the time required to achieve ultimate vacuum levels.
Q: Are these suitable for high-pressure systems?
A: They are effective for equalizing trapped pressure volumes during system startup. They are not certified or rated as pressure relief valves. Always consult an engineer for critical pressure system design.
