VENTED SCREWS

When a screw is inserted into a blind tapped hole, a small pocket of gas will be trapped below the screw, this pocket of gas will give rise to a ‘virtual’ leak within your system. The use of vented screws will allow the pocket of gas to escape thus avoiding ‘virtual’ leaks. We offer a broad range of vented screws in many different styles and sizes. Just a small selection are listed here. If the style of screw or size that you require is not listed, please contact our sales office.
