Thumb Screw

Thumb screws are knurled and have a large head to allow for easy installation and removal. They are used in applications that require frequent access such as an air-conditioning filtration enclosure. They are designed to be finger tight and no tools are required to remove them, therefore torque is limited to finger strength. 


They are available in metric as well as standard threads and various lengths.  They are available in 3 styles: Washer Face that spaces the head above the receiving surface, Plain that has no shoulder and meets flush with the receiving surface and Push Type with a head of the same diameter of the threaded section. 


They are available in brass, aluminum, steel and stainless.
