Applications & Industries for M10 Knurled Thumb Screws
Knurled Thumb Screws are bought for a small number of well-defined jobs. These are the ones we ship them for. Stocked from M1 to M10.
Industries that specify Knurled Thumb Screws
-
Display systems
panels changed without tools.
-
Electronics
covers and card retainers opened by hand.
-
Photographic equipment
mounts and plates.
-
Workholding
light clamps and stops.
-
Laboratory & test equipment
Panels and clamps adjusted by hand during a run.
-
Machine guarding
Covers and guards opened by an operator without a tool.
Typical applications
- replacing screws that are lost when a tool is needed
- tool-free assembly in tight spaces
- adjusting position repeatedly
- holding light covers and plates
- adjustment that has to be made by hand while the machine runs
- tool-free opening and closing of a panel or clamp
Service conditions to specify against
- Marine and coastal
- Available in A4 (316) stainless for chloride exposure — coastal structures, pool halls, water treatment and deck hardware, where A2 will eventually pit.
Where to use something else
- Do not expect clamp force from a low knurled head; the small grip limits torque to light duties.
- Not for a joint that needs a defined clamp load; a hand-tightened screw carries only what a hand can produce.
