Applications & Industries for M5 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 M1.6 to M10.
Industries that specify Knurled Thumb Screws
-
Laboratory & test rigs
Clamps and panels adjusted during a run.
-
Photography & AV
Mounts and brackets set by hand.
-
Machine guarding
Covers opened by an operator without a tool.
-
Jigs & fixtures
Setups changed several times a shift.

-
Machine guarding
Covers and guards opened by an operator without a tool.
Typical applications
- assemblies adjusted many times a shift
- hand-tightened clamping
- 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
- Not for a joint that needs a defined clamp load; a hand-tightened screw carries only what a hand can produce.
