M4 x 18mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel
Ideal for display systems and removable access plates, this M4 x 18mm low-profile thumb screw provides a controlled hand-operated fixing with a 0.70mm pitch and 18mm threaded section. The broad 16mm knurled head improves grip while the thin 3.5mm head height suits compact equipment and visible assemblies.
What Are Thin Knurled Thumb Screws?
The defining feature of a DIN 653 fastener is its thin knurled head. Its textured circumference provides grip for fingers while the metric thread engages a matching tapped hole or nut, allowing components to be secured and released without a separate driver.
Common Applications
- Test Rigs: Fastens repositionable components during setup and calibration.
- Light Machinery: Provides hand-operated fixing for small guards and access plates.
- Control Enclosures: Secures removable panels that need routine operator or maintenance access.
- Optical Equipment: Provides tool-free fastening for adjustable mounts and compact assemblies.
