M8 x 18mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel
Ideal for equipment covers requiring repeated maintenance access, this M8 x 18mm low-profile thumb screw provides a controlled hand-operated fixing with a 1.25mm pitch and 18mm threaded section. The broad 30mm knurled head improves grip while the thin 6.0mm 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
- Workshop Machinery: Secures adjustable components where controlled hand tightening is sufficient.
- Production Equipment: Supports repeat access to changeover parts and removable hardware.
- Engineering Fixtures: Provides hand-operated fastening for robust jigs and production tooling.
- Machine Guards: Secures larger covers that require repeated removal for maintenance.
