M5 x 30mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel
Ideal for display frames and adjustable brackets, this M5 x 30mm low-profile thumb screw provides a controlled hand-operated fixing with a 0.80mm pitch and 30mm threaded section. The broad 20mm knurled head improves grip while the thin 4.0mm head height suits compact equipment and visible assemblies.
What Are Thin Knurled Thumb Screws?
Thin knurled thumb screws are manually operated fasteners intended for assemblies that are opened, adjusted or repositioned without tools. The round head is textured around its edge to improve finger grip while the thin DIN 653 profile reduces head height compared with taller thumb screw styles.
Common Applications
- Workshop Fixtures: Fastens adjustable parts that operators need to release regularly.
- Test Equipment: Provides controlled hand fastening for fixtures used during repeated trials.
- Machine Panels: Secures service panels that are removed during inspection or maintenance.
- Production Jigs: Allows stops, guides and fixture parts to be repositioned without tools.
