⚡ At a Glance
  • Holding Strength: Knurled heads and standard metric threads deliver secure thumb-tight fastening
  • Best for: DIYers, furniture makers and home maintenance tasks requiring easy manual adjustments
  • Not ideal for: High-torque assemblies or applications requiring sealed, permanent fixings

Made from 304 stainless steel, thumb screws are available in M3, M4 and M5 thread sizes. Length options range from 6mm to 30mm and packs come as two or five pieces for flexible use.


Quick, tool-free adjustments - with knurled head for fingertip grip

Knurled head surfaces create friction under fingertip pressure, allowing tightening and loosening without tools. Flat or round head profiles change how the fastener sits against surfaces.

Fingertip control speeds small assembly and adjustment tasks, ideal for furniture panels and access panels. Head options help achieve either a low profile or a slightly protruding finish.

Long-lasting corrosion resistance - thanks to 304 stainless steel

304 stainless steel resists rust and staining under normal indoor and outdoor conditions, maintaining thread integrity over time. Material choice reduces the likelihood of seizing or galling on repeated use.

Screws stay serviceable through routine wear and humidity, reducing replacements. Suitable for kitchens, conservatories and sheltered outdoor spots where moisture exposure occurs.

Fits a range of projects - with multiple thread sizes and lengths

Available sizes include M3, M4 and M5 threads and lengths span 6mm to 30mm, covering thin panels to thicker assemblies. Two or five piece pack options match small repairs or larger jobs.

Range of sizes makes it straightforward to match panel thickness and thread fit without custom ordering. Choice of pack quantity helps avoid leftover stock or mid-job shortages.
