M8 x 25mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel
Developed for industrial test rigs and clamping assemblies, this M8 x 25mm knurled machine thumb screw combines a 1.25mm metric thread with the low-profile head form associated with DIN 653. The knurled edge improves fingertip control during frequent assembly and the 25mm thread is suited to additional threaded reach through thicker components or spaced assemblies.
What Are Thin Knurled Thumb Screws?
Thin thumb screws provide convenient tool-free fastening where speed and accessibility matter. Their flat knurled head is easier to grip than a plain machine screw yet remains lower in profile than high-type thumb screws used when greater hand leverage is required.
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.
