M4 x 16mm Thin Knurled Thumb Screw (DIN 653) | A1 Stainless Steel
Manufactured to DIN 653, this M4 x 16mm DIN 653 thumb screw is suited to optical equipment and test rigs. Its finely knurled 16mm head can be tightened and released by hand and the low 3.5mm profile keeps protrusion to a minimum where space around the fixing is restricted.
What Are Thin Knurled Thumb Screws?
DIN 653 thumb screws use a slim circular head with external knurling so the fastener can be tightened and loosened by hand. They are particularly useful on access panels, fixtures and instruments where a conventional screwdriver or hex key would slow routine adjustments.
Common Applications
- Display Systems: Supports repeated assembly and dismantling of exhibition or demonstration hardware.
- Bench Instruments: Keeps service covers accessible without relying on a screwdriver.
- Test Rigs: Fastens repositionable components during setup and calibration.
- Light Machinery: Provides hand-operated fixing for small guards and access plates.
