Benefits #
At 1/2-inch, inch-series grub screws provide headless shaft locking in US-specification equipment and aerospace assemblies. The cup point concentrates force on a small contact area, producing reliable indentation-based locking. The headless form installs below the surface, critical where external heads create interference with adjacent components. ASME B18.3 standardisation ensures dimensional interchangeability. Class 3A thread tolerance provides proper fit in inch-tapped holes.
Common Applications #
Typical applications for 1/2-inch inch-series grub screws:
- Aerospace and defense equipment
- Industrial valve and actuator assemblies
- Hydraulic cylinder manifold assemblies
- Conveyor roller fixation (inch bores)
- Heavy-duty US-spec coupling assembly
