Benefits #
The 3/8-inch inch grub screw serves shaft-locking applications in imperial-dimensioned assemblies where metric fasteners are not interchangeable. Cup point geometry creates a positive mechanical lock without keyed connections, simplifying shaft-to-component fixation. Internal hex drive allows installation with standard Allen keys. Hardened alloy steel maintains cup point effectiveness on carbon steel and alloy shafts. UNC coarse threads provide reliable engagement in standard inch-tapped holes.
Common Applications #
3/8" inch grub screws are specified for shaft-locking in US-specification equipment:
- Legacy US-specification machinery
- Shaft-to-collar locking on inch shafts
- Pulley fixation on imperial shafts
- Door handle and lockset hardware
- Automotive powertrain components
