Product Description
1/4"-26 BSF Brass Slotted Cup Point Grub Screws – 3/8" Long
These brass cup point grub screws feature a 1/4"-26 BSF thread and a slotted drive. Their headless design allows them to sit within a threaded hole, making them useful for adjustment and component retention where a projecting screw head is unsuitable.
The cup point provides a recessed tip with a circular contact edge that bears against the mating component. These screws suit repairs, maintenance and restoration work requiring a matching British Standard Fine thread.
