Stainless A4
Stainless flat point grub screws (set screws) are headless, fully threaded fasteners with a flat tip used to secure components like gears or pulleys onto shafts without damaging them.
Made from durable A2 or A4 stainless steel, they feature a hexagonal socket drive, often conforming to DIN 913/ISO 4026 standards, and are ideal for high-precision, low-damage, or corrosion-resistant applications
