They have an easy grip head that allows for simple by hand installation, just like conventional thumb screws. The large panel screw has an extra large head with a straight knurled surface for additional grip for manual adjustment. These quality crafted thumb screws provide quick installation for securing cases and can easily be tightened by hand without much force. Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness.
