ASME/ANSI B18.6.2 (T5 oval):1998 Slotted Oval Point Set Screw uses a rounded oval point that provides gentler contact with the mating part, making it suitable for positioning joints where obvious cutting or scratching should be avoided.
The oval point offers better adaptability when there is slight angular misalignment or an uneven contact surface. It is useful for adjustment parts, knobs, sliders, and light stop structures. The slotted drive keeps tool requirements simple and supports quick service work.
This product can be used in instruments, office equipment, small machinery, fixture adjustment, and electromechanical devices. Stainless steel, carbon steel, or plated material options can be selected to meet requirements for surface protection, corrosion resistance, and cost control.
