Machine Screw - Slotted Truss Head - 18-8 Stainless Steel - 1/4"-20 Thread - 3" Long - Pack of 500

Machine screws are typically used with a pre-tapped hole or with a nut. The truss head has a curved surface, extra-wide profile, and a lower profile than most pan head screws. The extra-wide top helps prevent the screw from going through the drilled surface. The slotted drive has a straight-line notch grooved into the surface the head and is designed to be used with flat-headed screwdrivers. 18-8 stainless steel, also commonly known as 304 or A2 stainless steel, has good chemical resistance and may be mildly magnetic.
