Product Details
The B1/4-20 x 3/4" machine screw is a flat head, slotted steel fastener with a zinc CR+3 finish, provided in a package of 100 units under the BBI 580623 designation. These machine screws are designed to pass through a pre-tapped hole or nut to engage a mating thread securely. The flat head design ensures that the fastener does not protrude above the mating surface, making it suitable for applications requiring flush installation. The screws measure 3/4" in length with a 1/4-20 thread size, offering reliable fastening with corrosion resistance due to the zinc CR+3 plating. Warranty terms are provided with the product, guaranteeing quality and performance.
