Machine Screw 8-32 x 1/2" P-PH-Taptite
Machine Screw 8-32 x 1/2 inch Phillips pan head with Taptite® threads.
The triangular shank presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper. Also known as Taptite® screws, they have a pan head with a flat bearing surface and a blunt tip. Length is measured from under the head.
