These are custom oval point set screws made domestically in the USA using 18-8 stainless steel material. While this 1/2-13 X 1" size is fairly common off the shelf in a cup point version, the oval point is a tough find and typically requires a special production run. We were able to get these set screws completed within 1 week at 100 pieces. Material certs and our certificate of conformance was available with the parts.
