Abstract: A clamp tie includes a locking head and flexible straps extending therefrom. The straps are insertable through the locking head to form spaced loops, which may secure items in a spaced relationship. Pawl mechanisms in the locking head secure the straps in looped configuration. An aperture through the locking head is provided for securing the tie to a mounting structure such as a shouldered mounting stud. An additional pawl mechanism may be provided within the aperture to secure the tie to the stud. Arcuate surfaces extend from the locking head, spaced from the straps, to further engage secured items. The upper and lower surfaces of the locking head have counterbores to receive mounting hardware and provide minimal variance of wall thickness throughout the locking head to reduce cure time and materials required for manufacture.
