Tubing clamp and method of making the same

Claim 1

A clamp for securing a cylindrical member comprising a first clamp half and a second clamp half having inner and outer sides for encircling the cylindrical member, the first clamp half and second clamp half having means at their ends for interlocking with a channel member and having apertures of a substantially equal diameter formed at their opposite end for receiving a stud, said stud comprising an elongated member having a longitudinal axis, a head portion at one end abuttingly engaging the outer side of the first clamp half and externally threaded portion at the opposite end for receiving an internally threaded nut abuttingly engaging the outer side of the second clamp half to tighten the first clamp half and second clamp half about the cylindrical member, and an elongated spacer coaxial with the longitudinal axis of said elongated member and integral with said elongated member interposed between said head portion and said externally threaded portion, said spacer having a diameter greater than the diameter of said apertures forming first and second spaced apart parallel shoulders perpendicular to the longitudinal axis of said elongated member, the inner side of the first clamp half being squarely abutted against the first shoulder and inner side if the second clamp half being squarely abutted against the second shoulder when said internally threaded nut is tightened against the outer side of the second clamp half, said first and second shoulders preventing the first clamp and second clamp half from being tightened to the extent that they damage the conduit or bend the side, said head portion being pressed against the outer side of said first clamp half tightly restricting the first clamp half between said head portion and said first shoulder, said stud being restrained from turning within the aperture in said first clamp half, wherein said head portion further comprises a serrated section adjacent said first shoulder receivable by said aperture in said first clamp half, said serrated section preventing said stud from turning within said aperture.
