The GIBRALTAR 27ST-H SCP SET is a thread clamp screw assembly with a multi-pad, designed for secure clamping applications in trade and industrial settings. The screw features a TM18x5.0 thread size with a 5.1-inch thread length, providing reliable grip and holding force across compatible clamp bodies. This hardware set is typically installed by millwrights, pipefitters, machinists, or maintenance technicians working with clamp-style fastening systems. The included multi-pad distributes clamping force across the work surface to reduce marring and improve contact stability. At 0.42 pounds, the set is compact and easy to handle during installation.
This clamp screw and multi-pad set is intended for use with Gibraltar L and F style clamps in workshop, production, and mechanical assembly environments. It is suited for both bench-top and in-line clamping tasks where a replaceable or upgraded screw-and-pad configuration is needed. The TM18x5.0 thread specification makes this a targeted replacement or supplemental hardware component rather than a general-purpose fastener.
Designed for use with Gibraltar L and F Clamps as specified by the manufacturer.
Installation of this clamp screw set should be performed by qualified technicians familiar with clamping hardware. Disengage and fully release any load from the existing clamp assembly before removing or replacing the screw and pad. Thread the screw by hand to confirm proper engagement before applying torque with a wrench or handle. Inspect threads on both the screw and clamp body for damage or debris before reassembly.
