摘要： A compression generator uses a plurality of jackbolts threadedly engaged at a spaced apart relation about a bolt circle in a main core element. The main core element is releasable interlocked by threads, bayonet connection or other form of fasting system with the mounting element forming a fixed part of the mechanical connection. The jackbolts torqued to generate a pushing force in an axial direction for compressing a moveable part of the mechanical connection against a compression seat for forming a mechanical connection between juxtaposition fixed and moveable parts.

摘要： A multi jackbolt tensioner including a jackbolt body having a plurality of holes with threads to receive jackbolts having torque receiving surfaces all disposed about the periphery of each jackbolts in a mutually non parallel relation to prevent the unauthorized application of torque or stress. The torque receiving surfaces of each bolt head are defined by vertices at the intersect of n number of unsymmetrical arranged torque receiving surfaces of a polygon, where n is an odd integer.

摘要： A fastener includes a threaded circular ring half divided along a plane intersecting a central longitudinal axis. One of the end walls is formed with a truncated conical load-bearing surface that is seated on a truncated conical thrust surface formed on a circular ring of a stress generator. The load bearing and thrust generating surfaces are arranged to present a conjugate pair of truncated conical surfaces to provide a favorable resolution of forces developed by torque applied to jack bolts distributed about an outwardly surrounding cylindrical stress generator body section.
