摘要
A jackscrew nut and/or bolt head assembly includes a bottom washer that is interlocked via circumferentially arrayed castle extensions and recesses. Spherical faces at the washer top are thereby held in alignment with corresponding spherical jackscrew bottoms, which assures evenly distributed contact pressures during out of angle elastic jackscrew displacement during jackscrew loading. The bottom washer interlock may provide further for a transfer of a primary pre tightening torque exerted onto the main body of the nut and/or bolt head via a tool that concurrently accesses all jackscrew heads extending above the main body. The assembly may be initially tightened via the primary torque whereby secondary jackscrew actuation and displacement is greatly reduced. The jackscrews are thinned in reverse for maximum contact area at their spherical bottoms.
