Pull-up bolt assembly

The method of making a pull-up bolt assembly for use to frictionally support a manway cover to a hinge component using an opening or recess in the manway cover, the method comprising:

• obtaining a pull-up bolt having a threaded shaft with a first shaft end and a second shaft end, and an abutting member with a tapered surface formed at the first shaft end, the abutting member being wider than and tapering toward the threaded shaft;
• slidably disposing an expandable friction member around the threaded shaft wherein a first outer end of a first outer end portion is positioned against the tapered surface of the abutting member;
• threadably connecting a nut component with an external torque-applying surface onto the threaded shaft of the pull-up bolt wherein a tapered member with a tapered end portion, a flange disposed between the external torque-applying surface of the nut component and the tapered end portion and a cylindrically-shaped portion between the tapered end portion and the flange wherein the tapered end portion faces toward the tapered surface of the abutting member and engages a second outer end of a second outer end portion of the expandable friction member whereby at least the first outer end portion and the second outer end portion of the expandable friction member expands when the nut component is threadably moved toward the abutting member of the pull-up bolt.
