ABSTRACT:
A T-shaped bolt for use in securing two slotted members--such as an upright post and a horizontal beam in a pallet storage rack--to each other. The tee head of the bolt is dimensioned to be inserted in a pair of aligned slots of the two members that are to be secured to each other, and then rotated so that the ends of the tee head abut edge portions of the slot in the first slotted member, with the threaded shank of the bolt extending out through the slot in the second slotted member. The nut to be threaded on the bolt is a torque resistant nut, and thus when it is first turned it will cause the bolt to rotate until its specially shaped neck abuts the edges of one or both slots. At this point, the application of a predetermined minimum torque causes the nut to be turned further upon the bolt, until it is turned up tight against the second member and secures the two slotted members to each other.
