Abstract

A mechanical fastener assembly is provided for joining two or more workpieces. The assembly includes a mechanical fastener and a slotted collar. The mechanical fastener has a shaft received within aligned bores of the workpieces, while the slotted collar surrounds at least a portion of the shaft and is also received within the aligned bores. Inserting and advancing the slotted collar into the aligned bores causes the slot of the slotted collar to at least partially close, thereby causing an inner surface of the slotted collar to engage at least a portion of the shaft of the mechanical fastener and an outer surface of the slotted collar to engage at least a portion of the aligned bores of the two workpieces. Such a mechanical fastener assembly can effectively transform a bolted joint into a stronger shear joint.

Description

[0001] related application [0002] This application claims the benefit of and priority to US Nonprovisional Patent Application Serial No. 13 / 834,318, filed March 15, 2013, which is incorporated herein by reference. technical field [0003] This topic is about bolted connections. More particularly, the subject matter relates to methods and systems for strengthening bolted joints. Background technique [0004] It is well known to secure two or more parts of an assembly together through the use of mechanical fasteners. Bolts and rivets are among the typical mechanical fasteners used depending on several factors. Each mechanical fastener has advantages and disadvantages. Bolts are generally more serviceable than rivets, as they are usually easily inserted and removed as needed, whereas rivets are generally not intended to be removed and repaired. In contrast, riveted connections are generally stronger than bolted connections because bolts create only friction between the pa...
