Abstract: Apparatuses and methods for structurally testing fasteners are described herein. A fastener test apparatus configured in accordance with one aspect of the invention includes a first support member configured to support a head portion of a fastener, and a second support member configured to support a locking feature on a shaft portion of the fastener. The test apparatus can also include a force measurement device configured to be operably sandwiched between the first support member and the second support member. The force measurement device can be used to measure fastener preload. The test apparatus can further include first and second fixtures for performing an ultimate tensile test of the fastener. In this regard, the first fixture can be configured to exert a first force against the first support member in a first direction, and the second fixture can be configured to exert a second force against the second support member in a second direction opposite the first direction.
