Modular system with captivated fastener assemblies

A modular system, comprising:

• a first body having a throughbore;
• an insert adapted to threadably couple to the first body;
• and
• a fastener disposed within the throughbore, wherein the insert and the first body cooperate to retain the fastener entirely within the throughbore, wherein a first end of the insert comprises a male thread and a second end of the insert comprises a female thread.

A modular system, comprising:

• a first base comprising:
• a body having a throughbore;
• a fastener disposed within the throughbore;
• and
• an insert having a first end adapted to threadably couple to the body and a second end that extends out of the body;
• and
• a second base adjacent the first base, the second base having an opening that receives the second end of the insert to align the second base with the first base.

A method for connecting modules in a modular flow system, comprising:

• disposing a first fastener within a bore in a first module;
• threadably coupling an insert to the first module such that the insert and the first module cooperate to retain the first fastener within the bore, wherein an end of the insert extends out of the first module;
• placing a second module adjacent the first module such that an opening on the second module receives the end of the insert to align the first module with the second module;
• and
• engaging the insert with a second fastener associated with the second module to attach the first module to the second module.

A modular flow system, comprising:

• a first body having a throughbore;
• a fastener disposed within the throughbore;
• a single-piece insert having a first end adapted to couple to the first body and a second end that extends out of the first body and is adapted to be received in an opening on a second body, which is adjacent the first body, to align the second body with the first body;
• wherein the single-piece insert and the first body cooperate to retain the fastener with the bore.

An assembly method for modules in a modular flow system, comprising:

• attaching an insert to a bore in a first module, wherein an end of the insert extends out of the first module;
• placing a second module adjacent the first module such that a bore in the second module receives the end of the insert to align the first module with the second module;
• inserting a fastener within the bore of the second module;
• and
• attaching the fastener to the end of the insert that is within the bore in the second module to secure the first module to the second module.

A modular flow system, comprising:

• a first body having a throughbore;
• a fastener disposed within the throughbore, the fastener adapted to couple to a second body to attach the first body to the second body, and
• an insert having a throughbore, a first end adapted to couple to the throughbore of the first body, and a second end that extends out of the first body and is adapted to be received in an opening on a third body to align the third body with the first body,
• wherein the fastener is accessible through the throughbore in the insert to decouple the fastener from the second body while the insert is coupled to the first body.
