Installation & Operating Instructions

AA06-100-001 IVB Fastener

Usage of your IVB fastener requires simple preparation of the "holding" side for the housing threads and preparation of the "receiving" side for the stud threads.

Prepare the "holding" side in the following manner:

Drill a 63/64" diameter hole.
C'Bore 1.000" x .03R to a depth of 1.200"
Tap Drill 1 11/64" diameter hole. Tap (or thread) 1 1/4"-12
UNF-2B-LH to a depth of .500"
To install the IVB Fastener: Simply place the spring into the "holding" side hole, place the stud on top of the spring (threads facing out of the hole). Use the AA03-002-002 install tool, screw the 1 1/4" diameter cap into the 1 1/4"-12 threaded hole until it bottoms out in the hole. Note: you will have to "force" the stud down through the hole of the cap with the install tool in order to screw it down flush.
Prepare the "receiving" side for the stud threads:

Tap Drill thru using 17/32" diameter drill. C'Sink .70" dia. x 45 degrees. Tap (or thread) 5/8"-11 UNC-2B x .60" deep. For better resistance against vibration, use a Spiralock® tap.

Place the "receiving" side 5/8"-11 tapped hole directly above the IVB fastener. Reach through the 5/8"-11 hole with your hex head wrench until contacting the hex head broach in the IVB stud. Start turning counter-clockwise. The stud will proceed into the 5/8"-11 tapped hole. Tighten until the stud is fully engaged (approximately .50" inches into the "receiving" side). Use a feeler gauge to insure that the "receiving" side material is pulled down properly.

General

Your Invert-A-Bolt™ (IVB) fastener has been manufactured to provide low cost, high value performance combined with ease of use. This, made in the U.S.A., fastener is designed to provide the basic characteristics of the Invert-A-Bolt™ concept with the exception that the stud is contained by the mill fixture rather than by an outer housing. To make use of the IVB fastener, simply prep the fixture and insert the components as described in the "Operating Instructions".

Replacement Parts & Maintenance

1. Replace internal components (stud and spring) as required by ordering AA06-100-001RFB Refurbishment Kit.

2. Periodically remove the cap of the IVB fastener, blow out the hole, to clean out accumulated metal chips and debris.

Proviso's

This fastener is not recommended for applications in which the stud is screwed down completely and milling occurs above the fastener. This fastener is not designed to keep the stud down at any time.

The IVB fastener is not certified to any specification. If loading is a concern, you should perform your own load analysis prior to usage in an application. Shear & Tensile Load information for some Invert-A-Bolt™ products is available at the FAQ page. The IVB fastener should be used in only two positions – fully engaged and fully dis-engaged.
