STANDARD CONFIGURATION - FASTENER TENSILE

First, locate your machine model and serial number. Now work through the following steps: 1 FASTENER Start by determining the size of the fastener(s) to be tested. This would include the diameter, thread pitch and length for each unique fastener to be tested. * Consult Instron when the fastener is high strength, and/or if dynamic testing will be performed 2 HOLDER The holder is then selected by using the smallest and largest fastener size. If the range spans two or more Holder Series, then you will want to consider to piggyback* one holder to another. However, this is dependent on the available tensile test space. * See page 30 for piggyback adapters 3
WASHER/SHORT BOLT ADAPTER
SPHERICAL TENSION ADAPTER
If a Spherical Tension adapter is already present, please provide the thread size of the tension rod to determine if additional adapters may be required to install the fastener fixtures.
If a Spherical Tension adapter is not available, we will help you to determine the appropriate one for the specific machine model and serial number.
Now, select the washers* to match the fasteners with respect to the Holder Series that you selected in Step 2 and the test type shown in the section below. Standard Washers are ASTM F606 compliant; if ISO 898 compliance is required, note this at inquiry. * See pages 31 - 34 for types of washers
A spherical tension adapter is recommended to provide compensation for minor misalignment, hence minimizing the stresses to the fastener that could result in premature failure.
Additional adapters may be required. This will be determined through the steps above.
