SO™/SOS™/SOA™/BSO™/BSOS™/BSOA™ STANDOFFS

(1) Published installation forces are for general reference. Actual set-up and confirmation of complete installation should be made by

observing proper seating of fastener as described in the installation steps. Other performance values reported are averages when all

proper installation parameters and procedures are followed. Variations in mounting hole size, sheet material, and installation procedure

may affect performance.  Performance testing this product in your application is recommended.  We will be happy to provide technical

assistance and/or samples for this purpose.

(2) See tech sheet on our website for performance data of PEM® Type SO™ standoffs installed into copper sheets.

(3) Joint failure in torque-out and pull-thru will depend on the strength and type of screw being used. In some cases the failure will be in the screw

and not in the self-clinching standoff. Please contact our Applications Engineering group with any questions.
