Fastener combinations were mated, then disengaged at a rate of 12 inches (305mm)/minute. Tests were conducted under controlled laboratory
conditions at 72°F (22°C), 50% R.H.

Fasteners were attached to aluminium and stainless steel panels and engaged in the combinations listed. Tests were conducted at the
temperatures and gram loadings listed. Tests were discontinued after 10,000 minutes (7 days).
NOTE: In static load applications, conditions such as temperature variation, vibration, jarring, etc. Can affect long term performance. The user
should design the amount of fastening area based on specific conditions in the application. Four square inches of fastening area per pound of
static load is suggested as a starting point for evaluation.
