Mudsill Plate to Increase Foundation Bolt Strength and Reduce Splltting

MUDSILL PLATES INCREASE BOLT STRENGTH AND HELP PREVENT SPLITTING OF THE MUDSILL

 

House Bolt Strength and Mudsill Plates

Mudsill Plates were invented by Harlen Metal Products after the Northridge Earthquake to increase bolt strength and to reduce mudsill splitting caused by oversized holes, a phenomenon which is discussed below.
Thousands of homes had split mudsills for two reasons: the bolts simply were not strong enough and secondly they were miss-installed with over sized holes.
