Large washer head provides maximum bearing area; stamped with the Simpson Strong-Tie sign and fastener length for easy identification after installation (0.760-in. head diameter)
SawTooth point ensures fast starts, reduces installation torque and eliminates the need for predrilling in most applications
Deep 6-lobe T40 recess reduces cam-out, making driving easier
Low-profile head results in less interference after installation; makes stacking and sliding members easier and allows installation of hardware and finishes to be virtually flush
Higher shear values than competitive products enable wider spacing, saving time and money
