HeadLOK is a heavy duty wood screw that does it all with an internal drive and flat head. HeadLOK offers higher design shear than 3/8" lag screws and no predrilling is needed.
No Pre-Drilling Required
Installs in a fraction of the time versus traditional bolts with fewer steps and less effort.
Black Flat Head Design
The flat head installs flush saving additional time and money. Combined with the black coating on the fastener, HeadLOK provides a great finished look.
ACQ Approved & Code Compliant
Tested and supported by engineering data that conforms to the most current ICC standards. It is also approved for use in ACQ or treated lumber.
