FastenMaster Fastening System
ThruLok Screw Bolt
ThruLok is a three part assembly including a ThruLok fastener featuring the patent pending Paddle Point™, engineered washer, and LOK-Nut. The ThruLok fastener comes in specific lengths that allow contractors to replace their ½” carriage and through bolts in three primary deck applications:
- 6 ¼” fastener – Single 2x to 4x Decking Posts
- 7″ fastener – Notched 6x Carrying Beams
- 8″ fastener – Double 2x to Single 4x Decking Posts
Every box contains a technical bulletin, showing builders how to fasten the application in a code compliant manner. To install, simply drive the ThruLok fastener until it reaches ¼-in. before flush, reach around to threads protruding out the back and hand tighten the LOK-Nut, come back on the other side and finish your drive. The patent pending Paddle Point feature requires no pre-drilling and will tighten itself into the LOK-Nut providing a secure connection and saving time and labor in the process.
In addition, each ThruLok fastener comes assembled, in either a 6 or 24 pack complete with a magnetic 5/16″ driver bit and extra washers. All components are approved in pressure treated ACQ Lumber. FastenMaster ThruLoks are now available in Professional Lumberyards across the country.
