- CEE Thread Enlarges Hole for Improved Drawing Strength

Patented washer type head, with a reinforced shouder underneath, produces extreme pressure pulling the log down, eliminating the need to add a washer as required for common lag screws. Head can be countersunk 1"-3" without pre-drilling a countersink hole. Case hardened steel Climatek™ coating, ACQ Approved. Lifetime limited warranty.

Exclusive CEE thread slightly enlarges hole for screw shank and allows log to settle without restriction. Eliminates pre-drilling as required for the common lag screw. Complete and effective installation in one operation.  The 4 inches of deep rolled threads are very sharp, as they provide extreme pulling and withdrawal power.  Patented W-Cut™ Slices a groove for next thread, reducing tension and pressure on fastener, providing ease of installation and the  Zip-Tip™ is excellent for quick and easy starting.
