LL LumberLok Exterior Structural Connector Screws
LL915
The LumberLok Exterior Structural Connector Screw is a
self-drilling screw that can be used with a number of MiTek
connectors and also for wood-to-wood applications. The screws
feature a T20* drive head with integral washer and gimlet point for
ease of installation. The twin-lead threads drive in twice as fast as
the single lead threads signicantly reducing installation time. The
USP head stamp identies the screw length for easy inspection.
Screw shear capacities are based on a diameter of 0.162" when the
shear plane is on the screw shank (SH) and 0.109" when the shear
plane is on the threads (T). MiTek LumberLok Exterior Structural
Connector Screws have a bending yield strength of 170,000 psi.
Materials: Low carbon hardened steel.
Finish: Gold Coat
Codes: IBC, FL, LA
Installation:
• Screws are self-drilling.
• Install using a low speed clutch drill with T20* drive (not included).
The washer head should be at to the surface. Do not over-tighten
the screws.
• Installing the screw at an angle may introduce additional bending
and tension forces into the fastener if the screw head is not at to
the bearing surface. Care should be given to ensure the fastener
is installed perpendicular to the plane of the fastener hole.
• Impact drills are not recommended for use with
LumberLok Screws

screws on page 37.
