Flex OlyLok Locking Impact Nail User Manual
COMPOSITION
Factory preassembled components consisting of:
Tube:
Precision formed from Galvanized (G-90) coated steel to prevent corrosion.
The tube is shaped to easily penetrate decking and existing membranes.
Disk: Precision formed from Galvalume (AZ-55) coated steel to prevent corrosion.
Securely clamped to the tube, 2.7" diameter, rib reinforced to resist cupping.
Locking Staple: Precision formed from high tensile steel wire.
Coated to prevent corrosion.
TECHNICAL DATA
Fastening Pattern: Consult Flex for requirements for recommended patterns
in normal, exposed, and hurricane areas.
Field Testing: On-site withdrawal testing should always be performed to
evaluate the ability of the roofing substrate to satisfactorily accept and retain
fasteners. Such testing may alter fastener selection and modify applicable
fastening patterns.
The OlyLok should always be embedded into the structural roof deck to a
depth of at least 1".
INSTALLATION
Installation Tools: There are two tools that must be used to install the OlyLok
Locking Impact Nail. The OlyLok Driver is for installing base sheet and recovery
board to the substrate. For securing ISO or EPS to the substrate use the OlyLok
Insulation Tool, which has a larger impact area. Consult Flex for the specific
driver for your application.
Method: Drive fastener perpendicular to roof deck seating cap flush with roofing
surface. Once tube is set, drive the locking staple thru the tube/disk unit into the
deck until the top of the staple is flush with the cap (see illustration).
Operation: When locking staple is driven, its dual wire legs diverge anchoring
the fastener in place (see illustration). Uplift resistance may vary depending on
the density and integrity of the substrate.
Packaging: 1.4", 1.8", 2.8", and 3.8" OlyLoks packaged 500 per carton.
4.8" OlyLoks packaged 250 per carton.

For Attaching Base Ply, Recovery Board and
Insulation to Wood Fiber/Poured Gypsum Decks
Fastener density and spacing vary depending on applicable uplift require-
ments. Local codes, governing approval bodies, membrane manufactur-
ers, and individual roofdeck manufacturers all may have specific require-
ments that need to be addressed prior to beginning any roofing project.
The OlyLok should always be embedded into the structural roof
deck to a depth of at least 1". The following illustrates typical Factory
Mutual recommended fastening patterns widely accepted by membrane
and roofdeck manufacturers.
