DRILL SCREWS 

Special shoulder keeps screw 

from “over-clamping” the rake 

support, allowing for thermal 

expansion. 

RAKE ANGLE ATTACHMENT 

Proprietary standoff screw designed to allow 

thermal expansion of the rake support angle 

We designed a BLAZER ® Drill Screw specifically for attaching 

a sliding rake plate used in metal roofi ng. 

The screw has an oversize washer face that provides more 

bearing surface between the fastener and the rake plate angle 

that allows superior movement capabilities. 

TYPICAL APPLICATION 

5/16” hex drive is the same size as 

other standard metal roofi ng fasteners 

for easy installation. 

Oversize washer face provides over 

45% more surface area that is in 

contact with the rake support!

Need to attach wood to thin gauge metal? 

Then use our #12-14 BLAZER ® Header Light Gauge that is designed 

to fasten to metal as thin as 18-gauge! The threads and wings are 

engineered for optimal performance when used in thin metal applications. 

Need to attach wood to steel that is 1/2” thick? 

Then use our new 1/4-20 BLAZER ® Header Heavy Gauge (1/2” SD), 

the only wood-to-metal fastener that will drill and tap steel up to 1/2” 

thick. Engineered for use in heavy steel, it has a special hex-countersunk 

head that provides optimal driving stability and can also be installed 

flush to the surface of the wood. 

Both fasteners have “wings” that remove the wood to minimize jacking 

and provide drilling consistency.

Our Vibration Resistant Thread (VRT ® ) is 

designed to significantly increase back-out 

torque and reduce the potential for leaks. 

VRT ® keeps the fastener tighter in 

applications where expansion, contraction 

and vibration are a concern. 

Independent tests verify that VRT ® 

produces 3-1/2 times more back-out 

resistance than a standard thread.

Pat. No. 8,360,701 

The next generation of self-drilling screws specifically designed to resist back-out 

which can cause leaks in metal panel laps and joints. 

PROBLEM 

Screws with standard threads can back-out 

easily with little force. This can cause joint 

failure resulting in leaks. 

SOLUTION 

Our Vibration Resistant Thread (VRT) is 

designed to signifi cantly increase back-out torque 

and reduce the potential for leaks. 

Notice how standard 

screw threads offer little 

resistance to back-out. 

Innovative patent pending 

VRT thread increases friction 

as the screw loosens. 

Why VRT ? 

You can see how the shape of 

VRT is designed to increase the 

resistance to back-out, compared 

to a standard thread. VRT 

keeps the fastener tighter in 

applications where expansion, 

contraction and vibration 

are a concern.

Chart was revised by TFC based on various panel manufacturer's specifications and actual job-site performace. 

Note 1: Cautionary Guideline: This table serves as a guideline for the selection of fasteners used with metal roofing. The performance 

of compatible fasteners shown in this table matches the expected life of the metal roof or wall cladding materials. However, in highly 

corrosive environments such as heavy industrial, coastal marine, high airborne pollutants or salt spray, preservative treated lumber or 

fire-retardant lumber, the compatibility of certain fasteners with metal roofing or wall cladding materials may be affected. In those types of 

applications, the manufacturers of the fastener and metal panel will have specific and unique recommendations. 

In addition, in the event that certain coating barriers are damaged or scratched through to the substrate there is increased potential for 

premature corrosion. Care should be taken during installation and during routine maintenance of the panels in order to protect the integrity 

of the coatings used for metal panels. 

Note 2: Screws should be plated/coated per ASTM F1941 

Note 3: Nails should be galvanized per ASTM A153 

Note 4: Not recommended for coastal and heavy industrial environments 

Special Note: Preservative-Treated Lumber Applications 

ACQ, Penta, CA or CBA preservative-treated lumber can be incompatible with certain types of fasteners. In those cases where any type 

of metal roof or wall cladding materials are being attached to preservative treated lumber, the following fasteners are not compatible: zinc 

plated screws, zinc-alloy headed screws, stainless capped screws, aluminum, copper and copper alloy. When attaching metal panels to 

those types of preservative-treated lumber, a moisture barrier should be used between the lumber and the panel material. Metal panel 

fasteners that are compatible with preservative-treated lumber are stainless steel fasteners, or hot dip galvanized nails manufactured 

to ASTM A153 class D or heavier. Other types of fasteners coated with proprietary anti-corrosive technologies are also available for use 

with preservative-treated lumber. In addition, zinc-plated screws can be used in CCA and MCQ pressure-treated lumber.

SEM IMAGING 


TRI-SEAL LONG-LIFE COATING 

TRI-SEAL Long-Life Coating is a high performance dip spin fi nish, 

developed to minimize corrosion when used in exterior building applications. It 

consists of three layers; the fi rst layer is a metallic zinc layer, the second layer 

is a high-grade anti-corrosion chemical conversion fi lm and the third, outer 

layer, is a baked ceramic surface coating. 

The distinguishing feature of TRI-SEAL is the tight joining of the baked 

ceramic surface coating and the chemical conversion fi lm. These two layers 

are bonded together through chemical reactions, and this unique method of 

combining layers result in a rigid combination of the coating fi lms. 

■ Excellent resistance against gas, weather, and other kinds 

of corrosion factors, including salt water. 

■ Compatible for use in ACQ and Fire Treated Lumber. 

■ Composite layers minimize the effect of scratches on the 

protection coating. 

■ Compatible for use in aluminum applications. 

Layer 1 - Baked Ceramic Surface Coating Layer 

Corrosive elements are intercepted by the 

strong paint fi lm made of ceramic materials. 

Layer 2 - Chemical Conversion Coating Layer 

Rust proof performance is improved as the 

chemical conversion inactivates the zinc plated 

surface and creates a tight adhesion between 

the chemically converted layer and the 

paint layer. 


Layer 3 - Metallic Zinc Layer 

The steel / iron substrate is protected from 

corrosion by the self-sacrifi cial galvanic effect 

of the zinc coating. 

Layer 4 - Fastener

#14 DP1 CONCEALOR ® with 

TRI-SEAL coating provides 

the best corrosion protection in 

the industry! Salt spray tests 

confirm that TRI-SEAL 

coating provides over 10 times 

more resistance to red rust than 

black epoxy coated screws. It is 

engineered to perform in a 

variety of applications. 

FM approved for preliminary 

attachment of nail base 

insulation without the use of 

stress plates. 

Here is why we use a special thread... 

We use a buttress thread form that provides 

exceptional clamping loads. It is specified in 

many metal roofing systems to attached SSR 

clips over rigid insulation into metal deck.

Fastening Tips 

• A minimum of three (3) factors of safety should be used for most self-drilling or self-tapping 

fasteners. Consult a design professional for appropriate values. 

• Install fastener perpendicular to the work surface and tighten to no more than 

approximately 70% of the torsional strength. 

• Allow at least three full threads to extend beyond the material. For wood applications, 

allow 1” minimum embedment or full thread embedment in plywood and OSB for optimal 

pullout resistance.
