Cyclone® TEKS® Self-Drilling
Fasteners
Cyclone
Teks combines a self-drilling point and an undercut head
with a serrated helical shoulder to absorb high driving
torque, making it the complete fastener for sheet metal
ranging in thickness from .015" to .110".
The unique combination of metal drilling and torque absorption
provides a greatly increased safe operating range between
drive and strip torques.
GER-NIB® FEATURE:
For particularly torque-sensitive applications, Shakeproof's
torque-robbing Ger-Nib feature can be incorporated in
the Cyclone Teks head.

Tests
involved 8-18 x 1/2 and 10-16 x 1/2 Hex Washer Head fasteners,
with a .0002 zinc, clear chromate and wax finish, driven
into a .020" and .030 SAE 1010 steel bearing plates
and tapping plates (RB 45 hardness). Where used in bearing
plates, clearance holes for number 8 Teks fasteners were
.196" diameter, and for the number 10, were .220" diameter.

SELECTION
GUIDE
Different
diameters and types of Teks fasteners incorporate specific
drill point lengths and designs that are capable of drilling
a wide range of metal thicknesses. In the table below,
the drilling capabilities of the Teks/2 point Teks and
the Teks/3 point are provided as a guide.
