FOR STANDARD PANEL AND COMPONENT THICKNESSES
Rolling Screws - With its graduated thread rolling
area, less driving torque is required to install the
Tap/R chip-free thread forming screw. Its full 360° thread
engagement provides maximum holding power and increases
stripping torque. Small pilot point minimizes cross
threading and facilitates hole alignment.
Taptite® II Thread Rolling Screws - Shakeproof offers
a complete line of "tri-lobular" thread rolling
screws. These chip-free thread forming screws have a
high strip-to-drive ratio.
Cutting Screws - There is a complete family of screws
designed to cleanly cut mating threads in metal and plastic.
In addition to the Shakeproof Types 1, 23, 25 and 17,
Types F and BF are available.
FOR PLASTICS AND OTHER LOW DENSITY MATERIALS
- these fasteners have a double lead high and low thread
form that increases performance in a broad range of
low density materials such as plastic, wood masonite
and particle board. The high thread has a 30° included
angle that is sharper than a conventional thread. This
reduces splitting and boss breakage, provides better
drive/strip ratios and holds securely.
|Hi-Lo® Plus TM Fasteners
- Both the high and low threads on this screw incorporate
the 30º included angle with a 45º angle step
on the trailing flank of the threads. These sharp threads
displace minimal material to reduce stress and cracking
and further increase drive/strip ratios. Heads on Hi-Lo
Plus fasteners are to ASTM/ANSI standard dimensions.
Hi-Lo® Plus TM Fasteners
- Drive/Strip Torque Relationships
- These trilobular thread rolling screws are designed
for high performance fastening in a wide range of thermoplastics.
As threads are formed, the plastic material recovers
and fills in around the trilobular threads, assuring
a secure assembly.
