The TRIFORM, TAPTITE II ® , DUO-TAPTITE ® and TAPTITE 2000 ® thread-forming screws
are designed for direct fastening in metals. The TRIFORM screw is characterized by
low thread-forming torque and good thread proof load at low production cost. The
TAPTITE ® screws have been specifically developed to meet extreme requirements for
assembly performance and proof load.
sheeT meTal
The TRIFORM DB is suitable for all applications with less extreme requirements for
assembly performance. EXTRUDE-TITE ® screws are characterized by a very low inser-
tion torque due to their geometry. The TRIFORM DB HF screw has been developed
specially for increased requirements in high-strength sheet metals with a strength
of up to 950 MPa and in stainless sheet steel.
magnesium
The use of high-strength RIBE ® ALUFORM ® aluminum screws is the optimum solution
for reliable fastening of magnesium components. Prestressing force losses through
additional thermally induced stresses are minimized by the very similar coefficients
of thermal expansion and contact corrosion is avoided almost completely even with
uncoated screws. The thread-forming version of these screws now also permits direct
fastening of sufficiently ductile magnesium alloys.
PlasTic
RIBE ® PR and PLASTOFORM screws are equally suitable for use in plastics. RIBE ® PR
is characterized by low-cost manufacture, whereas PLASTOFORM screws provide
high pullout forces due to their flow-optimized geometry and are also suitable for
brittle plastics.
