What are Taptite screws?
TAPTITE® thread rolling screws roll form threads in plain cored, drilled, or punched holes upon assembly. Creating vibration resistant assemblies, eliminating the need to pre-tap internal threads in ductile materials such as steel, aluminum, zinc, etc., thus lowering the cost of assembly.
Are Taptite screws self tapping?
Taptite self tapping screws, also known as triangular thread tapping lock screws, it is a kind of self tapping screw, at the same time, it has the function of tapping and locking.
What are Trilobular screws?
TAPTITE II® thread-rolling screws have the TRILOBULAR® shape, which reduces friction during thread forming, provides prevailing torque, which exceeds the level of locking screws, and most importantly, inherently provides resistance to vibrational loosening.
What are Plastite screws?
PLASTITE® TRILOBULAR™ thread- rolling screws were developed specifically for use in plastics. They combine a unique TRILOBULAR™ cross-sectional form with deep, wide, spaced threads. Easier to drive. Three swaging lobes with full relief of the thread form reduce driving effort and operator fatigue.
What are pan head screws?
Pan head screws are a common head type of non-countersunk screw head used in wood screws, self-tapping screws, self-drilling screws, and machine screws. They have wide heads, a flat bearing surface, high vertical, chamfered, or curved sides, and a flat or slightly domed top surface with a recessed socket.
What is a thread rolling screw?
Thread rolling screws are designed for reliable and secure fastening into materials such as plastic. They have a trilobular lobed cross-section, and form threads in pre-existing holes by pushing material outward during installation.

What is Plastite?
PLASTITE® TRILOBULAR® thread-rolling screws were developed specifically for use in plastics. They combine a unique TRILOBULAR® cross-sectional form with deep, wide, spaced threads.
What is a PT screw?
PT screws have a narrow 30° thread profile which minimizes radial expansion and stress in the boss. This allows for the use of thinner bosses, which can reduce cycling times and material usage. It also reduces back-out caused by relaxation, and can increase load-carrying capability through increased thread engagement.
What screws to use for plastic?
Use round- or oval-headed wood screws to screw rigid plastic and avoid sinking the heads by countersinking. A countersink, which is a hole deep enough for the head to sink to surface-level, weakens the plastic and may cause it to break.
