What is a Taptite thread?
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.
What is Trilobular thread?
Trilobular Thread Forming System. The nut threads are automatically formed in cast blind holes, passages or in drilled, lasered or punched sheet metal parts. Especially suitable for materials such as steel, aluminium, brass or copper. A trilobular thread forming screw forms a thread with a machine screw’s thread pitch.
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.
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.
How do Taptite screws work?
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 pan head screws?
A pan head self-drilling screw has a rounded base and a flat head that sits on top of the material it fastens. With its large diameter and high edges, the drive slot is deep, which allows for increased torque while minimizing the risk of damage to the screw.
Who makes Plastite screws?
Plastite® 45 Screws | STANLEY® Engineered Fastening.
Is thread forming and thread rolling the same?
Thread forming and thread rolling, while both involving the creation of threading, aren’t the same. The primary difference between them is that thread forming is used to create internal threading, whereas thread rolling is used to create external threading.
What does a Panhead screw look like?
Pan head screws take their name from the appearance of their head, which looks similar to an upside-down frying pan. 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.
What are screw sizes?
Screw Sizes For screws measured in inches, diameters of 1/4 inch and smaller (for machine and sheet metal screws) or 5/16 inch and smaller (for wood screws) are expressed with a # and a whole number (ex., a screw with a major diameter of 3/16 inch is a #10 screw). Smaller numbers indicate smaller diameters.
What is the pitch of a thread with 16 threads per inch?
