HOW TO SELECT YOUR PRODUCT . . .
TYPE A Point: A type of self-tapping screw for use in
thin metal. Used with drilled, punched or nested holes
in sheet metal, and other combinations of material.
TYPE F Point: A thread cutting screw with machine
screw thread with blunt tapered point, having multi -
cutting edges and chip cavities. For heavy gauge sheet
metal, aluminum, zinc and lead die castings, cast iron,
brass and plastic.
DOG Point: A straight pointed section reduced in diameter
slightly below the root diameter of the thread, usually
extending in length about two-thirds the diameter of
the thread. Recommended for ease in starting, to insure
against stripping ne threaded products.
TYPE AB Point: A self tapping screw combining the
locating point of Type A with the ner thread size and
pitch of Type B. Normal limitations of type B apply.
REAMER Point: For specialized applications specically
fastening wood to steel or aluminum. Self-drilling wings
will break o once it has reached contact with the steel.
1/2 DOG Point: The half dog point screw has a at tip
protruding from one end which is normally located into
a groove in a shaft and allows the shaft to rotate whilst
retaining the part in place.
TYPE 23 Point (Type T): A thread cutting screw in the
ne thread series oering maximum thread cutting area
and excellent chip clearing, with minimum tightening
torques.
FLAT Point: A at point screw has a at surface on one
end. This type of screw is used for frequent relocation of
parts where minimal shaft deformation is required.
BLUNT Point: A at tip point style found in most hex bolt
and machine screw products and designed to accept a
female threaded mating part.
TYPE 25 Point (Type BT): Similar to type 23 point except
with coarse Type B thread. For plastics and other soft
materials with large chip clearing and cutting edges.
CONE Point: Oers a smooth surface, accurate length,
and a sharp point which can be produced to any desired
contour to t your particular requirements.
TYPE B Point: A self tapping screw for use in heavier
metal. Larger root diameter with ner thread pitch
for light and heavy sheet metal non - ferrous castings,
plastics, impregnated plywood, and other materials.
SELF-DRILL Point: Self-Drilling Screws (TEK Screws), are
similar to sheet metal screws but with a “drill bit-style”
point that drills its own pilot hole. There are several points
styles including type 2, 3, 4 & 5 drill points depending on
thickness of material to be fastened together.
CHISEL Point: Point style with two 45 degree angles
at the tip of the stud or rod designed for mixing of
chemical components inside of a drilled hole, most often
for anchoring applications.
TYPE 17 Point: A thread cutting screw for wood with
a coarse tapping screw thread and a special long sharp
point uted to capture chips.
KNURL Point: Generally used to secure one object
within another. The serrated ridge on the knurl cup set
screw helps reduce loosening due to vibration.
TYPE 1 Point (Type D): A thread cutting screw with
single ute for general use. Produces a ne standard
machine screw thread for eld replacement.
CUP Point: A special cup section supplied on the end of
the threaded member having a depression in the end
to reduce the area in contact with the surface which
increases its holding and locking power under pressure.
TYPE BP Point: Same as Type B but has a cone point for
use where holes are slightly misaligned.
SELF-PIERCE Point: Produces more secure sheet metal
assemblies. This fastener can be used as self-drilling screw
or used to drive thru pre-punched holes or no holes in
light gauge sheet metal.
NAIL Point: Usually supplied with an approximate 45°
included angle having a sharp point and slightly squared
surface. Used for impinging or locking against wood or
other soft material.
