Thread Terminology
A. FULL DIAMETER SHANK:
Equal to major diameter of thread. Produced by cut thread or by roll thread on extruded blank. Characteristic of machine
bolts and cap screws.
B. UNDERSIZED SHANK:
Equal approximately to pitch diameter of thread. Produced by roll threading a non-extruded blank. Characteristic of
machine screws.
C. PITCH:
The distance from a point on the screw thread to a corresponding point on the next thread measured parallel on the axis.
D. MAJOR DIAMETER: The largest diameter of a screw thread.
E. PITCH DIAMETER: The simple, effective diameter of screw thread. Approximately half way between the major and
minor diameters.
F. MINOR DIAMETER: The smallest diameter of a screw thread.
LEAD: The distance a screw thread advances axially in one turn.
CUT THREAD: Threads are cut or chased; the unthreaded portion of shank will be equal to major diameter of thread.
ROLLED THREAD: Threads are cold formed by squeezing the blank between reciprocating serrated dies. This acts to
increase the major diameter of the thread over and above the diameter of unthreaded shank (if any), unless an extruded
blank is used.
Classes of thread are distinguished from each other by the amounts of tolerance and allowance specified. External threads
or bolts are designated with the suffix "A"; internal or nut threads with "B".
CLASSES 1A and 1B: For work of rough commercial quality where loose fit for spin-on-assembly is desirable.
CLASSES 2A and 2B: The recognized standard for normal production of the great bulk of commercial bolts, nuts and
screws.
CLASSES 3A and 3B: Used where a closed fit between mating parts for high quality work is required.
CLASS 4: A theoretical rather than practical class, now obsolete.
CLASS 5: For a wrench fit. Used principally for studs and their mating tapped holes. A force fit requiring the application of
high torque for semi-permanent assembly.

TYPES OF BOLT AND SCREW HEADS
PAN HEAD: Recommended for new designs to replace
round, truss and binding heads. Provides a low large
diameter head, but with characteristically high outer edge
along the outer periphery of the head where drive action is
most effective for high tightening torques. Slightly
different head contour where supplied with recessed head.
See dotted line.
ROUND HEAD: Not recommended for new design (see pan
head). This head was the most universally used design in
the past.
FILLISTER HEAD: The standard oval fillister head has a
smaller diameter than the round head, but is higher with a
correspondingly deeper slot. The small diameter head
increases the pressure applied on the smaller area and can
be assembled close to flanges and raised surfaces
BINDING HEAD (Straight Side): Most generally used in
electrical and radio work because of its identifying
undercut beneath the head, which binds and eliminates
fraying of stranded wire. A medium - low head with
ordinarily sufficient bearing surface. Not recommended as
a Phillips Recessed head – see Pan Head for better
functional design.
TRUSS HEAD: Also known as oven head, stove head, and
oval binding head. A low, large diameter head that can be
used to cover larger diameter clearance holes in sheet
metal when additional play in assembly tolerance is
required.
ONE-WAY HEAD: This tamper-proof type of head, once
assembled cannot be removed, yet is driven with a
standard screwdriver.
FLAT AND OVAL HEADS (UNDERCUT): The standard flat or
oval head 80° to 82° counter sunk screw will fit a standard
counterbored hole and is particularly adaptable to flush
assemblies in thin stock.
SQUARE SHOULDER SCREWS: An adaptation of the
standard carriage bolt design. Possesses a truss head on a
square shank, which resists rotation when located or
driven into place.
Page 82 of 99
Page 82 of 99
INDENTED HEXAGON: A wrench head fastener made to
standard hexagon head dimensions. The hex possesses an
identifying depression in the top surface of the head.
INDENTED HEXAGON WASHER HEAD: The same as the
standard indented hexagon head but with a washer section
at the base of the head to protect the finish of the
assembly from wrench disfigurement, and to economically
replace a separate bolt & washer assembly.
HEXAGON HEAD (TRIMMED): This is the standard type of
wrench-applied hexagon head, characterized by clean,
sharp corners trimmed to close tolerances. Recommended
for general commercial applications.
HEX FLANGE: Similar to hex washer with the exception that
the top of the washer-flange shall be conical or slightly
rounded within the periphery of the flange diameter. The
coutour of the flange edges shall be optional provided
minimum flange thickness is maintained.

SCREW POINT TYPES
Wood Screw
Wood screws taper gradually from the head to the point. Some wood
screws are only partially threaded (depending on the length).
Tapping Screws (Type A, AB, B)
Type A point: A thread forming screw for use in thin metal .015 to .050
thick. Used with drilled, punched or nested holes in sheet metal, resin
impregnated plywood, asbestos combinations, among others. Not
recommended for new design.
Type AB point: A thread forming screw combining locating point of Type
A with thread size and pitch of Type B. Normal limitations of type B apply.
Type B point: A thread forming screw for use in heavier metal .050 to .200
thick. Larger root diameter with finer thread pitch for light and heavy sheet
metal non - ferrous castings, plastics, impregnated plywoods, asbestos
combinations, and other materials.
Thread Cutting Screws (Type 1, 17, 23, 25, F)
Type 1 point: A thread cutting screw with single flute for general use.
Produces a fine standard machine screw thread for field replacement.
Type 17 point: A thread cutting screw for wood with a coarse tapping
screw thread and a special long sharp point fluted to capture chips.
Type 23 point: A thread cutting screw in the fine thread series offering
maximum thread cutting area and excellent chip clearing, with minimum
tightening torques.
Type 25 point: A thread cutting screw similar to type 23 point except with
coarse Type B thread. For plastics and other soft materials with large
chip clearing and cutting edges.
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, alu - minum, zinc and lead die castings, cast
iron, brass and plastic.

Thread Forming Screws (Type C, CA, Tri-Round, Lo-Driv)
Screws for Plastic (Tri-Round, Round)
Type C point: A thread forming screw with either coarse or fine pitch
machine screw thread and blunt tapered point. Eliminates chips and
permits replacement with standard screw in the field. Higher driving
torque required. Usable in heavy sheet metal and diecastings.
Type CA point: A thread forming screw with either coarse or fine pitch
machine screw thread. Same as Type C except with a Gimlet point. The
locating point works better than Type C where holes between two
adjoining pieces of sheet metal may be somewhat misaligned.
Tri-Round: A thread forming screw in mostly coarse machine screw
threads. Three vertexes perform a roll - forming process to form mating
threads. Much better thread forming than Type C or CA, and drives with
less torque.
Lo-Driv: A thread forming screw in mostly coarse machine screw
threads. The point and body design requires low end - load for starting
and low drive torque for seating. The full 360 degree body above the
point provides excellent strip-to-drive ratios.
