Thread Code Chart No. 3

Thread code is the 4 digit number assigned to the part number to designate
the thread size of a part. All threads are Class 2 (A and B) (commercial)*.

*Note: For special threads, contact Amatom Sales Office for Number.

Self Locking Hardware (No lockwashers required)

Amatom threaded hardware is available with HELI-COIL® inserts.
(HELI-COIL® inserts not available in Teflon and Delrin parts.)

To specify parts requiring a HELI-COIL® locking insert - add the letters “HL”
to the thread code, i.e. 80 XX - B - 0440HL

Unless otherwise specified HELI-COIL® inserts will be 1 1/2 x diam. of the
thread.

(Prices available on application only.)

Manufacturing Notes

Special

Alert

Externally

threaded products

made from

Brass or Steel

i.e. Male/female standoffs

or captive screws

The external threads are manufactured to a
pre-plated condition to accommodate the
plating process. Unplated parts will accept the
standard no-go gauge.

On a special order basis, Amatom will
manufacture these products for applications
that do not require plating, and will not be
made to a pre-plated condition.

Specifications

Anti-Rotation Swage Standoffs

3-4 times more holding power than conventional standoffs. The Amatom high torque (anti-rotation)
swage standoff is designed primarily for installation in epoxy glass, phenolic boards and aluminum
panels or chassis. This broaching type standoff literally cuts its way down into the mounting
material, biting in for torque resistance. The knurled shank feature eliminates electrical connection
breaks due to loosening and spinning of the standoff under high torque conditions.
