INDUSTRIES CORP.

By bending the wire around the sharp corner

of the terminal, the oxide layer on both wire

and terminal is crushed or sheared, and a clean,

oxide-free metal-to-metal contact is obtained.

A “Regular” bit wraps the bare wire around the terminal.

A “Modified” bit wraps a portion of insulation around

the terminal in addition to the bare wire.This

greatly increases the ability to withstand vibration.

OPEN WRAP & SPIRAL

WRAP

Just keep the OK tool on the

terminal until the wrap is

complete. Early removal can

result in spiral and open

wraps.

PIGTAIL

Wire wrapping is a precision

technique and the wrong bit and

sleeve just cannot do the job.

Improper selection can cause

problems ranging from “Pigtails”

to loose wraps.

Wire Wrapping is a method of making a wire connection by coiling the bare wire around the sharp corners of a

terminal under mechanical tension. The technology was developed as an alternative to soldering, which presents

various safety and reliability problems in many applications. A principal advantage of wire wrapping is that it

provides a high-reliability connection that is also easily removed to correct or modify a wiring layout. Wire wrapping

subjects the wire to tremendous tension and compression forces, causing the oxide layer on both wire and terminal

to be crushed or sheared, resulting in a clean, oxide-free metal-to-metal contact. A standard wrap is generally used

for 24 AWG and larger diameter wires; a modified wrap is typically used for 26 AWG and smaller wires, and is used

almost exclusively for 28 to 30 AWG wires. In either case, the wrap style affects only the connection’s mechanical

stability; both styles provide suitable electrical connections.

WIRE WRAPPING OVERVIEW

INSUFFICIENT TURNS

It’s easy to feed wire into the slot in

the OK bit correctly. Be sure the

stripped end of the wire is “pushed-

in” all the way.

OVERWRAP

Do not press too hard. Let the OK

tools do the work. Excessive

pressure can lead to overwrapping.

Backforce

"BF"

prevent

overwrapping is available on most

power tools and is recommended

for use with 26 through 30 AWG

wire.
