This is the insert that permanently protects threads against wear, stripping, corrosion, galling, seizing, vibration and shock. 

Made of (18-8) Austenitic Stainless Steel wire, cold rolled into a diamond shaped cross-section, this FASTMAN Insert conforms to standard commercial and industrial thread forms

This FASTMAN Screw-Lock one-piece insert provides all the thread protection of the Standard (Free Running) Thread Insert, PLUS an exclusive internal locking feature that eliminates the need of clumsy protruding lock-nuts, lock-wiring and other supplementary locking devices. 

NAG FASTMAN (High Speed Steel) Taps are available in three different styles which can be used individually or in combinations depending on the application.

Roughing Taps
Provides full diameter thread and has 5 taper leads.

Finishing (Plug) Taps
Provides full diameter thread and has 3½ taper leads. Finishing taps are the most commonly used taps for tapping through holes.

Bottoming Taps
Provides full diameter thread to the bottom of blind holes since tap has only 1½ lead threads.

FASTMAN Thread Plug Gauges are used to check the accuracy of the tapped hole produced by FASTMAN Taps. Since the final fitment of the FASTMAN Insert is highly dependant on the tapped hole, a FASTMAN Gauge ensures and checks the tapped hole accuracy before a FASTMAN Insert is fitted.

Prewinder Inserting Tools are used for FASTMAN Screw Thread Insert installation. These inserting tools are suitable for both Standard (free running) and Screw Lock Inserts.

These are used for breaking-off the tang in a Screw Thread Insert after installation of the same in a tapped hole.This is easily accomplished by placing the punch of the Tang Break-off Tool into the installed insert and resting tool squarely on the insert tang. Striking the top of the tool with a hammer, using a sharp blow breaks off the tang.

In rare instances, inserts are installed too deep, cross-threaded or otherwise improperly inserted. Such inserts are readily removed with FASTMAN Extracting Tools which are available in four sizes to fit all sizes of inserts.
