Thread Repair Tap

The HELI-COIL 3FPB is a straight-flute hand tap designed to cut internal threads for screw-thread inserts. It suits mechanics and technicians who repair stripped or damaged holes in automotive and general maintenance work.

Sustained Cutting Performance

High-speed steel construction resists wear during repeated threading operations. The uncoated bright finish reduces galling in softer materials while the plug chamfer starts threads cleanly through the full depth.

#10-32 UNF Thread Size

This tap cuts a #10-32 UNF thread with an H2 limit using three flutes over a one-inch thread length. It is not for creating standard fastener threads or for use with thread sizes other than #10-32.

Questions about this item

Does the #10-32 plug tap generate much heat or noise during extended hand use?

As a manual cutting tool it produces no motor noise and negligible heat; only light friction warmth occurs while tapping.

What handle or wrench do I need to turn this 3-flute tap?

A standard tap wrench sized for a #10 tap is required; the tool has no built-in drive.

Will the H2 thread limit on this tap match the #10-32 UNF holes in my older fixture?

The H2 limit is the standard fit for #10-32 UNF, so it will cut threads compatible with existing hardware.
