What it is

The Fervi E011/BSF1/4M is an STI tap for British BSF 1/4" x 26 threads: it is the special tap that cuts in the workpiece the seat for the F-coil wire thread insert, not the final thread. It is 72 mm long, with 22 mm of threaded length, has a B dimension of 7.5 mm, an 8 mm shank and a 6.3 mm square for the tap wrench. Fervi's BSF series runs from 3/16" to 1".

These are tools and kits for repairing damaged threads: a larger threaded hole is made and a helical spring insert is screwed into it, restoring the original thread.

What it is for

Used in workshop machining of steel, aluminium and alloy parts, in mechanical maintenance of machinery and plant, during scheduled shutdowns or breakdowns and for workshop and on-site repairs.

How to use it

Drill out the damaged hole with the drill bit indicated by the kit, cut the new thread with the dedicated tap and screw in the insert with the installation tool to the specified depth. If applicable, remove the tang. Then screw the bolt into the restored thread. To remove an insert, use the extractor.
