BaerFix® Instructions for use

1. Core drilling

first step: core hole drilling, cross sectional view

Use a core drill to ream the old hole.
If necessary, countersink the hole with a taper countersink.

2. BaerTurn fixed onto the installation tool

second step: turn thread insert onto installation tool, cross-section illustration

BaerScrew the fixed thread insert, with the cutting slots facing downwards, onto the installation tool and lock it with the nut. To do this, use an open-end wrench or similar.

3. BaerFix screw in

third step: screw in threaded bush, cross-section illustration

BaerFix into the bore hole. The BaerFix thread insert cuts its own mounting thread. The installation tool has a 1/4" hexagon socket (bit socket) and can therefore be screwed in with a cordless screwdriver, ratchet, nut or similar.

4. Loosen lock nut and unscrew installation tool

fourth step: Loosen lock nut and unscrew installation tool, illustration in cross section

Loosen the lock nut again with an open-end wrench and unscrew the installation tool. With BaerFix, the thread is now more wear-resistant, heavy-duty and vibration-proof than the original thread.
