NOTES:

1. EXISTING BOLTS, STUDS OR THREADED HOLES MAY BE USED FOR BOND STRAP INSTALLATION.

2. THE INSTALLATION PROCEDURE FOR BOLTED STRAPS PROVIDES FOR CLEAN BRIGHT METAL CONTACT BETWEEN THE BOND STRAP AND THE

MATING SURFACE.

3. STUDS USED FOR BOND STRAP ATTACHMENT SHALL BE A COLLAR TYPE. TO PERMIT WELDING, STUD MATERIAL SHALL CORRESPOND TO THE MATING SURFACE MATERIAL; ALUMINUM STUDS FOR ATTACHMENT TO ALUMINUM SURFACES AND STEEL STUDS FOR ATTACHMENT TO STEEL SURFACES.

4. BOLTED BOND STRAP CONNECTIONS SHALL BE WEATHERPROOFED.

OR THREADED HOLE

5. FOR SHIPBOARD EXTERIOR APPLICATIONS, ITEMS 2, 3, 4 AND 5

SHALL BE OF CORROSION RESISTANT STEEL (CRES 316).

6. THE BOSS OF TYPE I BOND STRAPS MAY BE BOLTED IN PLACE ON EQUIPMENT WHERE WELDING CANNOT BE ACCOMPLISHED. BOLT LENGTH IS CRITICAL. USE THE BOLT SUPPLIED WITH THE BOSS.

THE BOLT SHALL NOT CONTACT THE BOTTOM OF THE BOSS THREADED

SOCKET.
