Flange Bolts
The 3051S can be shipped with a Coplanar flange or a Traditional flange
installed with four 1.75-inch flange bolts. Mounting bolts and bolting
configurations for the Coplanar and Traditional flanges can be found on
page 2-6, 7. Stainless steel bolts supplied by Emerson Process Management
are coated with a lubricant to ease installation. Carbon steel bolts do not
require lubrication. No additional lubricant should be applied when installing
either type of bolt. Bolts supplied by Emerson Process Management are
identified by their head markings:

Bolt Installation
Only use bolts supplied with the Rosemount 3051S or sold by Emerson
Process Management as spare parts. When installing the transmitter to
one of the optional mounting brackets, torque the bolts to 125 in-lb.
(0,9 N-m). Use the following bolt installation procedure:
1. Finger-tighten the bolts.
2. Torque the bolts to the initial torque value using a crossing pattern.
3. Torque the bolts to the final torque value using the same
crossing pattern.
Torque values for the flange and manifold adapter bolts are as follows:
