q Fig. 137: Standard U-bolt U-Bolts
q Fig. 137S*: Special U-bolt (non-standard)
Size Range: 1⁄2" through 36"
Material: Carbon steel U-bolt and four finished hex nuts
Finish:
(HDG not available for rod size 1/4". Stanless steel is offered as an alternative.)
Service: Recommended for support, or guide of heavy loads; often employed in power, process plant and
marine service.
Approvals: Complies with Federal Specification A-A-1192A (Type 24),
69 and MSS SP-58 (Type 24).
Ordering Fig. 137: Specify pipe size x rod size (e.g., 6 x
with longer tangents D or with longer threads E if so required and ordered. If hex nuts are not required,
specify “without hex nuts”.
Ordering Fig. 137S: Specify figure number, name, material specification, dimensions A, B, C, D, and E, and
“with hex nuts” or “without hex nuts”.
Note: The acceptability of galvanized coatings at temperatures above 450°F is at the discretion of the end user.

Loads, weights and dimensions shown do not apply for Fig. 137S. Max load rating for carbon steel is based on 2 x
load rating for rod. Max load rating for stainless steel is 0.85 times the maximum stated load ratings listed above.

*When the combination of a normal load and
a side load occurs, a straight line interaction
formula may be used to determine if the Fig. 137
is still within the allowable stress range:
Pn/Pna + Ps/Psa ≤ 1
Where:
Pn = actual applied normal load;
Pna = allowable normal load for the Fig. 137;
Ps = actual applied side load;
Psa = allowable side load for the Fig. 137
Nuts must be snug tight in installation to
achieve side loads shown.
