ANSI F1554 Anchor Bolt Highway Sign Carbon Steel Bolt
Specification
Anchor rods, also referred to as anchor bolts, concrete embeds, or
foundation bolts, are embedded in concrete foundations to support
structural steel columns, light poles, traffic signals, highway
sign structures, industrial equipment, and many other applications.
Manufacturing
QBH company has the ability to manufacture anchor rods from 1/2″ –
4″ diameter. Anchor rod assemblies are available in a number of
ASTM specifications including: F1554 grade 36, 55 & 105, A449, A354 and many others. Anchor plates, pipe sleeves, light fabrication and welding are
all performed on site to provide fast delivery at the highest
quality. Rods are provided either plain steel or hot-dip
galvanized.
Anchor plates, both square or rectangle, are produced on-site. Our
ability to punch and shear up to 3/4″ plate allows us to meet your
special requirements and provide solutions to reduce the overall
material cost.
F1554 SPECIFICATION
The ASTM F1554 specification was introduced in 1994 and covers
anchor bolts designed to anchor structural supports to concrete
foundations. F1554 anchor bolts can take the form of either headed
bolts, straight rods, or bent anchor bolts. The three grades 36,
55, and 105 designate the minimum yield strength (ksi) of the
anchor bolt. The bolts can be either cut or roll threaded and a
weldable grade 55 can be substituted for grade 36 at the supplier’s
option. Color coding on the end – 36 blue, 55 yellow, and 105 red –
helps facilitate easy identification in the field. Permanent
manufacturer and grade marking is allowed under the S2
supplementary requirements.
Applications for F1554 anchor bolts include columns in structural
steel framed buildings, traffic signal and street lighting poles,
and overhead highway sign structures to name just a few.
F1554 Grades
| F1554 Grade 36 | Low carbon, 36 ksi yield steel anchor bolts |
|---|
| F1554 Grade 55 | High strength, low alloy, 55 ksi yield steel anchor bolts |
|---|
| F1554 Grade 105 | Alloy, heat treated, high strength 105 ksi yield steel anchor bolts |
|---|
Supplementary Testing
Supplementary requirements shall apply only when specified in the
purchase order or contract.
S1: Weldable version of the Grade 55 specification. Through chemical
composition restrictions and by a carbon equivalency formula, S1
provides assurance of weldability. When S1 is not specified, the
Grade 55 material may or may not be weldable.
S2: Permanent manufacturer’s identification on the end of the anchor
bolt that projects from the concrete, in lieu of color-coding.
S3: Permanent grade identification on the end of the anchor bolt that
projects from the concrete, in lieu of color-coding.
S4: Charpy Impact requirements at +40⁰F (+5⁰C) for grades 55 and 105.
The minimum Charpy V-notch energy requirement is an average of
15ft-lbs for three specimens, with no one specimen falling below
12ft-lbs. Charpy Impact requirements at -20⁰F (-29⁰C) for grade
105. The minimum Charpy V-notch energy requirement is an average of
15ft-lbs for three specimens, with no one specimen falling below
12ft-lbs.

- Stamping of F1554 bolts with manufacturer's identification is a
supplemental requirement (S2)
- Color coding is required unless the grade is stamped in accordance
with supplemental requirement (S3).
- When Grade 36 is specified, a weldable Grade 55 may be furnished at
the supplier's option.

1 A563 grade D nuts are rarely available. A563 grade DH or A194
grade 2H should be substituted.
2 The availability of A563 grade DH nuts in nominal sizes 1″ and
larger is very limited and generally available only on special
orders of 50,000 or more. For smaller quantities, ASTM A194 grade
2H should be considered. |
