F1554 Grade 105 Anchor Bolts
ASTM F1554 Grade 105 quenched-and-tempered alloy steel anchor bolts — 105 ksi minimum yield, 125–150 ksi tensile, in diameters from 1/4" to 3".
Last updated: 2026-11
Specifications
Grade 105 is the top of the F1554 range: a medium-carbon alloy steel, quenched and tempered to 105 ksi minimum yield and 125–150 ksi tensile, reserved for high-demand connections — seismic retrofits, bridge and highway structures, tower and heavy-equipment anchorage. Diameter range runs to 3", and the heat-treated material means coating choices should be raised at quotation so hydrogen-embrittlement exposure is managed on hardened parts.

Ordering & documentation
Documents
Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.
Quotation
- The fastener family (F1554 Grade 105 Anchor Bolts) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
- Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
- Quantity per size and your target delivery date.
- Destination country, and any required documents (for example a mill test certificate) so the quote includes them.
Sample & supply
Minimum order quantity is 500–1,000 pieces. Standard production run 15–30 days. Quantities or variants outside the standard range are confirmed at quotation.
Storage & shipping
Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.
Frequently asked questions
Where is Grade 105 required instead of Grade 55?
Grade 105 is specified where connection demand exceeds the 55 ksi class — typical of bridge and highway infrastructure, seismic-design connections and heavy industrial equipment anchorage. At 105 ksi minimum yield and 125–150 ksi tensile it is a quenched-and-tempered alloy product, so confirm coating and any testing requirements at quotation. The grade follows the structural design; order what the engineer of record specified.
What is the MOQ and lead time for this grade?
The minimum order quantity is 500–1,000 pieces. Standard production runs 15–30 days. Bent or custom hook geometries are quoted against the drawing.
What should an RFQ for this grade state?
State the grade, diameter and thread callout (for example 1"-8 UNC), overall length and thread length, hook or straight-rod geometry, coating, and quantity per size — plus destination country and any required documents such as a mill test certificate. Thread and hook lengths differ by supplier and diameter, so read them from your drawing rather than a generic chart.
