Questions before ordering anchor bolts & foundation bolts

What grade of anchor bolt do I need?

ASTM F1554 Grade 36 is the most common for general building columns; Grade 55 and 105 are used for higher loads. The structural engineer sets the grade — send the foundation drawing or anchor schedule.

Can you supply anchor bolts with nuts, washers and templates?

Yes. Anchor bolts are usually supplied as sets with heavy hex nuts and washers; templates and plates can be quoted to drawing. Reference MOQ is 500 pcs per specification, subject to quotation.

What is the lead time for anchor bolts?

Standard L and J bolts typically take 25–30 days to produce; stock sizes can ship in 10–15 days. Hot-dip galvanizing is included in the production time.

Buyer brief

Define the bolt shape, embedment length, projection and grade from the foundation drawing before comparing offers.

A category page helps structure the conversation; the selected source and project documents still control the final requirement.

Watch point

Anchor bolt grade, bend dimensions and thread length are set by the structural design; do not change them to match a stock size without engineer approval.

Include in the RFQ

  • Shape (L, J, headed, straight rod), diameter and overall length
  • Thread length at the top, bend length or head/plate detail
  • Grade (F1554 36 / 55 / 105 or other), finish, nuts and washers per bolt
