Anchor Foundation Bolt In Delhi

Anchor Foundation Bolts

Anchor bolts are heavy-duty fasteners embedded into a concrete or masonry foundation, with part of the bolt protruding so structural elements (such as base plates, columns, machinery) can be anchored securely. For example: they embed the bolt in fresh concrete, or set bolts with templates so that the nut+washer can tighten the structure to the foundation. buidco.in+2aanurajboltsnuts.in+2

They may be called “foundation bolts”, “anchor foundation bolts”, “anchor bolts” for structural anchoring. Some key types: L-type (bend at bottom), J-type (hooked end), straight with plate welded end, etc. aanurajboltsnuts.in+1

These bolts serve to transfer loads (tension, shear, moment) from the anchored structural component into the foundation concrete and then into ground. They therefore need to be sized, embedded, and installed properly.

Typical Specifications & Features (Indian context)

Here are typical specification items you’ll see when sourcing anchor foundation bolts in Delhi/NCR / India:

Material & strength grade:

May use mild steel (MS), carbon steel, or higher tensile steels/alloy grades. For instance, one manufacturer lists material as mild steel, alloy steel, stainless steel in diameter 12-100 mm etc. LG Industries

Grades such as 4.6 / 5.8 / 6.8 / 8.8 / 10.9 / 12.9 are used depending on the load requirement. LG Industries

Standards may include IS (Indian Standard), ASTM, DIN, etc. Rajal Industries+1

Size / dimensions:

Diameter: e.g., from 12 mm up to large diameters (example: 12 mm to 100 mm) in one supplier. LG Industries

Length: depending on embedment and protruding thread. Example: length 300 mm to 6000 mm by one manufacturer. LG Industries

Shape / type:

L‐type (bend at bottom), J‐type (hook end) to provide mechanical anchorage in concrete. hindustancorporation.in.net+1

Straight rod with plate at end or anchor plate welded for higher loads. aanurajboltsnuts.in

Finish / protective coating:

Since these bolts are often in exposed or partially buried conditions, corrosion protection is key. Options: plain (for indoor), zinc-plated, hot‐dip galvanised, primer + paint, etc. Example: “coating: self/ primer/ zinc plating/ hot-dip galvanised”. LG Industries+1

Installation / embedment:

The bolt must be embedded in concrete with adequate length, properly aligned (vertical/horizontal as required), held in position during concrete pour (using templates/spacers) to ensure correct position. buidco.in+1

Application / usage:

Securing steel columns, beams, base plates in building/infrastructure.

Anchoring heavy machinery, industrial equipment, towers, masts.

Infrastructure uses: bridges, fly-overs, wind turbine bases etc. For example one description for anchor bolts notes uses in structural/foundations. Raj
