Foundation Bolts
High-Quality Foundation Bolts Manufacturer & Supplier in India
Durable, Precision-Made Foundation Bolts for Industrial & Commercial Applications
Leading Foundation Bolts Manufacturer in Ludhiana, India
JVS Nut Bolt is a trusted and reliable Foundation Bolt Manufacturer in Ludhiana India, delivering high-strength fastening solutions for infrastructure, construction, and industrial applications. Our foundation bolts are designed with precision engineering, ensuring durability, safety, and long-lasting performance even in extreme environments. Foundation bolts, also known as anchor bolts, are essential components used to secure structures, machines, and equipment to concrete foundations, ensuring structural stability and load-bearing strength.
We manufacture a wide range of foundation bolts in various sizes, materials, grades, and finishes to meet both standard and custom project requirements.
Types of Foundation Bolts We Manufacture
JVS Nut Bolt manufactures all major types of foundation bolts, each designed for specific load conditions and installation methods.
Our comprehensive range ensures you get the right bolt for every application:
J-bolts are the most widely used foundation bolt type. Shaped like the letter J, they are embedded into concrete with the hooked end buried in the foundation and the threaded end projecting upward for fastening. The J-hook provides excellent pullout resistance by mechanically interlocking with the concrete matrix. J-bolts are widely used in column base plates, equipment pedestals, and light to medium structural anchorage.
L-bolts feature a right-angle bend at the embedded end, similar in function to J-bolts but with a sharper 90-degree hook. The L-shaped bend distributes tensile loads over a wider concrete zone, providing higher holding power than straight bolts. They are commonly specified for heavy machinery anchor bases, industrial compressor foundations, and pump skid installations where upward pull forces are significant.
Straight anchor bolts are plain or headed bolts installed into pre-drilled holes using chemical epoxy or mechanical expansion anchors. They are used for post-installed anchorage applications where casting-in bolts is not possible — such as retrofitting, equipment relocation, or structural repairs. Straight foundation bolts are available in fully threaded and partial thread configurations

Frequently Asked Questions
What is the difference between J-bolts and L-bolts?
J-bolts have a semicircular hook (like the letter J) at the embedded end, providing mechanical interlocking with concrete primarily through the curve of the hook. L-bolts have a sharp 90-degree bend (like the letter L) at the embedded end, which offers a slightly different load transfer mechanism with a larger bearing area against the concrete. J-bolts are more common for general structural anchorage, while L-bolts are preferred for heavier machinery bases where higher uplift resistance is needed. Both types are widely used in Indian construction and should be selected based on the structural engineer’s calculation.
What size foundation bolts are used for column base plates?
The size of foundation bolts for column base plates depends on the column load and base plate design as calculated by the structural engineer. For light steel structures and small PEB buildings, M16 to M24 foundation bolts in J-bolt or L-bolt configuration at Grade 4.6 or 8.8 are commonly used. For heavy industrial structures and high-rise buildings, M30 to M56 or larger bolts in Grade 8.8 to 10.9 may be specified. JVS Nut Bolt can supply any size as per your structural drawings and BOQ.
How deep should a foundation bolt be embedded in concrete?
Embedment depth is a structural engineering calculation that depends on the bolt diameter, concrete grade, applied load, and bolt type. As a general rule, J-bolts and L-bolts are typically embedded to a depth of 15 to 40 times the bolt diameter (15d to 40d), but the structural engineer must confirm the exact embedment depth for each project. Adequate embedment prevents pullout failure and cone breakout in the concrete. Our team can provide standard embedment depth reference charts on request.
Can you supply foundation bolts with nuts and washers as a complete kit?
Yes. JVS Nut Bolt supplies foundation bolts as complete fastener kits including the bolt, one or two heavy hex nuts, and a flat washer per bolt — all matching the same material grade and surface finish. Complete kits reduce procurement effort and eliminate the risk of mismatched components on site. Custom kits with double nuts, lock washers, or template plates are also available on request.
