Frequently Asked Questions
Common questions about our J Type Foundation Bolt manufacturing and supply.
-
What is a J type foundation bolt?
A J type foundation bolt is a cast-in-place anchor bolt with a J-shaped hook at the embedded end. The hook develops strong bond in concrete and resists pull-out and uplift loads, while the threaded top secures base plates, towers and machinery.
-
When should I use a J bolt instead of an L bolt?
J bolts provide higher pull-out resistance than L bolts because the curved hook develops greater bond in concrete. They are preferred for transmission towers, poles, wind/solar structures and any application with high uplift or tensile loads.
-
What sizes of J type bolts are available?
We manufacture J type foundation bolts from M12 to M100 in lengths up to 12 metres on request, with hook radius and embedment made to your drawing.
-
What is the price of J type foundation bolts in India?
Pricing depends on diameter, length, material grade and finish. Stainless steel and high-tensile alloy bolts cost more than mild steel. Share your specification (or drawing, if you have one) for an accurate, no-obligation quote.
-
Which standards do your J type bolts meet?
Our J type foundation bolts conform to ASTM F1554, IS 5624, DIN 529 and ISO 898-1 in bolt grades 4.6, 5.6, 8.8, 10.9 and 12.9.
-
Do you galvanise J type bolts for outdoor use?
Yes. We offer hot-dip galvanising, zinc plating and stainless steel options. Hot-dip galvanised or SS316 is recommended for outdoor, bridge and coastal Chennai applications.
-
Can you supply custom J bolts to drawing PAN India?
Yes. We manufacture custom J type bolts to your exact hook geometry, grade and finish, with Mill Test Certificates and delivery across Mumbai, Bangalore, Hyderabad, Pune, Delhi NCR and all major industrial hubs.
-
What is the typical lead time for bulk J bolt orders?
Lead time varies with order quantity, size and finish requirements. Standard sizes ship faster, while large custom or high-volume orders need additional production time. Contact us with your requirement for a confirmed delivery schedule.
